REAL-TIME TRAFFIC ANALYSIS THROUGH INTEGRATION OF ROAD TRAFFIC PREDICTION AND TRAFFIC MICROSIMULATION MODELS
First Claim
1. A system for forecasting a vehicle traffic condition in a near future, the system comprising:
- a traffic prediction tool for estimating traffic data including;
a traffic speed and volume in a traffic link, the traffic link referring to a portion of a traffic road where the traffic prediction tool is installed;
a turning percentage prediction module for receiving the estimated traffic data and estimating a turning percentage in the traffic link based on the estimated traffic data; and
a simulation tool for computing, based on the estimated turning percentage and the estimated traffic data, an expected traffic volume in the traffic link,wherein one or more of the traffic prediction tool, the turning percentage prediction module and simulation tool is implemented in a computing system that comprises at least one processor and at least one memory device connected to the processor.

Abstract
A system, method and computer program product for forecasting a vehicle traffic condition in a near future. The system comprises a traffic prediction tool, a turning percentage prediction module and a simulation tool. The traffic prediction tool estimates a traffic speed and volume in a traffic link. A traffic link refers to a portion of a traffic road where the traffic prediction tool is installed. The turning percentage prediction module estimates a turning percentage in the traffic link based on the estimated traffic speed and traffic volume. The simulation tool computes, based on the estimated turning percentage, the estimated traffic speed and the estimated traffic volume, an expected traffic volume in the traffic link.
