Traffic flow data collection device and traffic flow data collection method

摘要

PROBLEM TO BE SOLVED: To measure traffic flow data at an intersection used for determination of a traffic situation at the intersection, on the basis of a detection result of a vehicle in the intersection.SOLUTION: A vehicle detector 1 detects the presence/absence of a vehicle located in detection regions 101-108 set in an intersection in association with inflow passages 111-118 of the intersection in which a signal lamp is installed, and, on the basis of the detection result, generates a vehicle detection signal indicating whether a vehicle located in the detection regions has been detected. A signal controller 2 processes the generated vehicle detection signal, and performs the measurement related to the occupancy of the detection regions and the measurement related to the traffic flow rate in the detection regions.SELECTED DRAWING: Figure 1
