Research on Highway Roadside Safety

Abstract

Frequent and serious traffic accidents have become a focal issue because they hinder the sustainable development of society. In China, roadside accidents account for 40% of fatalities resulting from traffic accidents. Roadside safety has become an important issue of traffic management departments worldwide, and performing research on roadside safety contributes to improving the level of road safety and reducing the number of traffic accidents and fatalities. By systematically sorting a large number of relevant studies, this paper analyzed the current development trends of roadside safety in terms of three aspects (i.e., the year of publication, the country of publication, and the source of publication) and then summarized the research status, existing gaps, and future development directions of roadside safety in terms of three aspects: the frequency of roadside accidents, the severity of roadside accidents, and the practice of roadside safety design. This paper reviewed the different prediction methods and evaluation models for the frequency and severity of roadside accidents. According to the number of times mentioned in the literature, the first five significant risk factors that cause frequent roadside accidents are small-radius curves, heavy traffic, objects adjacent to the lane (such as poles and trees), narrow lanes, and narrow shoulders, and the first five significant risk factors that cause fatal roadside accidents are driver age ≤25 or ≥65, alcohol, speeding, failure to use seat belts, and heavy trucks. Future research on the frequency and severity of roadside accidents should focus on quantitatively analyzing the probability of roadside accidents and occupant injury risk and developing methods for identifying roadside accident blackspots. For roadside safety design, roadside clear zones and safety slopes should be precisely quantified based on a cost-benefit analysis in future studies.

Driver Fatigue Detection Method Based on Human Pose Information Entropy

“…When drivers are fatigued, the operating speed of the vehicle slows down and the range decreases. Consequently, the frequency and amplitude of changes can reflect the fatigue state of the driver [39]. When the driver is fatigued, not only drowsy facial behaviours (blinking, yawning, and nodding) will occur but also the range of body movements becomes…”

The Effect of Increasing Vehicle Volume on Some Roads in Surabaya Post Pandemic

“…Activities that disrupt the flow of traffic along the highway can be defined as side barriers [23]. Side barriers can be in the form of pedestrian activity, vehicles that stop or park on the shoulder of the road, vehicles coming in and out, and slow-moving vehicles.…”

Identification of hazardous road sites: a comparison of blackspot methodology of Narogong Road Bekasi and Johor Federal Roads

“…Human mistakes can cause traffic accidents among drivers, passengers, and vulnerable road users such as pedestrians, cyclists, and motorcyclists [14]. Driver errors are common, the main ones being excessive speeding [15][16], long-distance driving tiredness, emotional driving [17], Inexperienced driving and consuming alcohol [18] [19].…”

“…The accident rate approach and the equivalent accident frequency method are two of the most extensively utilized accident black spot detection methods. Non-experimental studies were done, for example, before and after the influence of a counting measure on the number of traffic accidents at a crossroads [39]. These approaches are also utilized as fundamental methods in accident black spot detection research, and they are enhanced or combined with other methods to improve identification efficiency and accuracy.…”
