As a potential intelligent transportation system (ITS) solution, multi-agent intersection management systems have recently received increased attention with the rapid advance in wireless communications and comprehensive vehicular technologies. Most of the proposed multi-agent system approaches take a FIFO (first-in first-out) approach to time-space occupancy scheduling. However, by also optimizing the departure sequence, greater global benefits are possible. In this paper, we propose a modified multi-agent system with optimal scheduling of Vehicle Agent's (VAs') departure times. Compared with the FIFO-based system developed in the authors' previous work, the modified system can provide more system-wide benefits in terms of mobility, reliability and sustainability. Simulation studies have shown improvements in travel times, but more importantly an approximately 58% reduction in travel time variability and 49%-60% reductions in (partial) stops. These leads to potential benefits in fuel consumption and pollutant emissions, primarily by carefully designing VAs' trajectories through the intersection.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122035054","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}

It is a very important part of applications of connected vehicles where there is a constant need for vehicles to exchange information with the communication infrastructure. This could result in the congestion of the network with data. Alternatively information can be disseminated using exclusively adhoc V2V approach. This approach may lead to broadcast storm and jamming of the V2V channel. In this study we evaluate as a proof-of-concept, V2V data broadcast, for an algorithm proposed in an earlier study to build autonomous and dynamic groups. In our recent studies we showed that the hybrid VANETs formed using this algorithm can reduce communication load and are very scalable for sensor data collection. In this study we modify the dynamic grouping algorithm so that the time for which the group is available for data broadcast is improved. This modified algorithm for dynamic grouping of vehicular nodes is implemented in a realistic well-calibrated microscopic traffic simulation test bed of New Jersey Turnpike. We demonstrate the benefit by considering a generic instance of an event-specific data broadcast. This data could be information on accidents, local commercial information, etc. We demonstrate, using initial findings, that the algorithm can be used to contain broadcast storm and reduce bandwidth usage by 65-76% compared to flooding and 45-62% compared to farthest neighbor broadcast protocol. Thus we establish that the dynamic grouping algorithm is an effective solution in many real-world traffic scenarios.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121109673","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}

We design a load-balancing guiding scheme and derive an analytical model in order to reduce the total evacuation time of indoor people. The guiding scheme can provide the fastest path to an exit for people based on the evacuation time estimated by the analytical model. This is the first distributed solution which takes the corridor capacity and length, exit capacity, concurrent move, and people distribution into consideration for estimating evacuation time and planning escape paths. Through the proposed framework, the congestion of certain corridors and exits can be released to significantly reduce the total evacuation time. Analytical and simulation results show that our approach outperforms existing works, which can prevent people from following the local optimal guiding direction with the longer evacuation time in total. We also implement a prototype, called Load-balancing Emergency Guiding System (LEGS), which can compare evacuation time and guiding directions of existing schemes and ours under different people distribution.","PeriodicalId":182453,"journal":{"name":"2012 International Conference on Connected Vehicles and Expo (ICCVE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126523060","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}
