Between 1970 and 1981 the total mileage of all vehicles in the Federal Republic of Germany increased by 38%, at the same time the length of the total road surface only grew by 10%. The average traffic density has increased. Effects: longer driving time, increased fuel consumption and consequently an increased burden on economy. Apart from an extension of the road net which is not always possible, the traffic flow can be improved by optimising the existing road net. During the investigations described here the new draft for the 'Directives for road construction, Part: Investigating the economy' was screened, the functions used were adapted and the data were brought up to date. Based on this approach concrete road construction measures were carefully investigated. Comprehensive cost-analyses took into account not only the savings for the national economy by reduced fuel consumption by also the shorter driving time and reduced staff cost. In the case studies made here it was possible to indicate the profitability limit for the respective road construction measures depending on traffic density. Result: economically reasonable extensions of the road net of the Federal Republic of Germany have an energy saving potential of about 1 million tons of fuel/year and costs of 1,8 thousand million DM. These possibilities of optimising our road net should be used in the interest of our economy. (ERA citation 10:025765)
