1 UREU OF LOCL RODS & STREETS 42-3(2) ICYCLE FCILITIES Jan 2006 MINIMUM CROSS SECTIONS FOR CURED STREETS WITHOUT PRKING (Marked icycle Lanes) Figure 42-3G b. Curbed Streets with Parking. The bicycle lane should be located between the parking lane and the through traffic lane with a minimum bicycle lane width of 5 ft (.5 m); see Figure 42-3H. 2. Shared Roadways. On a shared roadway facility, bicyclists and motorists share the same travel lanes without a striped separation. The majority of urban cross sections fall into this category. Shared roadways have particular application where physical constraints (e.g., buildings, narrow sidewalks, environmentally sensitive areas) preclude widening a street to provide bike lanes. Most shared roadways are unmarked, allowing bicyclists to share the outside lane with motor vehicles, as allowed by the Illinois Compiled Statutes. In some instances, it may be advantageous to sign some urban and rural roadways as bicycle routes when providing continuity to other bicycle facilities or when establishing a touring route. On streets where parking is prohibited, the recommended lane width on two-lane, twoway roadways is 4 ft (4.2 m) excluding flags. However, a width of 3 ft (4.0 m) may be considered acceptable. Use these same widths for the outer lanes of multilane highways where bicycle traffic is allowed.

2 UREU OF LOCL RODS & STREETS Jan 2006 ICYCLE FCILITIES 42-3(3) MINIMUM CROSS SECTIONS FOR CURED STREETS WITH PRKING Figure 42-3H Where parallel parking is permitted but a parking lane is not provided, the combination lane should be a minimum of 2 ft (3.6 m) wide. If parking volume is substantial or turnover is high, an additional ft or 2 ft (300 mm or 600 mm) of width is desirable (c) ccommodation on Existing Roads and Streets icycle accommodations can also be adapted to a roadway by marking or remarking the pavement to increase the width of the lane or to add bike lanes. Consider the following: reduce the width of inside traffic lanes; reduce median width, especially with the removal of raised- medians; remove parking possibly in conjunction with providing off-street parking; and/or reduce the number of traffic lanes. This option may be appropriate if, for example, oneway couples are created or if a parallel roadway improvement reduces the traffic demand on an adjacent street that is more suited for bicycle travel.

3 Illinois SPECIL DESIGN ELEMENTS September 200 Notes:. Where articulated buses are expected to use these stops, add an additional 20 ft (6 m) to the bus distances. 2. Provide an additional 50 ft (5 m) of length for each additional bus expected to stop simultaneously at any given bus stop area. This allows for the length of the extra bus (40 ft (2.2 m)) plus 0 ft (2.8 m) between buses. ON-STREET US STOPS Figure HRD COPIES UNCONTROLLED

4 Illinois SPECIL DESIGN ELEMENTS September 200 Notes: Stopping area length consists of 50 ft (5 m) for each standard 40 ft (2.2 m) bus and 70 ft (2 m) for each 60 ft (8.3 m) articulated bus expected to be at the stop simultaneously. us turnout width is desirably 2 ft (3.6 m). For posted speeds under 30 mph, a 0 ft (3.0 m) minimum bay width is acceptable. These dimensions do not include width. Suggested taper lengths are listed below. minimum taper of 5: may be used for an entrance taper from an arterial street for a bus turnout while the merging or re-entry taper should not be sharper than 3:. The minimum design for a bus turnout does not include acceleration or deceleration lengths. Recommended acceleration and deceleration lengths are listed below.

7 Illinois SPECIL DESIGN ELEMENTS March 202 If ramps change direction at landings, the minimum landing size shall be 60 in by 60 in (.5 m by.5 m). 4. Handrails. If a ramp run has a rise greater than 6 in (50 mm) or a horizontal projection greater than 72 in (.8 m), then it shall have handrails on both sides. See the applicable accessible guidelines for additional handrail criteria. 5. Cross Slope and Surfaces. The cross slope of ramp surfaces shall preferably be.5% and no greater than 2%. surfaces shall comply with the criteria for Surface of sidewalks; see Section Edge Protection. s and landings with drop-offs shall have s, walls, railings, or extended surfaces that prevent people from slipping off the ramp. Curbs shall be a minimum of 2 in (50 mm) high. Extended surfaces shall extend a minimum of 2 in from the outside of the handrail. 7. Outdoor Conditions. Outdoor ramps and their approaches shall be designed so that water will not accumulate on walking surfaces. Running Slope Maximum Rise 8.3% but 0% ( :2 but :0) 6 in (50 mm) 0% but 2.5% ( :0 but :8) 3 in (75 mm) Note : These dimensions may only be used when space limitations will not fit a standard ramp. Note 2: Running slopes steeper than 2.5% (:8) are not allowed. LLOWLE EXCEPTIONS TO STNDRD RMP DIMENSIONS (Existing Sites, uildings, and Facilities) Figure 58-.E Curb s ramp shall connect sidewalks at each pedestrian street crossing or crosswalk. For the purpose of this section, a pedestrian crosswalk is defined as that portion of a highway or street ordinarily included within the prolongation or connections of lateral lines of sidewalks at intersections. It also includes any portion of a highway or street distinctly indicated as a crossing for pedestrians by lines or other markings on the surface. It does not include such prolonged or connecting lines from an alley across a street. HRD COPIES UNCONTROLLED 58-.

8 Illinois SPECIL DESIGN ELEMENTS March 202 SIDEWLKS T DRIVEWY PRONS Figure 58-.D s Portions of sidewalks whose running slope exceed 5% and are not following the general grade of an adjacent street or highway are considered ramps (Note: These ramps are different from ramps. See Section for ramps.). The following represents the accessible criteria for ramps:. Running Slope and Rise. s shall have a running slope greater than 5% up to an 8.3% maximum. The maximum rise for any single ramp run shall be 30 in (760 mm). For ramp heights greater than 30 in (760 mm), a series of ramps and landings must be used. s to be constructed on existing building/facility sites or inside existing buildings/facilities may have a running slope which exceeds 8.3% within the rise limitations shown in Figure 58-.E, if space limitations dictate. 2. Width. The minimum clear width of a ramp shall be 36 in (95 mm). Where handrails are provided, the clear width is measured between inside edge of the rails. 3. Landings. s shall have level landings (preferably be.5% and no greater than 2% in all directions) at the bottom and top of each run and shall have the following features: The landing shall be at least as wide as the widest ramp run leading to the landing. The landing length shall be a minimum of 60 in (.5 m) HRD COPIES UNCONTROLLED
