2 Topics How does the City assess roadway conditions? What is the City s standard? What has occurred at Snoqualmie Parkway and Fisher Ave.? What are we currently doing? 2

3 How does the City assess roadway conditions? 3

4 Level of Service (LOS) Level of service: A quantitative measure of transportation system operating conditions that helps interpret the significance of roadway/intersection traffic delays generally measures speed, travel time, traffic interruptions and convenience. LOS evaluates average vehicle control delay 4

5 LOS for Intersections Non-signalized intersections determined by the length of delay for each separate turning or through movement Signalized intersections measures control delay, indicating driver discomfort, fuel consumption and increased travel time. 5

6 LOS Definition for Delays at Intersections LOS Signalized Non-signalized A 10 sec 10 sec B sec sec C sec sec D sec sec E sec sec F 80 sec 50 sec 6

7 City s Intersection Standards All intersections at LOS D or better For signalized intersections - delays of 35 to 55 seconds For non-signalized intersections - delays of 25 to 35 seconds 7

13 City Road Work Standard City uses the Manual on Uniform Traffic Control Devices (MUTCD) as its standard for traffic control related work 13

14 Manual on Uniform Traffic Control Devices Issued by the Federal Highway Administration Nationwide standard for traffic signs, road surface marking, and signals that are designed, installed and used. All traffic control devices must legally conform to these standards. 14

15 MUTCD Signal Warrants Requirements Engineering study to evaluate whether a traffic signal is justified based on whether at least one of 9 (conditions)warrants is satisfied. Needed data includes: a 24-hour vehicle volume count of inbound traffic on each intersection leg, statistical speed data on the main street approaches, pedestrian crossing volumes crash history 15

16 What are the MUTCD requirements for a Full Signal? To justify a traffic signal per MUTCD the City will need to meet one of the following 9 signal traffic warrants as follows: 1 Warrant Eight-Hour Vehicular Volume Criteria Large number of intersecting traffic: 600 veh/hr on Parkway and 150 veh/hr on Fisher Ave Interrupting traffic with 900 veh/hr on Parkway and 75 veh/hr on Fisher Ave in an 8 hour period Minimum 115 veh/hr at Fisher Ave 2 Four-Hour Vehicular Volume 3 Peak Hour 100 veh/hr on Fisher Ave 4 Pedestrian Volume 107 ped/hr, 133 ped /hr in the peak hour 5 School Crossing No schools in the immediate vicinity where school children cross Snoqualmie Parkway 6 Coordinated Signal System If a traffic signal is needed to maintain proper movement of vehicle. 7 Crash Experience 5 or more crashes per year 8 Roadway Network If needed to encourage concentration and organizing of traffic flow on a roadway network 9 Intersection Near a Grade Crossing If the proximity to the intersection of a grade crossing on an intersection approach controlled by a Stop or Yield sign The satisfaction of a traffic signal warrant or warrants shall not in itself require the installation of a traffic control signal. 16

17 MUTCD Criteria for a Full Signal The applicable specific minimum threshold criteria for Snoqualmie Parkway and Fisher Ave. intersection: Based on the 2007 traffic signal warrant analysis, the intersection does not meet the specific minimum threshold for a signal. hourly vehicle volumes to be met for a specified minimum number of hours throughout an average day, minimum pedestrian volume crossing the street for a minimum number of hours a day, minimum number of crashes that have occurred within a one-year period that are correctable by installation of a signal, some combination of these. 17

19 What is a HAWK Signal A traffic control device that provides protected pedestrian crossings, stopping road traffic only as needed. Where standard traffic signal 'warrants' prevent the installation of standard threecolor traffic signals, the HAWK Signal is an alternative. 19

21 MUTCD Pedestrian Hybrid Beacon (HAWK signal) Warrant Requirements HAWK signal is referred to as Pedestrian Hybrid Beacons by the MUTCD. A pedestrian hybrid beacon is used to facilitate pedestrian crossings at a location that does not meet traffic signal warrants. Perform engineering study that evaluates whether a pedestrian hybrid beacon is justified based on whether a single warrant is satisfied. Data needed to evaluate this warrant includes: 24-hour vehicle volume count of inbound traffic on each intersection leg, statistical speed data on the main street approaches, pedestrian crossing volumes length of crosswalk The warrant requires minimum threshold pedestrian crossing volumes to be met for at least one hour a day with minimum threshold vehicle volumes occurring on the main street during the same hour. Based on these criteria, it was determined that the Pedestrian Hybrid Beacon is warranted by the City s engineer. 21

22 2015 Warrant Analysis Data collected on November 12, Warrant Eight-Hour Vehicular Volume CONCLUSION Actual Conditions Volume on the higher-volume minor approach (Fisher Ave) < 56 veh/hr. Minimum threshold is 84 vehicles per hour. Does not meet Warrant 1. Threshold for Condition B is 504 veh/hr on Parkway and 42 veh/hr Fisher. Does not meet Warrant 1. Volume does not meet Warrant 2 thresholds for any hour of the day. Does not meet Warrant 2. The existing pedestrian traffic shows that there is some demand for crossing Four-Hour Vehicular Snoqualmie 2 Volume Parkway at the study intersection. There are bus stops, residences, and 3 parks Peak on both Hour sides Does of not the meet road, Warrant as 3. well as a golf course on the north side. Pedestrian Volume One 4 option for a safer crossing Three pedestrians is a Pedestrian crossing the major Hybrid roadway Beacon during the peak (PHB). hour. Does not meet Warrant 3. 5 School Crossing No schools in the immediate vicinity. Not applicable. 6 Coordinated Signal System Not applicable. 7 Crash Experience Does not meet Warrant 7. 8 Roadway Network Not applicable. 9 Inter. near a Grade CrossingNot applicable. Conclusion: The Snoqualmie Parkway and Fisher Avenue SE intersection does not meet traffic signal Warrants 1, 2, 3, 4, or 7. The existing vehicle and pedestrian volume at the intersection does not justify a traffic signal. 22

23 Project History Perteet completed full traffic signal design in October, 2007* Project was advertised for bid in April, 2008 Low bid was 55% higher than Engineer s Estimate and Council rejected all bids King County converted the signal design to County standards in September, 2010** Project was not bid due to lack of funding and did not meet MUTCD standards *Designed per WSDOT standards because the City contracted with WSDOT for maintenance. **Design was changed to County standards because the City switched to King County for maintenance. 23

24 What is the City currently doing? City is currently designing the Pedestrian Activated (HAWK) signal for the Parkway/Fisher intersection The goal of this is to have shelf ready design for the next grant cycle. 24

26 Next Steps Design is 90% complete and is waiting for city direction to proceed. City will apply for grants in 2016 to fully fund the HAWK signal installation. Bidding the signal Construction 26
