Vision Zero pledges from the Bellevue Community

Bellevue residents are taking the personalized Vision Zero pledge. City staff asked residents what they would like to see to improve the safety of our streets and achieve Vision Zero in Bellevue. Responses from an elementary grade five safety patrol and our Bellevue Essentials 2022 class cohort can be found here.

‘Tune In, Not Out’ Education Campaign

One in four drivers involved in fatalities or serious injuries in Bellevue is under 25 years old. Inattentive and distracted driving is associated with 20 percent of local fatal and serious injury collisions. Tune In, Not Out (TINO) is an educational campaign partnership with the Bellevue School District and Washington DECA against teen distracted driving. The partnership began in 2019, and a case study was shared with the City Council in February 2020.

Rapid Build Data Driven Safety Program

The City Council has allocated $2.5 million in the city’s budget for 2021–27 to implement rapid build road safety projects along five High Injury Network (HIN) corridors, including Northeast 8th Street, east of downtown, and Factoria Boulevard (see CIP PW-R-205). Funding will implement safety countermeasures such as radar feedback signs, pedestrian crossings, medians, and before/after assessments to help inform future investments.

Road Safety Assessments

One element of the Safe Streets strategy is to conduct Road Safety Assessments (RSA). Assessments so far include:

Leading Pedestrian Intervals

A leading pedestrian interval, or LPI, is when people crossing the street are given the WALK sign before the adjacent vehicles are given a green light. A LPI is one tool the city uses to help improve safety (see one page flyer).

Speed Management Plan

Released in January 2024, the Speed Management Plan (SMP) is the city's first plan to address speed management on arterial roadways with a posted speed limit of 30 mph or greater. Similar to the Residential Traffic Guidebook for local streets, the countermeasure toolkit in the SMP details engineering solutions that may be appropriate for a given arterial corridor based on land use, speed limit and impact to emergency response vehicles.

Slow Zone Pilot
In response to community concerns about high vehicle speeds and pedestrian safety, the Transportation Department lowered the speed limit of all streets in the Surrey Downs neighborhood from 25 mph to 20 mph in fall 2020. This project was selected from more than 100 candidate locations in the city following a prioritization process by the city’s Neighborhood Traffic Safety Services group. The city will evaluate the effectiveness of the speed limit change through before and after traffic studies that measure vehicle speeds and through community feedback.

Micromobility Regulations

At the City Council’s direction, staff is working with the Transportation Commission to review and recommend revisions to city code regulating the use of motorized foot scooters (commonly called e-scooters). Currently prohibited from using sidewalks and most arterial streets, potential regulatory changes could expand access to opportunity for people using this increasingly popular mobility option while emphasizing safety as a priority.

The City of Bellevue is committed to participating in and contributing to the national Vision Zero cities network so that we’re collectively moving towards zero together. The following highlight some of these recent activities.

Strengthening Mobility and Revolutionizing Transportation (SMART) Award

On Mar 14, 2024, the City of Bellevue was selected for an award of $1.427 million in Federal funding through the U.S. Department of Transportation’s Strengthening Mobility and Revolutionizing Transportation grant program. See the press release and the award recipient list here: FY 2023 SMART Awards. The award will support the city in operationalizing real-time traffic signal safety interventions using video analytics, edge computing, deep learning, and smart sensors that will improve intersection safety for vulnerable roads users.  Bellevue’s SMART grant includes an exciting partnership with the City of Tacoma to demonstrate scalability and technology portability during subsequent phases of this project.  Together with Tacoma, this project can provide safety enhancements for greater population of Historically Disadvantaged Communities.  Further information on these activities is available in the grant application.

Safe Streets and Road for All Grant Award

On Dec. 13, 2023, the City of Bellevue was selected for an award of $2.787 million in Federal funding through the U.S. Department of Transportation’s Safe Streets and Roads for All grant program in the Planning and Demonstration categories. See the press release and the award recipient list here: FY 2023 SS4A Awards. The award will support the city in carrying out road safety audits, speed studies, developing a separated bike lane design guide, and creating speed safety camera procedures. The City will additionally conduct demonstration activities testing approaches for protected turn phasing for pedestrians, adaptive pedestrian signal controls, aesthetically treated crosswalks, and cellular vehicle-to-everything technologies. Further information on these activities is available in the grant application

Vision Zero and Technology Roundtable

On Jan. 11, 2022, the City of Bellevue collaborated with ITE in organizing a Vision Zero & Technology Roundtable in Washington, DC that brought together public and private sector leaders to share the latest technological developments, identify problems, develop strategies, and pursue the most effective set of actions to improve safety (Roundtable Report).

Industry Acknowledgement

Over the years, Bellevue has continued testing innovative ideas to further traffic safety—receiving acknowledgments along the way.

