A SPaT Data Transmission Latency Analysis Compared DSRC Links Having Shorter Range and Low Latency (Less Than 2 Milliseconds) Against Cellular Links Having Longer Range and Higher Latency (Greater Than 40 Milliseconds).
SPaT data were collected at three separate intersections within the VCC, including a 4-way intersection in a dense area, a T-type intersection near a small shopping center, a major arterial, and a…
