In Cambodia, motorcycle use has spread rapidly in recent years, and serious accidents involving motorcycles have increased. Motorcycle accidents involving young people are particularly common, and there are various issues concerning traffic safety. To understand the situation in Phnom Penh, Cambodia, we conducted a questionnaire survey on driving attitude and behavior of motorcycle users targeted at high school and college students and a video observation survey of motorcycle driving conditions. Based on the survey analysis results, we held a traffic safety workshop (WS) comprising practical skills and classroom learning centered on hazard anticipation. In this study, we conducted a statistical comparative analysis of driving behavior frequency on non-intersection intervals of arterial roads before and after the WS, based on observational results from video cameras mounted on motorcycles. The results showed that the WS effects were associated with a reduction in average travel speeds and changes in driving behavior, such as frequency of lane changing. Different responses to the WS were observed according to attributes, and thus, the relationship between the content of this kind of traffic safety WS and behavioral changes needs to be clarified and a more advanced traffic safety WS program developed. 相似文献

Traffic prediction is critical for the success of intelligent transportation systems (ITS). However, most spatio-temporal models suffer from high mathematical complexity and low tune-up flexibility. This article presents a novel spatio-temporal random effects (STRE) model that has a reduced computational complexity due to mathematical dimension reduction, with additional tune-up flexibility provided by a basis function capable of taking traffic patterns into account. Bellevue, WA, was selected as the model test site due to its widespread deployment of loop detectors. Data collected during the 2 weeks of July 2007 from 105 detectors in the downtown area were used in the modeling process and traffic volumes predicted for 14 detectors for the entire month of July 2008. The results show that the STRE model not only effectively predicts traffic volume but also outperforms three well-established volume prediction models, the enhanced versions of autoregressive moving average (ARMA) and spatiotemporal ARMA, and artificial neural network. Even without further model tuning, all the experimental links produced mean absolute percentage errors between 8% and 16% except for three atypical locations. Based on lessons learned, recommendations are provided for future applications and tune-up of the proposed STRE model. 相似文献

In this study, we explored the potential of using electronic toll collection (ETC)-derived data that are a part of intelligent transport systems (ITS). Dynamic origin–destination (OD) traffic volumes were estimated using ETC data on the Hanshin Expressway. A dynamic OD estimation model that was suggested in a previous study was used, and abundant ETC data were input to improve the estimation accuracy. The results of OD estimation were analyzed to understand traffic demand and its variation. External factors were clarified that have an influence on variances in the OD flows, and statistical analysis methods for the variations were proposed depending on the factors. Moreover, the improvements in traffic simulation accuracy and performance as a result of using ETC data as input variables in the simulation models were discussed. According to the results of this study, ETC data have potential to assist in understaningd traffic demand and its variation, and the results can be applied to network management. 相似文献
