1 AON CENTER ENTERTAINMENT + RESTAURANT DEVELOPMENT Traffic Study Chicago, Illinois Prepared for: The 601 W Companies, Inc.

2 INTRODUCTION Kimley-Horn and Associates, Inc., (Kimley-Horn) was retained by The 601 W Companies, Inc to conduct a traffic study related to development of entertainment and restaurant uses at Aon Center located at 200 East Randolph Street in Chicago, Illinois. The main component of the proposed project includes an observation deck with an exterior glass elevator system combined with multiple retail/entertainment venues and restaurant space totaling 27,375 square feet. The entertainment venues and observation deck are anticipated to have a broad attraction of guests throughout the year with an estimated annual attendance of approximately 2.6 million visitors. Parking will be provided in the Millennium Park Garage, located immediately south of the site with vehicle access provided via intermediate-level Columbus Drive and sub-level Randolph Street. Pedestrian access to/from the garage is located on the south side of upper-level Randolph Street directly across the street from the Aon Center. Access for taxis, transportation network companies (TNC) (e.g., Uber, Lyft), and tour buses will be available curbside at both the upper-level street system. School and charter bus passenger loading is planned along sub-level Randolph Street. Per direction from the Chicago Department of Transportation (CDOT) and the 42 nd Ward Alderman s office, this report includes an analysis of selected intersections in an area generally bound by Lake Street on the north, Randolph Street on the south, Columbus Drive on the east, and Stetson Avenue on the west. Key intersections on the upper-level, intermediate-level, and sub-level were included in this analysis. An aerial view of the subject site and the surrounding roadway network is presented in Exhibit 1. This report documents the study methodology, summarizes data collected, presents an evaluation of the study intersections and site access/circulation, and highlights key findings and recommendations regarding transportation elements of the proposed development.

4 EXISTING CONDITIONS Kimley-Horn referenced recent studies for the area to collect relevant information pertaining to existing land uses in the surrounding area, the adjacent street system, current traffic volumes and multimodal conditions, lane configurations and traffic controls at nearby intersections, on-street parking and other curbside regulations, transit service, and other key roadway characteristics. This section of the report details information on these existing conditions. Area Land Uses The subject site is located on the northwest quadrant of Columbus Drive and Randolph Street located near the Lakeshore East neighborhood of Chicago. The surrounding area is characterized by a mix of office, residential and hotel uses. Aon Center is an office building with a range of lower-level retail and restaurant uses. To the immediate south is Millennium Park with Maggie Daley Park located to the southeast. The Blue Cross Blue Shield office building is located east of the site with high-rise residential buildings further east. North of Aon Center is the Fairmont Hotel with Aqua, including the Radisson Blu hotel, on the east side of Columbus Drive. To the west is the Prudential Tower office building. Existing Roadway Network The Aon Center is bounded by Columbus Drive on the east, Stetson Avenue on the west, Lake Service Street on the north, and Randolph Street on the south. Access to the Aon Center on-site parking deck is provided via intermediate-level Lake Street, west of intermediate-level Columbus Drive. Loading access for Aon Center is provided via sub-level Randolph Street. The area roadways serving the proposed site primarily include Columbus Drive, Stetson Avenue, Lake Street, and Randolph Street. All study roadways are under CDOT jurisdiction. Additionally, a 30 MPH speed limit is assumed for all study roadways, per City Ordinance. The following section summarizes key features of each study roadway. Upper-Level Columbus Drive is a two-way, north-south roadway that runs along the east side of the site. Two travel lanes are provided in each direction with a center median through the study area. At its T-intersection with Randolph Street, Columbus Drive provides a single left-turn lane and a single-right turn lane on the southbound approach. A striped crosswalk and pedestrian signal is provided on Columbus Drive at Randolph Street. At its intersection with Lake Service Street (i.e., Aon Center drop-off/pick-up circle), a shared left-turn/through lane, a shared through/right-turn lane, a raised center median, and two receiving lanes are provided on the southbound approach. A striped area for a potential left-turn lane, a shared left-turn/through lane, a shared through/right-turn lane, a raised center median, and two receiving lanes are provided on the northbound approach. Striped crosswalks are provided on the north and south legs of the Columbus Drive/Lake Service Street intersection. Near its intersection with Randolph Street, CTA bus stops are provided on both sides of Columbus Drive including a CTA layover parking area on the east side of the street. South of the Columbus Drive/Lake Service Street intersection, a loading zone is provided on the west side of the street from 8AM to 12AM. On the east side of the street, metered parking and a food truck stand is designated. Aon Center Restaurant + Observation Deck Page 3

