SHORT TERM ACTION LONG TERM CHANGE

“Fatalities have increased eight consecutive quarters beginning with the fourth quarter of 2014.” NHTSA, Early Estimate of Motor Vehicle Traffic Fatalities For the First 9 Months of 2016

- www.aceable.com/safe-driving-videos/car-accident-statistics

On city streets, most drivers ignore posted speed limits, and instead drive the speed at which they feel safe. That speed is set by the cues provided by the environment. Are there other cars near me? Is an intersection approaching? Can I see around that corner? Are there trees and buildings near the road? Are there people walking or biking nearby? And: How wide is my lane? - Why 12-Foot Traffic Lanes Are Disastrous for Safety and Must Be Replaced Now, Jeff Speck

DESIGN SPEED

Low-cost, temporary changes to the built environment intended to improve neighborhoods.

TACTICAL URBANISM

• Test solutions before investing.

• Decrease cost of street safety improvements.

• Improve response time.

• Empower local people.

Seems simple. Right?

People make changes in our streets all the time.

Curb Extension

Back-In Diagonal Parking

Bike Corral

Signage

Cones

Installation Zone

Shared Space Bikes & Peds

Vehicular Travel Way

Physical Barrier

Notes: Before installation begins, cones will be placed from Ash to Chestnut to establish a work zone and reduce the street from two to one lane of traffic. All workers will wear traffic vests and remain within the designated work area. The cones will remain in place for the duration of the project (6/22 & 6/23).

Back in parallel parking will be striped using traffic tape in front of the Centerville Garage to clearly communicate that Canal Street will continue with one lane of traffic. A physical barrier will be located at the start of the shared space block to further communicate that the single travel lane condition will continue. Paint will be used to demarkate the continuation of the single travel lane through the shared space area extending from Pine to Chestnut. After the intersection with Chestnut, Canal Street will expand to two lanes.

Signage will be provided approaching the intersection of Ash and Canal to alert drivers to a change in traffic pattern and to reduce their speed. The diagonal parking, the Physical Barrier, the Bike Corral, and other unusal activity will effectively lead to a reduction in travel speed well in advance of the shared space, and continuing into this portion of the street.

Important street design lessons to keep in mind.

“FOR RURAL AND URBAN ARTERIALS, LANE WIDTHS MAY VARY FROM 10 TO12 FEET.”

- AASHTO, the American Association of State Highway and Transportation Officials, the standards setting body which publishes specifications, test protocols and guidelines, which are used in highway design and construction throughout the United States.

“INCREASED LANE WIDTHS ARE RESPONSIBLE FOR APPROXIMATELY 900 ADDITIONAL TRAFFIC FATALITIES PER YEAR.”

- Robert Noland, “Traffic Fatalities and Injuries: The Effect of Changing Infrastructure and Other Trends”, Center for Transportation Studies, 2002.

IN 1972, 472 TRAFFIC SIGNALS WERE REMOVED IN PHILADELPHIA.DATA COLLECTED ON 199 STREETS.CRASHES REDUCED 24%.SEVERE INJURY CRASHES REDUCED 63%.

SEVERE PEDESTRIAN INJURY CRASHES REDUCED 68%.

“TRAFFIC ENGINEERS IN PHILADELPHIA BELIEVE THAT THE SAFETY BENEFIT STEMS FROM ELIMINATION OF THE LOCAL HABIT OF SPEEDING TO BEAT THE RED LIGHT.”
