Traf­fic cops ask NMMC for sen­sor- based traf­fic sig­nals

NAVI MUM­BAI: In a move to counter the grow­ing traf­fic snarls in the city, the traf­fic po­lice de­part­ment has sent a let­ter to the Navi Mum­bai Mu­nic­i­pal Cor­po­ra­tion (NMMC) re­quest­ing them to re­place the ex­ist­ing man­ual sig­nals into sen­sor­based traf­fic sig­nals.

A sen­sor-based traf­fic sig­nal is a den­sity based dy­namic traf­fic sig­nal sys­tem.

Un­like the con­ven­tional traf­fic sig­nals, which al­low traf­fic move­ment at each side of the junc­tion for a fixed time, the sen­sor-based sig­nals con­stantly keep sens­ing the den­sity of traf­fic on all sides of the junc­tion and send real-time feeds to the con­trol room.

Of­fi­cials said if the sys­tem is im­ple­mented, traf­fic con­ges­tions in the city can be eased and man­aged bet­ter.

“There are con­tin­u­ous traf­fic con­ges­tions in sev­eral parts of the city, es­pe­cially those where the heavy ve­hi­cles ply. With the present traf­fic man­age­ment sys­tem it is not pos­si­ble to ease the traf­fic as the ve­hi­cles have to wait for the al­lot­ted time of 30 or 60 sec­onds,” said Arvind Salve, deputy com­mis­sioner of po­lice, traf­fic de­part­ment of Navi Mum­bai.

In the sen­sor-based sys­tem, if the traf­fic den­sity is high on a par­tic­u­lar side, pri­or­ity is given to that side.

Traf­fic of­fi­cials said they re­ceive reg­u­lar com­plaints of traf­fic jams on their helpline num­ber and twit­ter ac­count. How­ever ow­ing to the present staff crunch, it was not fea­si­ble to de­ploy traf­fic con­sta­bles at each and ev­ery junc­tion.

“If the sys­tem is more reg­u­larised, we can de­ploy our staff in the in­ner roads near schools and hos­pi­tals which do not have sig­nals,” said an of­fi­cial from the Be­la­pur traf­fic of­fice.

There are 40 sig­nals un­der the NMMC ju­ris­dic­tion. Of­fi­cials from the civic body said they have re­ceived the pro­posal.

“The pro­posal is cur­rently un­der dis­cus­sion. We want the tech­nol­ogy to be cost-ef­fec­tive and run ef­fi­ciently in con­trol­ling the traf­fic with­out any glitches. The cost of the in­stal­la­tion, re­pair and main­te­nance should also be shared by the city po­lice,” said Di­nesh Wagh­mare, mu­nic­i­pal com­mis­sioner.