5 North of Lake Service Street, parking is prohibited on the west side of the street; limited metered parking is provided on the east side of the street along with a taxi stand and valet loading zone for the Radisson Blu hotel. As part of an effort to improve pedestrian crossings and calm traffic, CDOT is currently considering options for reconfiguring the lanes, pavement markings, and curbside regulations along upper-level Columbus Drive north of Randolph Street. These improvements will be coordinated with the development plan, but Columbus Drive would continue to provide two travel lanes in each direction with a left- and right-turn lane at its intersection with Randolph Street; therefore, no geometric changes were included in the intersection analysis for future year conditions. Upper-Level Stetson Avenue is a two-way, north-south roadway that provides access from upperlevel Wacker Drive to upper-level Randolph Street along the west side of the site. A single travel lane is provided in each direction. At its all-way stop-controlled T-intersection with Lake Street, Stetson Avenue provides a shared left-turn/through lane on the northbound approach and a shared through/right-turn lane on the southbound approach. At its minor-leg stop-controlled intersection with Randolph Street, a single right-turn lane is provided on the southbound approach. Metered parking is provided along both sides of Stetson Avenue through the study area. In addition to the metered parking, accessible parking spaces and areas for loading activity are maintained. On the west side of Stetson Avenue, two accessible parking spaces are provided south of Lake Street, and one accessible parking space is provided south of Water Street. A taxi stand is provided on the east side of the street along most the site frontage. North of Lake Street, a loading zone is provided on the west side of the street from 9AM to 4PM and 6PM to 7AM, Monday through Friday. South of Water Street, a 15-minute loading zone is provided on the east side of the street. Upper-Level Lake Street is an east-west roadway generally providing a single travel lane in each direction. At its T-intersection with Stetson Avenue, a left-turn lane, an exclusive right-turn lane, and a single receiving lane is provided on the west leg of Lake Street. Between Stetson Avenue and Michigan Avenue, parking is generally prohibited along the south side of the street except for a limited area which is reserved for consulate parking only. In the study area, metered parking is provided along the north side of the street except for areas near the intersections of Lake Street/Beaubien Court and Lake Street/Michigan Avenue, which are reserved for consulate parking only. Taxi stands are provided on the north and south sides of the street, east of Beaubien Court. While Lake Street terminates at Stetson Avenue, a circle drive known as Lake Service Street is provided along the north side of the Aon Center. This circle drive is grade separated from Lake Street; therefore, no vehicular connectivity is provided. Pedestrian access from Lake Street and Stetson Avenue is provided to the Aon Center via a vestibule with stairs down to the building entrance. Access to Lake Service Street is also provided via an outdoor stairway. Upper-Level Randolph Street is an east-west roadway that terminates at Harbor Drive and generally provides two lanes in each direction through the study area. A marked bike lane is provided in each direction between Columbus Drive and Field Drive. Metered parking is available along the south side of the roadway between Columbus Drive and Field Drive, while parking is generally prohibited along the north side of the roadway and east of Field Drive. CTA bus stops, loading zones, and a taxi stand Aon Center Restaurant + Observation Deck Page 4

