Frequently encountered scenarios include evaluating the severity of vehicle collisions to dispatch appropriate law enforcement and ambulatory services, or issuing time-sensitive AMBER alerts to assist in the effort to find missing or kidnapped children. Due to the unacceptably high cost of ITS equipment failures, preventative maintenance and dense operational testing are high priorities. In this paper we present a low-cost distributed instrumentation system (DIS) for continuous monitoring of critical ITS components. Over the last three years, we have developed and deployed the DIS in the Oklahoma Department of Transportation (ODOT) private fiberoptic network that spans several major metropolitan areas in and around Oklahoma City, Tulsa and Lawton. The Oklahoma DIS is responsible for monitoring the health of the entire ODOT ITS communications network as well as the integrity of each camera video signal and the operational status of each DMS. All of the information acquired by the DIS is integrated into an operational summary that is available on a private website for the design and execution of ITS equipment maintenance plans. In Oklahoma, information acquired by the DIS has been successfully integrated into a wide range of operation and maintenance (O&M) planning, which has led to a significant improvement in terms of overall ITS quality of service (QoS) and a quantifiable reduction in wasted costs associated with the premature discarding of energy storage devices.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132964884","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}

For future ADAS, relevant to traffic safety, high precision digital maps including detailed information about the course of individual lanes are needed. We introduce a new method for the generation of highly accurate digital maps including lane specific information based on a wide range of raw data sources. We show that the use of arc splines as a representation model of individual lanes is advantageous for both computational efficiency and accuracy. Therefore, this method is useful for a wide variety of applications using digital maps to enrich driving comfort and traffic safety.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122623952","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 crux of the protocol is a modified directed diffusion policy, which is used to generate multiple paths within an ellipse, these paths may intersect each other at intermediate nodes which use network coding to maximize the throughput. A comparison with traditional multi-path routing algorithms, which deliver node-disjoint and non coding-aware solutions, reveals that GeoCode is able to achieve the same throughput using only 1/3 of the transmission area, thus mitigating the interference and reducing the overall energy consumption.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123982362","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}

This paper investigates driver's trajectory planning behavior based on vehicle test data of double lane change (DLC) maneuvers. Several hypotheses on driver's trajectory planning for the DLC maneuver are proposed and evaluated. Closed-loop simulations with look-ahead steering controllers consistently demonstrate that by simply fitting a trajectory to the actual trajectory and optimizing the control parameters of the look-ahead controller fail to capture drivers' steering behaviors. Based on the vehicle test data, the paper further hypothesizes that drivers use specific target points as references for control. Both open-loop analysis and closed-loop simulations indicate that, instead of planning and following a desired trajectory, drivers use moving targets along the lane to be changed to as control references during the DLC maneuver.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127731081","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 main issue is to evaluate when such advantages exist. In this paper we analyze the Lisbon bus network on face of the evaluation of when this integration is interesting. We present its availability and range (in terms of distance and time) in order to highlight the areas where the commuter may benefit from a soft mobility option. The main objective is to use this information to determine the best spots for providing soft mobility means of transportation, as well as to advise a commuter about the best travelling option. We argue that this approach is useful for similar bus networks in other cities.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128939944","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 eco-driving assist system consists of a visual indicator illustrating the eco-driving. In the proposed adaptive system, the resolution of the indicator and the threshold of eco-driving are changed to adapt to the driver's skill. The proposed eco-driving system was installed in a driving simulator. Changes in driving behavior and the corresponding eco-driving scores, measured over five days, were investigated. As a comparison, experiments were conducted on a system without any level changes (a non-adaptive system) and on one without any assist system. In the results, eco-driving scores were higher with the assist systems than without them. The score with the adaptive system increased through the trial days, while no clear tendency was found with the non-adaptive system.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"5 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129169548","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}

Planners and managers may choose from a range of available simulation tools that differ in the accuracy (i.e. fidelity) of their representation of real-world demand and supply phenomena. These tools can generally be classified as microscopic, mesoscopic or macroscopic, representing a decreasing order in level of detail and realism. In this paper, we showcase TransModeler, a simulation tool that can seamlessly handle all three fidelity levels simultaneously, on the same network. This hybrid simulation approach (released first in TransModeler in 2006 and subsequently used extensively by consultants) allows agencies to simulate very large urban networks while choosing the links, segments or corridors that require a detailed, microscopic focus. We present some methodological concepts behind Trans-Modeler, its dynamic equilibrium capabilities, and illustrative case studies on real-world networks.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128829699","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}

While the first variant performs this image prediction based on explicit landmark information of a digital map, the second variant predicts camera images directly based on aerial images. In doing so, no conversion step from aerial images to feature maps is necessary. Finally, the paper presents results for both approaches based on extensive test drive data with highly accurate reference data.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116861438","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}

Particularly critical are the errors due to the so called non-line-of-sight (NLOS) satellites. In a NLOS situation, the only way the satellite signal reaches the receiver is by means of reflections on plane surfaces, typically buildings, causing overestimates of the pseudoranges between the satellites and the antenna. Receivers not always distinguish between the direct signals and the multipath effects, leading to un-modelled GPS errors. This paper presents a solution to the problem of multipath effects in urban areas, by means of simple elevation models of the environment. The description of the buildings is stored in a elevation-enhanced digital map (EEMap) that can be consulted to decide whether a certain satellite may be in direct view or not. The validity of the concept is proven by means of real experiments in built-up areas of Spain.","PeriodicalId":186596,"journal":{"name":"2011 14th International IEEE Conference on Intelligent Transportation Systems (ITSC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115411244","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}
