O-D matrices, Steady-state traffic counts information, Area Traffic Control System, Real-time traffic count information


Abstract:

The conventional method to estimate O-D matrices requires very large surveys such as : home and roadside interviews; which are very expensive, labor intensive, and subject to large errors. Previous researches have been able to obtain the O-D matrices by using steady-state traffic counts information. ATCS (Area Traffic Control System) already installed in Bandung since 1997 provides us the realptime traffic count information for all signalized intersections. The technology for transferring data via internet is also available and at a very low cost. The paper will explain the dynamic phenomena in estimating the O-D matrices in a real-time basis based on real-time count information. This model can be used to study the day-to-day evolution of the O-D matrix relating to traffic flow fluctuation. Having known the real-time O-D matrix, several analysis and applications in a real-time basis can be conducted for solving urban transportation problems.
