Road traffic simulation apparatus
First Claim
1. A road traffic simulation apparatus for simulating road traffic produced by a road traffic environment and a plurality of moving objects, the apparatus comprising:
- one or more moving object models, each including a driver model and a vehicle dynamics model; and
a traffic environment database;
wherein said moving object model of a subject moving object uses a travel difficulty for unitary indicating a state of traffic around the subject moving object, said state of traffic including traffic environment around the subject moving object and traffic situations involving other moving objects around the subject moving object.

Abstract
A technique for simulating natural behaviors of moving objects is provided. A road traffic simulation apparatus includes a simulation unit for performing a traffic simulation, a display unit for displaying a progress status of the traffic simulation and a control unit for controlling the simulation unit. The simulation unit has a traffic environment database and a moving object model. The moving object model has a driver model in which a driving operation of a driver is modeled and a vehicle dynamics model in which a vehicle behavior is modeled. The driver model performs different processes in parallel in respective different cycles. The results of each cycle process are integrated and output to the vehicle dynamics model.