6 area also provided. At its signalized T-intersection with upper-level Columbus Drive, one through lane and one shared through/right-turn lane are provided on the westbound approach; an exclusive leftturn lane, two through lanes, and two receiving lanes are provided on the eastbound approach. West of Columbus Drive, a dedicated eastbound-to-westbound U-turn lane is provided. A ramp to/from intermediate-level Randolph Street is located west of Stetson Avenue. Striped bike lanes are currently provided along the north and south curb lanes in the study area. CDOT plans to install a dedicated one-way westbound bike lane along the north curb lane of Randolph Street. The new bike lane would extend the existing bike lane striping across the Columbus Drive and Stetson Avenue intersections. With the proposed installation, signal timing adjustments would be provided by CDOT to integrate the addition of a westbound bicycle signal at the Columbus Drive/Randolph Street intersection. The analysis of future year conditions does not include the signal timing adjustments associated with the planned bike lane improvements. A copy of the CDOT bike lane plan is provided in the appendix. Intermediate-Level Columbus Drive is a north-south major arterial roadway generally providing three lanes in each direction through the study area while maintaining a bridge connection over the Chicago River. At its signalized intersection with intermediate-level Lake Street, intermediate-level Columbus Drive provides two through lanes and a shared through/right-turn lane on the southbound approach; an exclusive left-turn lane and three through lanes are provided on the northbound approach. South of this intersection, a ramp down to sub-level Columbus Drive is provided for southbound traffic with a ramp up from the sub-level provided on the northbound approach. At its signalized intersection with intermediate-level Randolph Street, Columbus Drive provides a dedicated left-turn lane, two through lanes, and one shared through/right-turn lane on the southbound approach. The northbound approach provides a dedicated left-turn lane, two through lanes, and two exclusive right-turn lanes. Stairs are provided on the northeast corner of the intersection, providing vertical pedestrian connectivity between the upper and sub-levels of Columbus Drive and Randolph Street. South of intermediate-level Randolph Street, Columbus Drive provides access to the Millennium Park Garage and the Lakeside Garage. Parking is prohibited along both sides of intermediate-level Columbus Drive. Intermediate-Level Lake Street provides access to the Aon Center on-site parking garage, located on the south side of the street. This east-west roadway provides a single travel lane in each direction. A shared left-/right-turn lane and a single receiving lane are provided at its signalized T-intersection with intermediate-level Columbus Drive.

Access to the parking garage for Prudential Tower is provided at the western terminus of intermediate-level Lake Street. Intermediate-Level Randolph Street provides east-west access through the study area. Access to/from Lake Shore Drive is provided via intermediate-level Randolph Street. This roadway generally provides two travel lanes through the study area. At its signalized intersection with intermediate-level Columbus Drive, intermediate-level Randolph Street provides an exclusive left-turn lane, one through lane, and one shared through/right-turn lane on eastbound approach; an exclusive left-turn lane, two through lanes, and a right-turn lane are provided on the westbound approach. The west leg of the Aon Center Restaurant + Observation Deck Page 5

7 intersection is a ramp to/from upper-level Randolph Street. Parking is prohibited on intermediate-level Randolph Street. Stairs are provided on the northeast corner of the intermediate-level Randolph Street/Columbus Drive intersection, providing pedestrian connectivity between the upper and sublevels of Columbus Drive and Randolph Street. Sub-Level Columbus Drive is a north-south roadway with a single travel lane provided in each direction. Sub-level Columbus Drive provides access to the parking garages and loading docks for multiple hotels, residential towers, and office buildings located in the site vicinity. Access to the Millennium Park Garage is also provided via sub-level Columbus Drive; the parking garage entrance/exit is located on the south leg of the Columbus Drive/Randolph Street intersection. At its intersection with sub-level Randolph Street, ramps to/from intermediate-level Columbus Drive are provided on the north leg of the intersection. Stairs also provide pedestrian connectivity between the three levels. Metered parking is provided along sub-level Columbus Drive through the majority of the study area. Sub-Level Randolph Street is an east-west roadway with a single travel lane provided in each direction. Sub-level Randolph Street provides access to area parking garages and loading docks; access to the Lakeshore East development is provided at its eastern terminus at sub-level Harbor Drive. West of sub-level Columbus Drive, sub-level Randolph Street maintains access to a shared loading dock for the Aon Center on the north side the street and access to the Lakefront Busway on the south side of the street. With the proposed development, charter bus passenger loading/unloading activity would be accommodated along the north curb of sub-level Randolph Street, just west of sublevel Columbus Drive. West of Columbus Drive, public parking is generally prohibited while east of Columbus Drive, metered parking is provided on the south side of the street. Non-Motorized Transportation System Facilities and services accommodating numerous transportation mode choices are available within the vicinity of the Aon Center. Rail The following rail transportation options are located within an approximately ten- to fifteen-minute walk to/from the site: CTA State/Lake Station: Access to the CTA Brown, Green, Orange, Pink, and Purple Lines via the elevated station and Red Line via the subway station Wabash/Randolph Station: Access to the CTA Brown, Green, Orange, Pink, and Purple Lines Dearborn/Washington Station: Access to the CTA Blue Line Aon Center Restaurant + Observation Deck Page 6

