DRIVERS' RISK PERCEPTION OF ROAD DESIGN ELEMENTS
New roads are often designed without adequate investigation of driver risk perception. However, according to many researchers, it is imperative that human factors be considered during the design of new road infrastructure. In this study we investigated driver perception of risk on 3 road sections of a single highway. For the purposes of this article, 3 field experiments took place in a 2-year period, with 136 volunteer Greek drivers taking part in these experiments. Participants evaluated the risks of road sections and curves. The results show that 3 main demographic characteristics-age, familiarity, and self-assessment-affect risk perception, whereas special provisions for older drivers during road design and construction are imperative.
The article introduces the airport pavement structure performance test that based on HWD test data.Combined with one HWD test result in an airport in eastern China,the article discusses the parameter inversion principle and performance evaluation index and procedure of the complex pavement,and also analyzes the parameter inversion principle,ACN-PCN strength evaluation,structure lifespan,structure adaptability thickness and other evaluation index.
