An Intelligent System for Traffic Control in Smart Cities

Traffic congestion is a severe problem in many major cities across the world and it has become a nightmare for the commuters in these cities. Conventional traffic light system is based on fixed time concept allotted to each side of the junction which cannot be varied as per varying traffic density. Junction timings allotted are fixed. Sometimes higher traffic density at one side of the junction demands longer green time as compared to standard allotted time. The suggested case study, Jakpa junction, Delta State, Nigeria is a typical example of a traffic congested area. The junction is a link to three roads which include; Effurun-Sapele road, Jakpa road, and PTI road. The conventional traffic light system based on fixed time is employed to control the traffic in this area. But the system only increases the level of traffic congestion during peak hours. As a result of this a lot of time is wasted in the process. Therefore, this book examines a density based approach for control of vehicular traffic. The signal timing changes automatically on sensing the traffic density at the junction.
