For decades, transportation has been considered as a link to all aspects of life worldwide. In this case, the world’s natural environment,social well-being and economic development all usually depend on transportation systems. In most cases, safe, clean, sustainable and equitable transport systems help countries, especially in cities and urban centers, to thrive. Growth in urban centers makes mobility a challenging issue. Roads are long-term infrastructure assets. The first problem is, once built, it is very costly and disruptive to widen or redirect them, especially in inner-city areas, which has a limited capacity. This requires sustainable traffic management to enhance overall readily traffic flow. Traffic signal timing plays a pivotal role in the management of sustainable urban traffic in densely populated urban areas. It offers a potential to prevent traffic accidents and improve mobility of the transportation network by alternatively allocating right of way. The design of traffic signal timing parameters,such as green time ratio, can significantly affect the operational efficiency, travelling time plus travelling cost, the safety of intersections and the total amount of traffic emissions in the network.The second problem is, from time to time whenever an accident happens, sometimes from transgressors of speed, the traffic will be so massive that it comes to a total halt, which is longer than usual. This can also be attributed to the fact that the traffic light system is not smart enough to inform the traffic management and react to the situation to ease the congestion. It is, therefore, crucial for us to design the traffic signal timing parameters carefully and compatibly with a smart system, so as to create a safe, efficient, and sustainable urban transportation system, particularly in an era of climate change.
