Experience with pedestrian safety programs in San Francisco.
San Francisco, California, United States
This report provided key findings from an FHWA funded evaluation of the PedSafe project in San Francisco where ITS countermeasures were implemented to improve pedestrian safety in areas with relatively high injury rates. A portable changeable message speed limit sign (radar speed trailer) was deployed at 51 intersections. In addition, four pole mounted (fixed) changeable message speed limit signs were installed at two mid-block locations. Each system used a radar detector and LED speed display to make drivers aware of excessive speeds and encourage them to slow down.
Agreements were made between the San Francisco Municipal Transportation Agency (SFMTA) and the San Francisco Police Department (SFPD) regarding the planning, implementation, operations, maintenance, and storage responsibilities. Extensive inter-agency coordination was required to determine the proper timing and location of each installation. Training was required to enable agency staff to collect and analyze radar speed data.
SYSTEM COSTS
Cost associated with engineering, administration, and labor were relatively high with respect to material and equipment costs. Specialized training, mobilization, and approval processes were major cost drivers. Complex logistical and scheduling arrangements were required to coordinate with local law enforcement.
