LTA Employs Innovation in Traffic Forecasting

Motorists can look forward to more reliable traffic advisory information in the future, thanks to the Traffic Prediction Tool (TPT). TPT is a technological tool currently used by the Land Transport Authority (LTA) to anticipate and manage traffic flow so as to minimise traffic congestion.

The LTA has been working closely with IBM since 2006 to develop the TPT for local conditions. A patent-pending technology, the TPT can currently achieve up to 85% accuracy in predicting traffic volume and speed 10 minutes ahead, based on the work done in an earlier phase involving roads in the Central Business District from December 2006 to April 2007.

TPT predicts traffic speeds and flow using advanced statistical techniques. It relies on both real-time and historical data to generate its predictions.

Presently, data on the traffic volume and speed is collected and fed to the TPT through other Intelligent Transport Systems such as the EMAS, GLIDE, J- Eyes and Traffic Scan.

Phase 1 of TPT has already been completed. Subsequent phases will involve more research and development to improve TPT's prediction, particularly for roads where coverage by sensors are less comprehensive, and hence, traffic data is still being obtained.

The TPT is part of LTA's wider effort to employ innovation not just to improve its traffic management capabilities but also to enhance its business processes and customer satisfaction.
