Ground-breaking study demonstrates traffic-cam monitoring is effective way to improve road safety

Written by: Keysoft Solutions

Keysoft Solutions Ltd is excited to announce the results of a year-long working partnership between parent company Transoft Solutions Inc., and the City of Bellevue, Washington and the Together for Safer Roads coalition. The project, formally titled “Video-based Network-wide Conflict and Speed Analysis to Support Vision Zero in Bellevue (WA) United States” is the first-of-its kind, citywide analysis of traffic camera video with the goal of improving safety for all road users.

Over 5,000 hours of video from Bellevue's network of cameras were analyzed using Transoft Solutions' BriskLUMINA and BriskVANTAGE software. The video footage, which included traffic volumes, road user speeds, and near-crash traffic conflict indicators, was used to produce three reports: 1) Video-based Network-wide Conflict Analysis 2) Video-based Network-wide Speed and Speeding Analysis and 3) Video-based Conflict, Speeding, and Crash Correlation.

Using the results from these reports, the project showed that intersection conflicts, or near-crash events, were an accurate predictor of where future crashes could occur. Other significant findings from the reports also include:

  • While cyclists make up less than 1% of road users, they are 10 times more likely to be involved in near miss collisions than motorists.
  • Motorcyclists travelled at higher speeds and generated more critical conflicts than any other road user.
  • More than 10% of drivers were found speeding, and half were more than 11 miles per hour over the speed limit.

The Vision Zero program is a strategy to end roadway fatalities and severe injuries by the year 2030. The project came about from the City of Bellevue’s own Vision Zero initiatives which coincided with Transoft Solutions’ road safety analysis technology and the non-profit, Together for Safer Roads innovative coalition to bring together organizations to collaborate on improving road safety.
