Countywide Vision Zero

The Contra Costa Transportation Authority is part of a collaboration with the county and its cities to develop a Vision Zero framework that supports safer travel for all residents in Contra Costa.

About Vision Zero

Vision Zero is a strategy to eliminate all fatalities and severe injuries that result from traffic collisions. The Vision Zero approach views transportation-related fatalities as preventable, not inevitable, and relies on multi-disciplinary collaboration that is informed by data and is focused on equity. To learn more about our Countywide Vision Zero framework, check out the How-To Guide and Toolbox document.

Close Slip Lane

Removes vehicles' sweeping right turn lane (common countywide collision pattern toward fatal and severe injuries). Shorter pedestrian crossing, more gradual & reduced speed for turning vehicles, better sight lines for visibility, and space for landscaping, stormwater management, and other options. "NO RIGHT TURN ON RED" signs can be proposed.
Locations: Signalized Intersections

Protected Intersection

Corner islands, curb extensions, and color-painted pavement delineating bicycle and pedestrian movements across an intersection. Slower driving speeds, more gradual right turns, and shorter pedestrian crossing distance. Separates bicyclists from pedestrians.
Locations: Signalized Intersections

Bike Box

Designated area ahead of traffic lane that increases visibility of bicyclists ahead of queuing traffic during the red traffic signal phase.
Locations: Signalized Intersections

Advance Stop Markings

A stop bar placed ahead of the crosswalk at "STOP" signs and traffic signals to maximize visibility and reduce potential conflicts with pedestrians from motorists encroaching on the crosswalk.
Locations: Signalized Intersections, Unsignalized Street Crossings

Roundabout

Circular intersections that reduce pedestrian exposure, manage vehicular speeds, and eliminate left turns by requiring vehicular traffic to travel counter-clockwise and exit to the right. Eliminate higher-speed & "T-Bone" collisions; help traffic flow more efficiently, reducing greenhouse gas (GHG) emissions and providing a climate-resilient option that still works in storms/emergencies during an electricity power outage.
Locations: Signalized Intersections, Unsignalized Street Crossings, Roundabouts

Pedestrian Scramble

A type of traffic signal "WALK" phase where all vehicular traffic is required to stop, allowing pedestrians to safely cross through the intersection in any direction, including diagonally. Simultaneous crossings can reduce vehicular time spent at traffic signal.
Locations: Signalized Intersections

Why now?

Fatalities and severe injuries are 2.4x more likely than collisions involving only people in vehicles*
Pedestrians and cyclists account for 38% of injuries and fatalities on Contra Costa County Roads between 2008-2017*

* Transportation Injury Mapping System (TIMS), 2008-2017

Goals

  • Collect and review traffic safety data to identify trends, support local planning, and prioritize countywide efforts
  • Create a “How To” guide for local jurisdictions to implement Vision Zero and safety improvement projects consistently countywide.
  • Integrate Vision Zero as a standard practice in local and regional transportation planning and traffic operations
