摘要

A connected vehicle traffic safety system (10) comprises a traffic signal controller (75) and a roadside unit (RSU) (30) located at a one-way traffic lane (72) for avoiding crashes with vehicles of wrong-way drivers by issuing warnings for wrong-way violations. The traffic signal controller (75) is configured to operate a traffic signal (80(1)). The traffic signal (80(1)) is facing a wrong-way traffic (96) and is set to dwell permanently in a RED signal phase (98). The one-way traffic lane (72) is configured as a signalized intersection with a wrong-way approach (127(2)) that is programmed as a traffic signal phase dwelling in RED. The roadside unit (RSU) (30) is configured to transmit a Signal Phase and Timing (SPaT) indication for the RED signal phase (122). A first Onboard Unit (OBU)-equipped vehicle (15) having an Onboard Unit (OBU) (35) that is configured to calculate a RED light violation (135) based on at least one of vehicle location data (105), direction heading data (110), and speed data (115) provided from the first OBU-equipped vehicle (15) and the SPaT indication of the RED signal phase (122) to detect the first Onboard Unit (OBU)-equipped vehicle (15) as a wrong-way vehicle.
