Midtown Virginia St. BRT Post Study Analysis
Collected trajectory data from roadside LiDAR sensors at 18 sites along 1.2 miles of a newly reconstructed complete street in a commercial area for purposes of analyzing safety and operations.
Virginia St goes through the heart of the City of Reno, NV, through the University of Nevada, Reno, downtown and the bustling midtown region, and beyond. S Virginia St dissects the heart of the midtown region and offers access to many shops and restaurants that the region has to offer.
Recently, the S Virginia St arterial through midtown was reconstructed to add bus rapid transit (BRT) and add complete street elements such as extended sidewalks, more crosswalks with bulb outs, and restricted access through raised medians, and a new roundabout to name a few.
Upon completion of the construction, it was desired to see how the new infrastructure affected safety and operations of the arterial. As such, Roadside LiDAR data was collected at 18 sites spanning 1.2 miles at an effective detection range of 300 feet in radius, which covers a large majority of the study area. Trajectory data was generated for the purposes of studying the safety and operations of the arterial.
The traffic safety performance includes generating near misses – or conflict events - through post-encroachment time (PET), road users crossing distance measures, and deceleration. Other safety measures generated include vehicle speeds, vehicle-pedestrian yield rates at uncontrolled crosswalks, and non compliance events such as wrong-way driving, illegal maneuvers, and jay-walking. For operational performance, vehicle delay, queue lengths, and multi-modal traffic counts are generated.
