BTRAC – smart signals are coming

Hope you still remember BTRAC-2010, the nice sounding traffic management project for Bangalore. Seems like KRDCL has started the process of putting up new traffic signals under this project. This bidding document talks of 204 locations for these signals. Thankfully, this document contains the specifications of these new signals as well, and they do seem smart – vehicle detectors, remote control from a Traffic Management Center, pedestrian crossings with audible alarms, and more. Have a look:

The new system shall comprise of outstation units (OU) at each intersection and an in-station unit (IU) located at the Traffic Management Center (TMC) in Bangalore city. Out station unit at any intersection shall comprise of a Vehicle Actuated Signal Controller with backup power resourses, vehicle detector and detector module, polycarbonate vehicle and pedestrian signal lamp heads with LED lamps, countdown timers, audible alarm, interconnecting cables, an appropriate interface to connect the OU with IU through a wireless or wired communication system. The in-station unit shall comprise of servers, a workstation, communication system and an operating system

Read section 4 of that document if you are curious for more. The list of 204 proposed locations is in there as well.

If implemented well, these 10 crore rupees would be worth more than a few of those instant flyovers. Anyone disagrees? Synchronized signals help much more than flyovers. Flyovers on city roads, in fact, complicate matters by creating thicker and fewer chunks of traffic.

Now, some trivia for you. As per the BTRAC website, there are 40000 intersections in Bangalore, and only 167 of them are signalized!
