Traffic Operation and Safety Analysis on an Arterial Highway: Implications for Connected Vehicle Applications

This paper presents the operational and safety analysis of an arterial highway establishing benchmarks before deploying connected vehicle (CV) technologies. This is especially critical for the safety of at-risk populations such as older adults. The study corridor is on US 90 located in Tallahassee, Florida. Two operational performance measures were used in the analysis which are travel time reliability and delay. For the safety analysis, crash topology and the level of safety benefits likely to accrue in the study corridor due to the implementation of CV applications and automatic traffic signal performance measures were assessed by predicting the likelihood of crash reduction by type based on the preponderance of literature review.
