INTERURBAN ROADS AND MOTORWAYS. REPORT FROM CZECHOSLOVAKIA --PIARC XVIII WORLD ROAD CONGRESS, BRUSSELS, BELGIUM, SEPTEMBER 13-19, 1987

This report summarises research activities in Czechoslovakia in the following areas: (1) development of traffic modelling of the czech highway network 1982-1985; modifications to the gravity model and its supplement with regional analysis. Determination of future highway traffic volumes in the slovak territory according to the planned development of the national economy and of society; (2) method of assessing road construction impacts on the overall energy requirements of road traffic in the construction and operation stages of new highways (maintenance, repairs). How energy requirement indices supplement the assessment of the overall economic efficiency of road construction; (3) development of computer-aided design of roads and bridges in Czechoslovakia. The dialogue system accelerates and improves the quality of the designer's work. Software consists of packages of interconnected programs; hardware is on the developed basis of mutually compatible computers with printer and graphic outputs; (4) development of an information and management system -the road data bank in Czechoslovakia. On the basis of a node location system, the data bank is concerned with the basic administrative, geometric and structural data as well as the characteristics and condition of pavements, traffic volumes, and accident rates; (5) in the framework of the TEM (trans-european motorway) project, Czechoslovakia has prepared draft guidelines for the ecological optimization of highway routes. On the basis of validation on practical examples, the final version of the guidelines is nearing completion; (6) more severe criteria for the assessment of the environmental impact of road construction (noise, air and water pollution) are being introduced; (7) the effect of traffic emissions on the highway environment; the results of measurements of harmful substances in fruit, grass, soil; recommendations for the planting of roadside flora; (8) reduction of accident rates on the highways in the cssr 1976-1984; introduction of speed limits in 1979, analysis of development and partial results. Model of assessment of skid resistance of road surfaces; (9) modification of design standards to improve the economics of road construction.(a) for the covering abstracts of the congress see IRRD 812115 and 812116.
