A case study on safety measures at median openings on four-lane trunk roads in China
- 2016
-
Konferensbidrag (refereegranskat)abstract
- This paper describes the safety improvements that were made to an 11km long section of Class-I highway in Hexian county in the province of Anhui (chainage K45 to chainage K56) and summarizes the results of tests used to evaluate the likely changes in risk. Class-I highways mainly function as arterial highways with high design speeds (e.g. 80km/h, 100km/h) but have at-grade intersections and access points (that is, they are not accessed controlled). They typically have two lanes in each direction with a median. Following the occurrence of two deaths and four injuries on the road section during a four month period, conditions on the road were examined, including conducting a ChinaRAP assessment, and improvements were rapidly made. The improvements included speed management, adjustment of median openings, installation of protected turn lanes and delineation. In the 12 months after the improvements were made, no fatal or serious crashes occurred. Evaluations also show that there have been reductions in speed, improvements in the ChinaRAP risk scores and good acceptance of the changes by the local community.

Situations and challenges of road safety in China

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Although the road safety in China has made great achievement, the current situation is still not optimistic. The new situations and challenges of road safety in China are analyzed. There are still many factors affecting road traffic safety, and the foundation of road safety is still weak. Currently, the accidents are likely to relapse, the accident rate and lethality rate are very high, the road safety in rural areas is not optimistic, the accidents caused by commercial vehicles frequently happened, and the devastating accidents with group deaths and injuries are still very frequent. The challenges include: the hidden dangers are prominent, the safety awareness of citizens is very poor, and the management, enforcement of road safety and emergency rescue skills are low.With a series of policies and measures gradually taking effect, road traffic accidents in China went down quickly. China has successfully achieved the objectives of curbing high incidence and gradually reducing accidents, gradually improving road safety year on year. Although the road traffic safety has been keeping a relatively stable level, there are still many factors affecting road traffic safety, and the foundation of road safety is still weak.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Highway Surveillance and Control System (HSCS) is the critical system to improving the traffic safety and efficiency of highway. In this paper, the fault diagnosis model of HSCS based on Petri Net Model is provided in line with the composition, fault types and features of HSCS, and subsequently the fault diagnostic algorithm is given. In the end of this paper, the fault diagnosis of Microwave Vehicle Detector (MVD) in HSCS is presented to verifying the proposed fault diagnosis model and algorithm.
