In general protected bike lanes in Manhattan improve safety for all users:
• Crashes with injuries have been reduced by 17%
• Pedestrian injuries are down by 22%
• Cyclist injuries show a minor improvement even as bicycle volumes have dramatically increased
• Total injuries have dropped by 20%
Protected bicycle lane projects with 3 years of after data include the following: 9th Ave (16th-31st), 8th Ave (Bank-23rd, 23rd-34th), Broadway (59th-47th, 33rd-26th, 23rd-18th), 1st Avenue (Houston to 34th), 2nd Ave (Houston-34th), Columbus Ave (96th-77th) Note: Only sections of projects that included protected bicycle lanes were analyzed Source: NYPD AIS/TAMS Crash Database

The volume-to-capacity ratio is a measure of how “full” a roadway feels and is calculated as a ratio between the measured traffic volume and calculated capacity of the roadway. The result is expressed as a number between 0 and 1. A value of “1” would indicate that the roadway is “full.”

Making it Work Taxi Usage
16 Note: Study period occurred from 4pm to 7pm on weekdays in April 2015.
• From 4pm to 7pm on weekdays there are approximately 16,065 yellow cab trips that start or end in CB 7
• 50% of trips (8,090) are 1.5 miles or less
• 44% of trips (7,000) are wholly within CB 7 (both start and end)
• 32% of afternoon traffic on Amsterdam Ave is taxis (approximately 400 per hour)
• Large potential for a protected lane to shift trips from taxi to Citi Bike

Mixing zones at all non-two way left turns
Improves visibility of cyclists
Provides space to negotiate conflict
Removes left turns from through lanes
Making it Work Left Turns
Creates left turn vehicle storage
![Page 18: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/18.jpg)
Bike lane continues the length of the block
Turning vehicles queue for turn phase
Pedestrians and cyclists have a leading phase to get a head start
Left-turn bays at 79th, 86th, 96th
Making it Work Left Turns
Split phase allows through traffic to move while holding
left turns, up to 23% more green time given to through

Install a paid commercial parking regulation along the east curb of Amsterdam Ave from W. 72nd to W. 96th between 7am and 7pm on weekdays, plus at select locations on west curb
• Maximizes curb space available for
trucks loading or unloading on busy commercial corridor
• Reduces the likelihood of trucks double-parking during peak travel times
• Clear through lanes process traffic more efficiently

Making it Work Parking Consideration
22
25% of the parking space on the corridor will be repurposed
for left turn treatments and pedestrian safety islands
East curb will be converted to daytime
(7am-7pm) commercial loading zones between W 72nd St and W 96th St,
plus targeted loading on the west curb Columbus Avenue at W 106th St
![Page 23: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/23.jpg)
Alternates Studied
23
DOT has studied potential alternatives on nearby
Broadway and Columbus
Note: Any alternative bike route will be paired with pedestrian improvements on Amsterdam to create a safer corridor without bike facilities
Amsterdam Avenue is the preferred northbound route, however it
comes with parking loss and some vehicular capacity reduction
![Page 24: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/24.jpg)
Broadway Route

Existing
Proposed
Buffered bicycle lane against the median in the
northbound direction
Minor traffic impact Design challenges between
95th and 97th
Requires new left turn design
![Page 25: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/25.jpg)
Columbus Ave Route
25
Convert southbound lane to a two way path
No changes to vehicular capacity
Learning curve for users, heavy pedestrian access Requires infrastructure
upgrades
![Page 26: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/26.jpg)
Summary
26
Phase I – Amsterdam Avenue Preferred Route
• Protected bicycle lane provides northbound route for cyclists
• Reduced pedestrian crossing distances with islands
• Design for neighborhood street with safety benefits expected for all users
• Lane reduction with left turn treatments
• High peak hour traffic volumes require some adjustments
• Left turn treatments and paid commercial spaces reduce parkable area
• Traffic flow will be maintained
• Connections to new route via CPW at 77th/78th and 90th/91st
![Page 27: Amsterdam Avenue Northbound Bike Route CB 7 20151110 Final](https://reader033.vdocuments.site/reader033/viewer/2022051117/5695d44b1a28ab9b02a0f9bb/html5/thumbnails/27.jpg)
27
Phase 1 – 72nd – 110th • Incorporate feedback into plan and
present to board for support
• Implement in Spring 2016, nearly two miles of protected lanes and new infrastructure
Phase 2 – South of 72nd • Gather feedback & develop proposals
• Consider network connections
• Coordinate with 2016 capital project at 71st/Amsterdam/Broadway
• Complete improvements at Columbus/65th Street/Broadway
• Any route will require careful planning through complex intersection of 71st/Amsterdam/Broadway
Next Steps
