Using Visualization for the Design Process of Rural Roads
نویسندگان
چکیده
The three-dimensional image of a road, which gives drivers all the important information for driving, is only obtained when three design levels are superimposed. If design engineers do not follow current standards during this complex process, shortcomings may occur and effect road safety. That’s why during the classical road design process he must check the three-dimensional alignment with the aid of perspective images. In order to be able to avoid shortcomings it is necessary to develop a new methodology of road design by using special three-dimensional design elements. The three-dimensional design can consist of fixed dialogue and coupling elements. The three-dimensional course of the route is visually represented using a real time simulation and the three-dimensional image can be checked by stereoscopic techniques.

Vehicle crashes are amongst the major causes of mortality and results in losses of lives and properties. A large number of the vehicle crashes occur on rural roads. Accidents become more noteworthy in two-lane roads due to going and coming traffic. Therefore, prediction of crashes and their causes are considerably important to reduce the number and severity of the accidents. The safety index is...

One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the accident cause makes the selection of high accident prone segments inaccurate. In this paper, by...

Safety analysis of the roads through the accident rates which is one of the widely used tools has been resulted from the direct exposure method which is based on the ratio of the vehicle-kilometers traveled and vehicle-travel time. However, due to some fundamental flaws in its theories and difficulties in gaining access to the data required such as traffic volume, distance and duration of the t...

Research into advanced traveler information systems (ATIS) for rural roads is limited. However, highway agencies expect to implement intelligent transportation systems (ITS) in both urban and rural areas. In this paper, genetic algorithms (GAs) are used to design both time delay neural network (TDNN) models as well as locally weighted regression (LWR) models to predict shortterm traffic for two...
