|Project Title:||A Multi sensor platform for predictive analytics and real time junction traffic signal control|
|Hosting Institution:||LSCM R&D Centre (LSCM)|
|Abstract:||Hong Kong roads are busy, handling tens of millions of passenger trips and cargo transfers a day. This level of mobility has been maintained by continuous construction and improvement of rail and road infrastructure. However, land constraint somehow limits the impact of these infrastructure expansion and improvement. Thus, technologies play an important role. On the use of technologies, Transport Department in Hong Kong has deployed many systems on the road for traffic management. Since their exploration in a computerized Area Traffic Control (ATC) 40 years ago, they have developed Journey Time Indication System (JTIS), Speed Map Panels (SMPs), Traffic Control and Surveillance System (TCSS), Traffic and Incidence Management System (TIMS), and Mobility Mobile App (HKeMobility) to enhance the efficiency of traffic management.
Recent deployment by Transport Department would have been the smart traffic lights system at Tai Tam Road (Dam Section). This system is first in Hong Kong applying Video Analytics for real-time traffic signal control.
Many these systems have been in operation. Traffic data are separately collected through multiple data sources using cams and loop detectors, etc. These data may be appropriately collected for their associated local applications and systems. They are never used to help make intelligent decisions and actions in a bigger area for increasing traffic efficiency, mediating traffic jams, and improving road safety. In order to maximize the value of these traffic data, we need to stream real-time traffic data from various collection sources to a platform for predictive analytics and real-time junction signal control.
This project leverages on the previous experience of the first smart junction traffic control in Hong Kong: Real time control of the green time of traffic light in Tam Tai (Dam Section) and push button control in Broadwood Road / Link Road Junction. Different from these pervious projects, this work is concerned with traffic flow in a bigger district.
