Urban Transport Safety Improvement Based on Centralized Traffic Control System, Colombian Case Study

Open access


In a modern urban organization, mobility is an important issue for society. Traffic congestion of urban roads undermines mobility is a real problem in major cities This article shows the development and implementation of a centralized traffic control system in the city of Cali Valle (Colombia) applied to control traffic lights located to the east of the city (Simon Bolivar and Ciudad de Cali highways), allowing the central operators directly influence the traffic flow, know and display the status of the lights and generate statistics about the events of the online equipment. Particular real benefits of proposed new system of traffic lights are reflected in green times at each intersection allocated in accordance with the present traffic volumes on the road network at any time of day and in every sector of the city in particular, which of course increases the efficiency of each light installed at each intersection. As demonstrated in this article case study, the congestion scheme has been improved, and the project has opened up vast opportunities for innovative network management strategies for the optimization of network performance. Many of these strategies are developed to give a coordinated high-level control across different traffic control platforms based on real time traffic condition and performance on site.
