Design of 3D Virtual Simulation and Evaluation System for Road Traffic Signs

A three-dimensional (3D) virtual simulation system was developed in this paper for reappearance of the visibility and validation of road traffic signs. The system combined subjective and objective evaluation methods to reconstruct and optimize traffic signs design. Based on the system perspective of driver-vehicles-road, a 3D interactive simulation model was proposed and developed, including driver functional model, vehicle type select model, vehicle generation model, 3D road scene, and road network building model. This system has solved the shortages of static testing method and the complicated problems of dynamic testing method. And this system has provided a straight forward and reliable on-line analysis and simulation platform for pre-design, post-optimization and transformation work for road traffic signs system.