8 Metra Millennium Station: Access to the Metra Electric District and the Northern Indiana Commuter Transportation District South Shore Line Bus Additionally, the surrounding area is served by multiple CTA bus routes with stops located within a five- to ten-minute walk to/from the site: Route 6: Jackson Park Express Provides service between 79 th /South Shore to Wacker/Columbus Nearest stop located at upper-level Wacker Drive/Columbus Drive Route 124: Navy Pier Provides service between Union/Ogilvie State and Navy Pier Nearest stop located at upper-level Wacker Drive/Columbus Drive Route 20: Columbus Provides service between Madison/Austin and Randolph/Columbus Drive Nearest stop located at upper-level Columbus Drive/Randolph Street Route 4: Cottage Grove Provides service between 95 th /St. Lawrence and Columbus/South Water Nearest stop located at upper-level Columbus Drive/Randolph Street Route 60: Blue Island/26th Provides service between Cicero/24 th Place and Harbor/Randolph Nearest stop located at upper-level Columbus Drive/Randolph Street DIVVY Four DIVVY bike share stations are located within reasonable walking distance of the subject site such that people will likely consider making a shared bike trip. These station locations are outlined below: Upper-level Randolph Street/Columbus Drive (in front of the Blue Cross Blue Shield building) Stetson Avenue/South Water Street (northwest corner of the intersection) Michigan Avenue/Lake Street (northeast corner of the intersection) Michigan Avenue/Washington Street (west side of Michigan Avenue, between Randolph Street and Washington Street) Since taxi and walking trips make up approximately 27 percent of the mode spilt for the restaurant trips and approximately 14 percent of the mode split for the entertainment and observation deck trips in this area, the bike share system offers increased travel options and convenience. The nearby stations are an enticing draw for visitors looking to explore the City. The bike share system is Aon Center Restaurant + Observation Deck Page 7

9 reasonably expected to facilitate some degree of mode shift from walking and taxi to biking for those traveling to other destinations in the Loop, along the lakefront, or north of the Chicago River. Traffic/Pedestrian/Bicycle Counts The proposed observation deck and retail/entertainment venues are anticipated to have a broad attraction of guests throughout the year, but are expected to draw higher attendance between late Spring to early Fall. As such, traffic counts were collected primarily in August 2016 prior to the Labor Day holiday for weekday, Friday, and Saturday conditions with supplemental Sunday counts collected in September Table 1 summarizes the locations, dates, and time periods for the traffic counts. Exhibit 2 illustrates the count locations relative to the site. Table 1.

The count locations and periods were coordinated with CDOT staff to coincide with typical peak hours on the adjacent streets, periods of anticipated peak visitor activity for the various restaurant, entertainment, and retail components of the development program, and days with various levels of typical commuter and tourist activity. The observatory and retail/entertainment venues are not planned to open until after the typical morning peak period ends at 9:00 AM. Thus, most counts do not include morning peak period data. However, such data was collected at the intermediate and upper-level Randolph Street/Columbus Drive intersections as they are the highest volume intersections in the study area and the counts provide context for the relative traffic volumes experienced throughout much of the day. The Sunday counts are intended to provide context in comparison with Saturday data for weekend conditions and thus were not collected at all Aon Center Restaurant + Observation Deck Page 8

10 intersections. Based on review of these counts, the Sunday count data indicates similar traffic volumes as the Saturday counts at key intersections. Based on the anticipated daily and hourly distribution of traffic associated with the proposed observation deck and retail/entertainment uses, and the peak hours of the existing roadway network, the following peak hours were selected for the analysis. Thursday PM Peak Hour: 4:45 PM to 5:45 PM Friday Midday Peak Hour: 12:00 PM to 1:00 PM Friday PM Peak Hour: 4:45 PM to 5:45 PM Saturday Midday Peak Hour: 12:00 PM to 1:00 PM Saturday PM Peak Hour: 4:45 PM to 5:45 PM The existing peak hour traffic volumes for these periods are presented in Exhibits 3A to 3C. Nonvehicular volumes (pedestrians and bikes) for the same peak hours are shown on Exhibits 4A to 4C. Aon Center Restaurant + Observation Deck Page 9

