DRIVING IN DELHI – Sensors to cut wait at traffic signals

March 20th, 2007

WAITING AT traffic signals, while driving, for the red light to turn green can be irritating – especially if the roads are empty The Delhi Traffic Police now plan to shorten your wait. They will plant sensors in the roads near intersections to regulate traffic signals according to the volume of traffic, a senior officer told HT “These sensors will be placed 50-100 metres from the intersection, embedded two inches under the road,” said Qamar Ahmed, joint commissioner of police (traffic).

“The sensors will catch the number of vehicles approaching the intersection. Accordingly, the timing of the traffic light will be controlled.” The sensors will be installed at 20 intersections soon. With the sensors in place, the traffic police also hope to see a decrease in red-light jumping. According to their records, prosecution for jumping redlights increased by 6.48 per cent in 2006. “Red-light jumping usually happens late at night or early in the morning when there is less traffic.

With waiting time reduced, there might be less of it,” said another officer Some traffic experts, however, said pedestrians should be kept in mind when such measures are taken. “The technology is good for off-peak hours. But during peak hours the volume is high,” said Geetam Tewari of the Transport Research and Injury Prevention Programme, HT Delhi. “The optimum waiting time is 180 seconds, which suits motorists as well as the pedestrians. This might not be suitable for pedestrians who wn have to wait longer at crossings at peak hours.” But there are others like EK. Sarkar, head of department (transport planning), School of Planning and Architecture, who said the sensors should be tried out. “Such a move should not be discouraged,” said Sarkar, adding that such sensors are used in the UK.
