In an effort to improve the traffic systems, the Kerala Road Safety Authority (KSRA) has completed the first phase of installation of high-tech automatic traffic enforcement systems on the 98 km Edappally-Mannuthy stretch of NH 544. As part of the Rs 8.5  crore project, 65 automatic traffic enforcement systems will be installed at 23 points on the stretch. The monitoring technology involves a mixture of virtual sensors, motion detectors, inductive sensors, logo sensors and high resolution cameras. Pictures of number plates would be captured using 10 megapixel cameras. The main server that will be linked to all cameras will be set up at the deputy transport commissioner's office. The magnetic sensors installed on roads will trigger the cameras in case of violations and send a message to the main server. Offenders will be traced based on visuals of vehicles and registration  plates and they will be issued notice. The project is being implemented by KSRA and the Motor Vehicles Department with the technical support of Keltron as part of the decision to observe 2011-2020 as the 'decade of action for road safety'.
