It augments current public transportation infrastructure by providing users with access to a heterogeneous network of on-demand autonomous vehicles. We use demand and usage data to provide optimized scheduling and dispatching services, which provide passengers access to multiple choices of transportation through different automated shuttle sizes and speeds. The system has been designed to maximize the replicability and scalability for future city-wide deployments. It conforms to the National ITS Architecture to maintain the benefits of possible cooperation with other subsystems of ITS.","PeriodicalId":412356,"journal":{"name":"Proceedings of the 2nd International Workshop on Science of Smart City Operations and Platforms Engineering","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121569337","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}

Koutsoukos","doi":"10.1145/3063386.3063767","DOIUrl":"https://doi.org/10.1145/3063386.3063767","url":null,"abstract":"In a smart city, real-time traffic sensors may be deployed for various applications, such as route planning. Unfortunately, sensors are prone to failures, which result in erroneous traffic data. Erroneous data can adversely affect applications such as route planning, and can cause increased travel time. To minimize the impact of sensor failures, we must detect them promptly and accurately. However, typical detection algorithms may lead to a large number of false positives (i.e., false alarms) and false negatives (i.e., missed detections), which can result in suboptimal route planning. In this paper, we devise an effective detector for identifying faulty traffic sensors using a prediction model based on Gaussian Processes. Further, we present an approach for computing the optimal parameters of the detector which minimize losses due to false-positive and false-negative errors. We also characterize critical sensors, whose failure can have high impact on the route planning application. Finally, we implement our method and evaluate it numerically using a real- world dataset and the route planning platform OpenTripPlanner.","PeriodicalId":412356,"journal":{"name":"Proceedings of the 2nd International Workshop on Science of Smart City Operations and Platforms Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127667914","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}
