Abstract
The role of guide sign to inform road users about the information of network is important. How to design and locate guide sign to increase traffic operation efficiency is a key point for traffic engineers. Driving simulator is useful device to study guide sign. Guide sign’s validity in driving simulator was studied. Results of this experiment are the foundation of further study on guide sign. Simulator calibration procedure for guide sign was set up in this study. Legibility distance as measure of performance was used to evaluate the validity of guide sign in driving simulator. Thirty two participants were recruited. Results indicated legibility distance and speed was inversely related. Legibility distance and text height of guide sign was positive related. When speed is 20km/h, 30km/h, 40km/h, magnifying power of text height is 4.3, 4.1, 3.8, while guide signs are absolute validity in driving simulator.
Highlights
Study in Simulator conducted in driving simulator mainly focus on road safety treatments evaluation [1], variable message sign [2], driver’s capability [3], road landscape design [4], and so on
The results indicated that differences between the speeds observed in the real situation and those measured with the simulator were not statistically significant, which demonstrated driving simulator in absolute terms
This study aims at investigating the guide sign’s validity in driving simulator
Summary
Study in Simulator conducted in driving simulator mainly focus on road safety treatments evaluation [1], variable message sign [2], driver’s capability [3], road landscape design [4], and so on. Driving simulators have become an increasingly widespread tool to study problem in transportation area. With the remarkable development of electronic and computer technology, simulator technologies are being rapidly enhanced. Driving simulators have many merits such as simplified factors, easy-to-detection data, safety, repeatability and cost-effective.
