Smart signals in Bengaluru help to increase traffic speed to 15 kmph, cut travel time

According to the data, prominent corridors benefiting from the AI-powered intervention include JC Road, KR Road, BTM Layout, Sarakki Main Road, Bannerghatta Road, Outer Ring Road-JP Nagar and the Jayanagar corridor. JC Road, known for major bottlenecks, saw the most remarkable improvement with average speeds jumping 61 per cent from 4.87 kmph to 7.82 kmph. Similarly, BTM Layout recorded an improvement in traffic speed by 43 per cent, Hosur Road by 48 per cent, and Jayanagar by 34 per cent.

The data also highlighted that smart signals along the length of 35.2 km have contributed to combined fuel cost savings to Rs 9,000 per 1,000 vehicles.

How is the performance evaluation carried out?

M N Anucheth, Joint Commissioner of Police (Traffic), explains that a detailed pre-installation travel time study is conducted for all ATCS corridors by driving along the corridor using a GPS-enabled application. “This application records critical trip details such as the origin, destination, travel time, speed and other relevant data. The study is carried out during both peak and off-peak periods to capture the variability in traffic conditions. Once the ATCS system becomes operational, a similar study is conducted to measure post-installation travel times under comparable conditions,” he said.

Additionally, to continuously monitor and evaluate the system’s performance, travel time data is periodically captured along these corridors using map-based services. These measurements are taken at regular intervals during both peak and off-peak periods, ensuring a comprehensive assessment of the system’s impact on travel efficiency over time, said Anucheth.

Which are the areas where ATCS has been successful?

Among the corridors where the ATCS has been implemented, the KR Road and Minerva-JC Road corridors have demonstrated consistent performance improvements exceeding 20 per cent. This improvement is attributed to effective coordination facilitated by the ATCS, enabling smooth traffic progression and reducing delays.

In the KR Road corridor, coordination has been established to create a “green wave” for vehicles travelling from National College Junction to Medical College. Similarly, in the Minerva-JC Road corridor, vehicles benefit from coordinated signals, ensuring minimal stops as they move from Minerva Circle to JC Road Junction. This synchronisation allows a majority of vehicles to receive green signals at successive junctions, promoting seamless movement and reducing travel times, analysis by the traffic police department shows.
