Most studies focus on developing algorithms to find the shortest path while some studies explore the average length of the shortest paths. However, the quartiles and variance of the shortest paths have not been studied so far. The quartiles and variance of the shortest paths are important because they can give information about the travel/delivery time reliability and the best and worst travel/delivery time scenario, when the tour can be regarded as TSP. This study performs experiments to find the shortest path connecting n customers, which are generated randomly in a specified service area, using genetic algorithm. The service areas considered include equilateral triangle, rectangle with ratio of length and width ranging from 1 to 8, regular hexagon, and circle. The number of customers considered range from 10 to 100 with an interval of 10. In each experiment, the customers are generated randomly for 500 times. The first, second and third quartiles as well as the variance of the 500 shortest paths have been recorded. Subsequently, regression models have been developed to estimate quartiles and variance using number of customers and parameters of service area. R squares of the developed models are all above 0.96, indicating very good fit. The constructed models can be used to estimate the travel time variance and reliability.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"931 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133383768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the actual measurement and analysis, it is found that the separate dual-left turn traffic flow has obvious interference at the exit position of the intersection, the traffic efficiency is significantly lower than the entrance position. According to the analysis of vehicle mutual interference based on separate dual-left turn traffic flow at exit position and quantization model of force and relative position, this paper gives the range of safety distance between the left-turning vehicles driven in inner and outer lanes. It analyzed the turning angles of vehicles driven in both inner and outer lanes by the exit position. Based on all the researches this paper brings out a guide line setting method for vehicle flow release in the case of separate dual-left turn lane setting is proposed. This research fulfills the blank of the existed traffic guide line setting specification GB5768.2, which makes a significant theoretical support for the signalized intersection traffic guide line setting work.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132109599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ridesourcing softwares like Uber and Didi have been widely accepted and used. As a model of travel, the ridesourcing has many features, like convenience and flexibility, and the origin and destination of every trip are completely determined by passengers, the running track of vehicles can directly reflect the travel behavior of urban residents. So this paper will study the passengers’ travel behaviour by data mining based on the Didi order data, try to reveal the travel characteristics of urban residents from a macro perspective. This paper focuses on these issues: to analyze the order data from ridesourcing company Didi; to explore the temporal characteristics of passengers’ travel from different angles like the temporal distribution of travel, the distribution of peak hour, time consumption; to analyze the spatial characteristics from the different aspects including the distribution of travel distance, travel hot spots; to propose an optimization model of the taxi stand location by analyzing travel characteristics, which can improve user’s experience of residents by setting up reasonable site layout. Finally we found that the ridesourcing track data can well reveal travel characteristics of urban residents, which could be helpful for the urban planning and road network optimization.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115893927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