18 FUTURE CONDITIONS This section of the report outlines the key characteristics for the proposed development, estimates the trip generation, and projects traffic patterns on the surrounding street system during peak hours. Proposed Development Plan Land Uses The proposed project consists of approximately 27,375 square feet of restaurant space and an entertainment component with multiple venues including an observation deck with an exterior glass elevator system. The observation deck and retail/entertainment venues are anticipated to attract an estimated annual attendance of approximately 2.6 million visitors. Private Auto Access on its proximity and pedestrian connectivity, parking is planned in the Millennium Park Garage. Vehicular access to off-site parking in the Millennium Park Garage is available along intermediatelevel Columbus Drive. Thus, most vehicular traffic associated with visitors arriving by personal auto is not expected to be adjacent to the site on the upper-level street system. Taxi / CTA Bus / Tour Bus The upper-level roadways and intersections will serve visitors who are arriving via taxi, TNCs (e.g., Uber, Lyft), and tour buses (similar to double decker buses that allow riders to hop on/off over the course of the day with a single ticket). Passenger loading for Aon Center currently occurs along the north side of Randolph Street adjacent to the site. Some level of taxi and TNC activity for the observatory and retail/entertainment venues is expected to occur here. The west curb of Columbus Drive presents an opportunity for such loading activity as well. A recommended plan for loading along the west curb of upper-level Columbus Drive is presented and discussed later in this report. In order to accommodate these loading functions, the existing CTA bus stop along the west side of Columbus Drive may need to be adjusted; therefore, coordination with the CTA is needed. School/Charter Bus In addition to tour buses, groups are expected to travel to the site by school or charter bus. Charter bus passenger loading and unloading activity is planned for the north curb of sub-level Randolph Street just west of Columbus Drive. Buses would directly access the sub-level loading area via the ramp from southbound intermediate-level Columbus Drive. A ramp in the reverse direction from the sub-level to northbound intermediate-level Columbus Drive would provide an exit route. The sub-level loading area is also convenient for buses associated with McCormick Place conventions and hotels that have access to the Lakefront Busway as its northern terminus is located on sub-level Randolph Street immediately east of the proposed charter bus loading area. This loading area will be accessible via new elevators in the southeast corner of the site that would provide vertical circulation between the sub-level and Aon Center s concourse level (one building level below the upper-level street system).

19 Pedestrians Pedestrians walking to/from the site from other downtown origins will utilize the existing sidewalk system and other connections through the Aon Center such as the Chicago Pedway. Although arriving to the general area via auto, visitors that park in the Millennium Park Garage will also be pedestrians adjacent to the site as they cross upper-level Randolph Street between the Aon Center and the parking garage elevator access. Pedestrians are able to cross at the west crosswalk of the Randolph Street/Columbus Drive intersection. Pedestrian access to the new uses are proposed via south side of the site and the upper-level sidewalk with the restaurant spaces in the southwest portion fo the site and the observatory and retail/entertainment uses in the southeast portion of the site. Loading/Delivery Accommodations for delivery/service truck activity at the site are planned with a shared loading dock on sub-level Randolph Street west of sub-level Columbus Drive. Trip Generation The following sections of the report describe the data and methodology used to estimate peak-hour traffic anticipated with development of the proposed restaurant use and entertainment venues. Mode Share Due to the highly walkable urban context, availability of multiple convenient public transportation and multimodal options, and access to a variety of nearby uses, developments in the surrounding area generally exhibit considerable non-auto travel characteristics. For the proposed restaurant use, trip generation projections reference data from the River East Area Traffic and Parking Operation Review, prepared by Barton-Aschman Associates, Inc., for the City of Chicago in Based upon the data for restaurant uses in the River East study, taxis were identified to represent 27 percent of restaurant auto-trips. All other vehicle trips were assumed to be personal auto trips. Based on the nature of the proposed restaurant use and the location of the development site, the personal auto trips estimated for the restaurant were assumed to self-park at the Millennium Park Garage or another nearby garage. Restaurant trips arriving via taxi were assumed to utilize the existing curbside area on Randolph Street along the south side of the site. The observatory and entertainment venue component of the development plan is expected to draw patrons via multiple modes of transportation including auto, transit, coach/tour bus, walking, bicycle, and taxi. While there are differences between the proposed observation deck and others in the downtown area, the transportation characteristics exhibited by visitors of the proposed observation deck and companion entertainment venues is expected to be like those at other observation decks nearby. Thus, mode share observations were performed on Jackson Boulevard outside the entrance to the Willis Tower Skydeck on Friday, October 14, 2016 from 11:00 AM to 1:00 PM. The observations consisted of counting the number of visitors entering the Skydeck at street level and documenting their mode of arrival, including taxi/tnc, bus, and walking. Visitors arriving on foot could include people driving and parking in a nearby garage or Metra/CTA Rail riders that complete their trip by walking to the Skydeck. Thus, data published in the River East study, was referenced to Aon Center Restaurant + Observation Deck Page 18

