Prediction of Safety Opportunities Using Automated Traffic Signal Performance Measures

A variety of low-cost safety improvements are possible at signalized intersections such as implementing no right turn on red, leading pedestrian intervals (LPI), and conversion of permitted left turns to protected left turns. However, resources (both time and money) are limited, so intersections need to be prioritized for these improvements. Additionally, each improvement targets a particular safety concern. Currently, studies with traditional data are used to evaluate safety concerns at signalized intersections and propose recommended improvements. This approach is time consuming and requires extensive data collection and evaluation. Automated Traffic Signal Performance Measures (ATSPM) data could be used as an alternative to traditional data collection and allow for a widespread evaluation of many signals. ATSPM data can also be used in a dashboard system that evaluates change over time and alerts operators to changes in the field that may affect safety
