We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