  • In 2021, the city was recognized by the National Operations Center of Excellence with a runner-up award in the Best TSMO Project category (Transportation Systems Management and Operations) for its video analytics work to identify near-crash data on city streets.
  • In 2019, Bellevue was recognized as both a Silver-level Walk Friendly Community and Silver-level Bicycle Friendly Community
  • In 2016, the U.S. Department of Transportation awarded Bellevue a Safer People, Safer Streets Initiative Award for its data collection activities supporting the Pedestrian and Bicycle Implementation Initiative.

The City of Bellevue cultivates an organizational culture that identifies traffic fatalities and serious injuries as unacceptable and preventable. The following highlight some of these recent activities.

 

Vision Zero Design Thinking Workshop

On Mar. 10, 2022, the City of Bellevue staff benefited from an Arizona State University sponsored Cloud Innovation Center workshop at City Hall that involved design thinking safe systems solutions to improve road safety for people walking and bicycling (Workshop Report).
 

Vision Zero Summit

As part of the work to create a Strategic Plan, the city organized a Bellevue Vision Zero Summit (event program – 56 MB) on Feb. 13, 2019 at Overlake Medical Center. Experts from across the state and nation spoke and Bellevue TV made video recordings of the presentation topics:

Crash Map

To achieve the 2030 goal, it’s important to understand the problem and to develop the right tools to address it. Knowing where, when and what type of collisions occur is critical to eliminating them. In December 2021 city staff updated the collision map to a dynamic dashboard with enhanced functionality, such as the ability to interactively search through data on fatal and serious injury collisions over a 10-year period.

Vision Zero Collision Dashboard

Vision Zero Collision Dashboard

The Washington State Department of Transportation also maintains a crash data portal with state and local statistics over a 10-year period.

The City of Bellevue is committed to promoting collaboration and partnerships with the community and industry to achieve its desired Vision Zero outcomes. The following highlight some of these recent partnerships.

Video Analytics Partnerships

In partnership with private sector, government and non-profit organizations, Bellevue is using its extensive system of 360-degree, high-definition traffic cameras to identify near-crash traffic conflicts between people driving, walking and bicycling. The insights derived from processing these video feeds with artificial intelligence algorithms help the city proactively identify safety improvements for intersections.

Working with Amazon Web ServicesAdvanced Mobility Analytics GroupOusterOutsightSCATS, and Blue-Band the city conducted a Passive Pedestrian Detection Phase Extension Pilot that took the application of artificial intelligence to the next step of real-time outcomes. By intervening in the moment, this safety pilot was evaluated on its ability to proactively prevent a potential vehicle pedestrian collisions. Results from the study reveal that inputs from the passive pedestrian detection system act as an input to the city’s adaptive signal control system - similar to how a vehicle detection loop can extend the green time for a person driving - and could help the system be responsive to all modes (see City of Bellevue report).

Working with Amazon Web Services, Advanced Mobility Analytics Group, Ouster, Outsight, Blue-Band, SCATS, and Fehr & Peers the city conducted a before-and-after evaluation on the safety impacts of high visibility crosswalks using video analytics. Results from the study revealed that high visibility crosswalks reduce vehicle-pedestrian conflicts by 56 percent (see Fehr & Peers report).

Working with Microsoft, Advanced Mobility Analytics Group, and Jacobs, the city conducted a before-and-after evaluation on the safety impacts of leading pedestrian intervals. The pilot study included 20 intersections in the Downtown and Crossroads areas with traffic cameras that were used to observe more than 650,000 road users. Results from a study of 10 pedestrian crossings on three (3) signalized intersections in Bellevue showed a 42% percent reduction in vehicle-pedestrian conflicts after LPI changes were made at the intersections (see 2022 research paper and Jacobs report). Because of the favorable study results, starting in 2022 Bellevue is expanding the use of LPIs throughout its downtown area.

Working with Transoft Solutions, Together for Safer Roads, and PacTrans – University of Washington, the city completed a first-of-its-kind citywide analysis of traffic camera video in support of Vision Zero. For information on this collaboration see:

This strategic partnership with Transoft Solutions (ITS)—formalized in 2019—is a continuation of work that commenced with Microsoft (see 2016 brochure and 2019 case study). Information on the previous partnership is available in an ITE Journal article, in an overview video (April 2017) and in a video about potential applications (August 2018).

Another company, Street Simplified, assisted the City of Bellevue with a pilot project that used video analytics to evaluate safety at the intersection of 108th Avenue NE and Main Street (see case study).

Data Partnerships

Bellevue is committed to collecting and analyzing data to understand the factors that impact the safety of our transportation system and leverage this insight to identify improvements and evaluate outcomes.

As part of its Safety Data Initiative, the US Department Transportation and Volpe Center collaborated with the City of Bellevue in piloting local safety applications of Waze data (see case study and WIRED Magazine story).
