Highly dynamic traffic information is one of the most important features in vehicular networks, which makes data services very challenging, as the data quality drops over time dramatically and timely data update is expected to maintain the service quality. In this paper, we consider the system architecture, in which vehicles coming from different directions are able to sense and carry upto-date location-based information along their trajectories and upload fresh information to the roadside unit (RSU) when passing through. Meanwhile, vehicles may request information from the RSU for other routes. To enable efficient data services in such a scenario, firstly, we characterize the freshness of temporal data. Then, based on the general form of data quality function, we propose a heuristic algorithm called priority-based scheduling (PBS), which synthesizes the data quality, the broadcast effect and the real-time service requirement in making scheduling decisions. A comprehensive performance evaluation demonstrates the superiorty of PBS under a variety of scenarios.","PeriodicalId":124818,"journal":{"name":"2015 IEEE 18th International Conference on Intelligent Transportation Systems","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129285021","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}

In those kind of carsharing systems the rental vehicle does not need to be returned to a particular station but can be parked in any part of the operating area. There have been hardly any empirical findings on the use and effects of free-floating carsharing so far. Thus, this work presents results of user surveys (onCar questionnaire, online survey and discussions with focus groups) with customers of the free-floating carsharing operator DriveNow. Next to the analysis of the user the usage of such a carsharing system is evaluated by booking data of trips in Berlin and Munich from 2013. The Getis-Ord-Gi*-test is used for analyzing the spatial distribution of booking starts. The operator launched 60 electric vehicles in the fleet that makes an additional analysis for this special kind of free-floating carsharing possible. All approaches want to draw an informative picture of a typical free-floating carsharing user on the one side and about how this new mobility service is used in urban areas on the other side. By the discussions in the focus groups one obtains furthermore an impression about the acceptance of electric vehicles by the customers. One clear conclusion is that free-floating carsharing is mostly used by young well-educated people with an over-average income. Two main purposes of the trips are the way home and leisure time activities. The system is well-working in city or district centers while there are considerably less bookings in peripheral areas. This is also correct for electric free-floating carsharing that is principally accepted by the customers.","PeriodicalId":124818,"journal":{"name":"2015 IEEE 18th International Conference on Intelligent Transportation Systems","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131511254","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}

Spatial data mining and clustering allows to partition heterogeneous networks into homogeneous regions and chase spatiotemporal growth of congestion, which is crucial for real-time hierarchical traffic control schemes. In this paper, we develop and solve a binary quadratic optimization model for partitioning heterogeneous networks taking into account contiguity and size constraints for clusters. The proposed approach utilizes set of distinct and robust homogeneous components in the network called 'snakes'. In the context of this paper, 'snake' refers to a sequence of links created by adding new adjacent links iteratively based on their similarity to join previously added links. Firstly, snakes corresponding to all different initial points grow in a way that they have the highest possible homogeneity. Based on robust behavior observed in sub-regions with different level of congestion, we reduce the search space by selecting a sub-set of distinct snakes which cover different parts of the network. Secondly, a quadratic binary optimization framework is designed to find major skeleton of clusters from obtained distinct snakes by minimizing a heterogeneity index. Finally, a fine-tuning step is utilized to associate unassigned links, remaining from the first step, with proper clusters. The proposed clustering framework can be applied in heterogeneous large-scale real networks with fast computation to obtain low variance clusters.","PeriodicalId":124818,"journal":{"name":"2015 IEEE 18th International Conference on Intelligent Transportation Systems","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127002873","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}
