Integrated Traffic Control Systems (ITCS)

Unified control by analyzing and utilizing collected data creates optimal road traffic conditions.

ITCS is a large-scale traffic management system that achieves safe and smooth road traffic. This system realizes optimal traffic management for cities and environment by providing traffic information via various media and controlling signals based on the result of traffic information analysis collected by detectors on roads.

Sumitomo Electric provides a wide range of products, from detectors, signal controllers, central devices, to data transmission devices. These products are adopted in many facilities across the country including the Metropolitan Tokyo Traffic Control Center, the Japanese largest traffic control center.

Signal Control Algorithm

Signal Control Algorithm "MODERATO-S" realizes optimal signal control to minimize waiting time at intersections with the collaboration of "macro control" which controls the overall road network by the central device of traffic control centers, and "micro control" which is processed by each traffic signal installed at intersections.

Macro Control

It determines the optimal signal control parameter depending on changes in the traffic situations measured, and it eliminates the need for signal control parameter design which requires specialized technologies.

Micro Control (Demand Prediction Control)

In order to respond to random changes in traffic flow, it predicts the status of changes in the flow from current to a few minutes ahead of the future based on the information observed at upstream of its flow. The operation realizes optimal signal controls without any delay.
