Aiming at the disadvantages of traditional design method of highway alignment and existent problems including subjectivity, reliability index, comprehensive, applicability etcetera in highway alignment evaluation with running speed. On the basis of the “safety first” idea for highway design, the concept of change rate of curvature has been proposed. Curvature change rate is the clear factor impacting on road traffic safety. Road quality evaluation standard is established based on the curvature change rate and its application method in highway alignment design method. The method not only effectively evaluates highway alignment quality, but also may be used as the basis for the selection index of highway geometric design.

Road Traffic Safety

In order to evaluate the level of roads safety, this paper proposes a model of traffic accidents which is derived from theories of synergetics. In this study, a great deal of field survey date is obtained via a set of physiological and psychological detection devices. By analyzing data combined with driving comfort threshold, a model of traffic accidents is founded according to different effects, caused by traffic factors.

Traffic safety dynamic trend pre-warning could effectively strengthenmonitoring strength of traffic management department, reduce the number of trafficaccident and ensure highway transportation orderly and smooth. This article analysestrend pre-warning system of traffic safety from the highway operation managementangle. Based on the above analysis, the trend dynamic pre-warning system composition and the information processing method are advanced. The processingmethods in according to the characteristics of road traffic safety, from trend impactsof traffic safety evaluation indicators use six indicators to reflect all aspects ofsecurity potential crises, such as average speed, traffic flow size, etc.

With the development of the social economy, the level of motorization has been greatly improved, and the traffic safety problem has been paid more and more attention. In recent years, China’s road traffic accident rate showed a trend of decline after rising first, suggests that the Chinese road traffic safety level is on the decline. Road traffic safety evaluation has a positive effect in found risk factors of road traffic safety in time and reduce the traffic accident rate, so the study of traffic safety evaluation method is imperative. And the urban road traffic safety evaluation is frequently viewed as the multi-attribute group decision-making (MAGDM) problem. Depending on the conventional VIKOR method and interval-valued intuitionistic fuzzy sets (IVIFSs), this paper designs a novel IVIF-VIKOR method to assess the urban road traffic safety. In addition, since subjective randomness frequently exists in determining criteria weights, the weights of criteria is [Z1] decided objectively by utilizing CRITIC method. Eventually, an application and some comparative analysis are given. The results show that the designed algorithms are useful for assessing the urban road traffic safety.

Analytic Hierarchy Process (AHP), which needs less information and shorter time on decision-making, is selected for road traffic safety evaluation in this paper. Combined with the instance in Huai Yin district of Jinan city, the structural model that includes road conditions, intersections, straight sections, bends and ramps is proposed. Delphi method was used to construct the judgment matrix and then the MATLAB was used to calculate the corresponding weights of the various index of the entire road system. Combined with self-assessment of each index, then the safety level of the road is figured out.
