Utilizing Ego-centric Video to Conduct Naturalistic Bicycling Studies

Feng Liu
Miguel Figliozzi , Wu-chi Feng
Bicycling is enjoying a surge in popularity across the USA but bicycle safety continues to remain a challenge. Cyclists (and pedestrians) are the most vulnerable road users since cyclist-vehicle collisions often result in severe injuries and have high fatality rates with respect to other types of collisions. In particular, intersections are one of the most critical areas in a road network given the high number of conflicts and accidents occurring at these locations. Although there has bee... Read More

Exploiting New Data Sources to Quantify Arterial Congestion and Performance Measures at a Regional Scale

Miguel Figliozzi
Robert Bertini
Most urban vehicle miles traveled take place along arterials and collector streets. Arterials and collector streets are also essential to provide accessibility and provide mobility for public transportation fleets; these roadways constitute the backbone of bus routes in urban areas. However, unlike freeways, arterials and collectors are still relatively understudied and do not have a large body of work related to congestion quantification and performance measures (PMs). This proposal is time... Read More
