data highway
5.On surveying step, Leica TC 1610 Total station will be used to survey angle,setup center stake and survey elevation. After surveying finish, the surveying data will be stored in REC module. On design step,data in the module will be conversed into the data on ve rtical sections and surface of highway,then the data will be used in highway design.
7.DESIGN AND IMPLEMENTATION OF BI-WAY TALKING SYSTEM BASED ON HIGHWAY DATA NET
8.Based on the statistical data of road traffic accidents, population, number of vehicles, total lengths of highway, passenger and freight transport amount of 1990-2000 in China, it is known that the freight transport amount, freight turnovers and passenger transport amount are the main con-elated factors influencing the traffic safety, and number of casualty is the main characteristic and indicator of toad traffic accidents.
9.Based on investigations on highway construction projects in Chongqin City and Guizhou Province,the environment impact characteristics of highway constructions were analyzed.Some shortages in EIA and environmental management were analyzed and several new environment management opinions were put forward:1.carring out dynamic management with whole procedure of highway construction; 2.paying attention to separating effect to wild animals,landscape resources conservation,environment supervision during construction period,ecological benefit,and providing more environmental data; 3.handling the envionmental problems with new techniques in the expressway construction; 4.broadening the knowledge in environment of highway workers and environmental managers and raising the level of education.
