“…For example, Park et al used this method to analyze safety effects of wider edge lines and assess traffic safety [20]. Khan et al used Bayesian before-after analysis to study the effectiveness of shoulder rumble strips in reducing run-off-the-road crashes on two-lane rural highways and analyzed their safety benefits for decreasing traffic accidents [21]. de Oña et al combined Bayesian statistics with latent class cluster analysis to identify the primary factors impacting road traffic, reveal underlying traffic safety problems and analyze the safety of rural roads [22].…”

Suburban roads are an important part of China’s road network and essential infrastructure for rural development. Poorly designed road curves and scarcity of traffic signs have caused an excessively high traffic accident rate in plain topographical areas. In this study, an approach to evaluate and improve rural road traffic safety is introduced. Based on fuzzy and cask theory and weighted analysis, a cask evaluation model is built. It provides a quantitative instant method for analyzing road safety in the absence of traffic accident information or rigorous road space data, by identifying dangerous sections and key impact factors, and ultimately help to put forward traffic safety improvements. Based on the application to a specific section of Xiaodang Central Road in the Fengxian District of Shanghai, the result shows that the pavement conditions of cement-hardened dual-lane rural roads was good, but traffic safety was poor. Missing traffic signs, unreasonable road alignment, and poor roadside conditions were the main problems. Finally, improvements of the short-stave subsystem were proposed: the location of guide signs and roadside conditions should be improved, and the number and efficacy of the rural road traffic signs need to be increased, and markings should be and receive regular maintenance.

“…They found that combining visual narrowing of the lanes and applying rippled surfaces on road edges reduced driving speed compared to a control location with edge and centreline marking due to increased mental workload and discomfort while driving at higher speed. Overall, Khan, Abdel-Rahim, and Williams (2015) concluded that rumble strips lead to fewer crashes in car drivers. However, Wu, Donnel, and Aguero-Valverde (2014) did not find effects on injury severity.…”

Cycling on the edge: the effects of edge lines, slanted kerbstones, shoulder, and edge strips on cycling behaviour of cyclists older than 50 years

To prevent single-bicycle crashes, this study is the first to evaluate effects of slanted kerbstones, edge lines, shoulder strips, and edge strips on cycling behaviour of cyclists !50 years. In Experiment 1, 32 participants cycled on a control path and paths with edge lines, slanted kerbstones, and three types of 0.5 m wide shoulder strips (with grey artificial grass, green artificial grass, or concrete street-print). In Experiment 2, 30 participants cycled a different route including a control path and paths with edge lines or 0.3 m white edge strips. Cyclists rode closer to the main cycle path's edge in the shoulder strips conditions, although the presence of these strips resulted in a larger total distance to the verge compared to the control condition. Furthermore, cyclists cycled further from the verge in the edge strip condition than the control condition. Safety implications of the shoulder and edge strips are considered to be positive.

“…Road characteristics also were identical throughout the expressway, so segmentation of on-road data cannot be done using geographical points on the road. The Bangkok driving cycle uses travel speed to partition road segments [17], and many traffic-related analysis road segments with similar geometric features, especially degree of curvature, have been identified using speed ranges [23]. Similarly, travel speed was used to partition the data set for the SEW.…”

This paper critically evaluates traffic related performance of the Southern Expressway (SEW) in Sri Lanka using basic traffic engineering parameters such as average speeds, acceleration-deceleration changes, root mean square acceleration, and positive kinetic energy. An on-road speed/time data sample was collected, and a driving cycle was developed to compare to well-established driving cycles worldwide. Ten traffic-related parameters were identified in order to evaluate the SEW using the collected data. Data was collected in proportion to the number of actual trips made by users on an average day using the on-board method; the segment-based method was adopted for cycle construction. Previously identified traffic-related parameters were used to evaluate and select representative cycle for the SEW from candidate cycles. The selected driving cycle was 1213 s in length. Average speed, average acceleration, and average deceleration were 80.6 km/h, 0.45, and 0.25 m/s 2 , respectively. Results showed that both average and running speeds of the SEW were significantly below compared to its posted speed limit, thereby increasing the travel time. Comparatively smooth driving behavior will improve the SEW's fuel and emission performances. This study created a platform with which future studies can evaluate performances of all operational and future expressways.