This considers available parking at the Millennium Park Garage. As a reference, the Theater use referenced in the River East Study has 40% auto and 44% walk/transit. Trip Generation Rates Due to the highly walkable urban context, availability of convenient public transportation and multimodal options, and access to a variety of nearby uses, developments in the surrounding area generally exhibit considerable non-auto travel characteristics. For the proposed restaurant use, trip generation projections reference data from the River East Area Traffic and Parking Operation Review, prepared by Barton-Aschman Associates, Inc., for the City of Chicago in This document includes local trip generation data and includes consideration for the use of non-auto modes of travel Aon Center Restaurant + Observation Deck Page 19

The entertainment venues are expected to have broad seasonal appeal for visitors, but will have variation throughout the year, days of the week, and times of day. In order to understand these characteristics, Kimley-Horn coordinated with the proposed operator of the entertainment venues to identify monthly, daily, and hourly distribution of visitors based on their experience with other similar venues. The projected annual attendance for the observatory and entertainment venues is 2.6 million visits. This includes 2 million visits to the observatory as the main venue and 1 million visits to the other venues combined with a shared visit factor of 40 percent attending the observatory in addition to another of the entertainment venues. A summary of these monthly, daily, and hourly distribution factors and the estimated site-generated traffic attributed to the entertainment venues and observation deck is provided in Tables 5A to 5C.

25 As shown in Tables 5A to 5C, for purposes of a conservative analysis, the anticipated trip generation was based on the estimated attendance for the month of July, which is expected to have the highest monthly attendance throughout the year. Using these distribution factors summarized in Table 5 and an assumption for average visitor length of stay (2 hours) and average vehicle occupancy (2.2 persons/vehicle based on data from the Stratosphere Observation Deck in Las Vegas), the anticipated trip generation was calculated for each peak hour. These estimated trips were then added to the restaurant trip generation in order to generate the overall site-generated traffic projections presented in Table 6.

The mode split for the entertainment venues + observation deck is based on empirical data from the Willis Tower Skydeck summarized in Table Inbound and outbound taxi trips were assumed to originate outside of the study area and then travel to the curbside drop-off/pick-up area to pick-up or drop-off their passenger prior to traveling out of the study area. Aon Center Restaurant + Observation Deck Page 25

27 Directional Distribution The estimated distribution of site-generated traffic on the surrounding street system as it approaches and departs a site is a function of several variables such as site access, directional flow and connectivity of area streets, the ease with which motorists can travel over various sections of the road network, and prevailing traffic volumes/patterns. The estimated trip distribution for the proposed development is heavily based on existing general traffic patterns within the study area and the roadway connectivity associated with the upper- and intermediate-levels of Columbus Drive and Randolph Street. As such, the directional distribution shown in Table 7 summarizes the anticipated direction for which vehicles will travel to and from the site. Table 7. Estimated Trip Distribution Roadway Orientation Auto Trips Taxi Trips Inbound Outbound Inbound Outbound North via Upper-Level Columbus Drive 50% 50% North via Intermediate-Level Columbus Drive 25% 25% South via Intermediate-Level Columbus Drive 1 40% 40% East via Upper-Level Randolph Street East via Intermediate-Level Randolph Street 25% 25% West via Upper-Level Randolph Street % 50% West via Intermediate-Level Randolph Street 2 10% 10% Total 100% 100% 100% 100% 1 Trips traveling to/from the south were assumed to access the Millennium Park Garage via the driveways on Columbus Drive south of Randolph Street; therefore, these trips are not expected to travel through the study intersections. 2 Trips traveling from the west access intermediate-level Randolph Street via the ramp on upper-level Randolph Street west of Stetson Avenue; trips traveling to the west from intermediate-level Randolph Street utilize the same ramp to access upper-level Randolph Street. Site Traffic Assignment The site traffic assignment, representing traffic volumes associated with occupancy of the proposed development, is a function of the estimated trip generation and the directional distribution. The site traffic assignment is presented in Exhibit 5 for personal autos and Exhibit 6 for taxis. The total weekday peak hour site traffic assignment (personal autos + taxis) is presented in Exhibit 7. It should be noted that in addition to the personal autos and taxis, the anticipated charter buses traveling to and from the Aon Center were assigned to the roadway network. As shown in Exhibits 5 and 7, these trips are expected to use the sub-level intersection of Columbus Drive/Randolph Street to access the passenger loading and unloading area along the north curb of sub-level Randolph Street just west of Columbus Drive.
