Bellevue Resolution No. 9035 WHEREAS, the worldwide Vision Zero movement is founded on the belief that death and injury on city streets is unacceptable and preventable The City of Bellevue endorses Vision Zero as part of a comprehensive effort to strive to achieve zero traffic deaths and serious injuries on Bellevue streets by 2030. 3
Bellevue Ordinance No. 6334 Prepare and implement a Vision Zero Action Plan that incorporates the 6 Es and includes a clear purpose, outcomes, community involvement, action items and performance measures Update Vision Zero strategies periodically Provide Vision Zero status reports that aggregate and analyze data, document efforts, and communicate progress to the City Council and to the community VISION ZERO BELLEVUE 4
Bellevue ITS Master Plan: Stages in Smart City Development 5
Traditional Crash Reporting Process 5
Crash Based Approach: Lakemont Interchange Case Study From 2005 through 2010 there were 60 collisions recorded by the Bellevue Police Department and the WSP at this location. In 2013, WSDOT built a new roundabout at the intersection of the WB I-90 on- and off-ramps and WLSP SE/180 Ave SE. 6

Conflict-Based Approach: Don t Wait For Crashes to Happen Hyden s Safety Pyramid (adapted from Hyden, 1987) 8
Conflict-Based Approach: Public Involvement Strategy Total Points Placed Ped Facilities 514 32% Bike Facilities 573 35% Ped Behaviors 57 4% Bike Behaviors 22 1% Car Behaviors 452 28% Total 1618 9
Conflict-Based Approach: Video Analytics Strategy Leverage a city s existing traffic camera system to simultaneously: monitor counts and travel speed of all road user groups (vehicle, pedestrian, and bicycle); document the directional volume of all road user groups as they move through an intersection; and, assess unsafe near-miss trajectories and interactions between all road user groups. 10

Partnership Approach Milestone 1: Demonstrate the capability of vision technologies by detecting relevant events in the sample traffic videos (e.g., detecting cars, pedestrians, and bikes and tracking their movements). Milestone 2: Demonstrate an end-to-end system that will, continuously in real-time, detect and store the events, and present aggregated information. Milestone 3: Pilot deployment of end-to-end system in the City of Bellevue traffic control center. The system will run off of a live feed. Milestone 4: Support additional scenarios (e.g., near-collisions of cars with pedestrians and bikes or patterns of bikers crossing a busy intersection). 16
