  • Chris Svolopoulos, MSCE, EIT, Associate Civil Engineer| Seattle Department of Transportation

    Chris is an Associate Civil Engineer in Seattle DOT’s Vision Zero group. There, he is involved in multiple programs related to the reduction of severe and fatal traffic collision incidents in the City of Seattle. As part of this effort, Chris manages the Bicycle and Pedestrian Safety Analysis (BPSA), a proactive, multivariate data project that evaluates how roadway and signal design influences bicycle and pedestrian collisions in the City’s public roadways. The most recent iteration of the BPSA includes video analysis of varying protected bicycle lane designs and configurations at intersections to evaluate near-misses, road user behavior modification, and efficacy of engineering standards on reducing conflict rates. The results of the BPSA are used to model Safety Performance Functions for multiple collision types throughout the city and inform engineering efforts to help address potential bicycle and pedestrian collision trends before they develop.

  • Paul G. St-Aubin, P.Eng., Ph.D., Head of ITS| Transoft Solutions

    Dr. St-Aubin holds a Bachelor’s and Master’s in Civil Engineering, a Ph.D. in Civil Engineering, and completed a postdoc at HEC Montreal and the Institute for Data Valorisation. Paul has over a decade of experience practicing road safety consulting, including for the cities of New York and Montreal, as well as the Quebec Ministry of Transport. He has taught several traffic engineering courses and has extensive experience developing, deploying, and overseeing large-scale proactive road safety technology projects, including recent cutting-edge work in predictive collision course modelling. Paul specializes in several civil engineering and computer science topics, including road and safety design, driver behaviour, advanced collision detection, traffic control devices, vehicle automation, traffic data collection systems, computer vision, ITS, traffic microsimulation, and software architecture.
