Smart Traffic Management System

Technology #11396s-fm

Market Opportunity

Traffic congestion is an increasing problem in major cities around the world and there is a sizeable market for better traffic management systems. Most major cities currently employ adaptive traffic signal control systems where the light timing is adjusted based on the current traffic situation. However, one of the major drawbacks of these approaches is the scalability issue. In addition, popular existing solutions like SCATS and SCOOT use loop detectors that require high installation and maintenance costs and are not adequate to address the traffic complexity today.

Hence, there is a need for more investments toward developing systems that can predict traffic behavior from data collected by traffic sensors and scale well.


Researchers from the Future Urban Mobility Group, an interdisciplinary research group under the Singapore-MIT Alliance for Research and Technology (SMART) Centre and supported by the National Research Foundation (NRF) Sinagpore, have developed a smart traffic management system that uses vehicular location information in real-time to determine queue length. This work is motivated by the backpressure routing algorithm that is used mainly in communication and power networks.

Stage of Development

Under the Jurong Lake District (JLD) project for smart traffic system management, ST Electronics implemented a traffic model to evaluate the performance of the algorithm. STE has submitted a proposal to LTA for Phase 2 of the project which will involve field trials.


The invention can be used in urban traffic management to reduce congestion and maximize throughput at traffic junctions. It can be applied universally across all traffic signal controllers


  1. Requires minimal tuning and scales well with the size of the road network while ensuring satisfactory performance.
  2. Its performance is an order of magnitude better than the currently widely implemented  SCATS system.


Patent granted in the US and pending in Europe, China and Singapore.
