The objective of this paper is to identify and propose the travelers' information requirements that should be used for designing an integrated passenger information and multimodal journey planning system covering international journeys. A methodological framework was developed for achieving this goal based on the identification and analysis of the travelers' information needs. The data needed to implement the proposed methodology were collected through a travelers' survey covering five European countries and China. The outcome of the proposed methodology indicated that the following types of travelers' information services were rated with the highest weight of relative importance: travelers customized door to door international journey planning, personalized real-time alerts and travel reminders, and dissemination of travel information through the Internet and mobile phones. Similar priorities with only minor deviations were calculated for the potential information services for journey planning and execution in different countries indicating that travelers tend to reach a consensus in the information requirements for international journey planners. sf]Y","PeriodicalId":176645,"journal":{"name":"13th International IEEE Conference on Intelligent Transportation Systems","volume":"19 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131122962","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 problem has direct application to the transportation sector where vehicles leave from a source and need to visit a certain set of locations before returning back to the source. The ITS-TSP algorithm is analyzed to show a worst case running time of O(V3), assuming that all V nodes in a graph must be visited. There is a pre-processing cost of O(V2E!) that must be incurred, though this must only be performed one time for a graph. The algorithm is a heuristic that provides routes that are optimal based on a snapshot of the graph, though as the edge weights change over time, the solution may not be optimal. On a graph of the transportation network in Anchorage, Alaska, we tested the ITS-TSP with live data gathered through vehicle-tracking devices installed in 65 vehicles. With the weight on each edge representing the amount of time to traverse a roadway, the ITS-TSP algorithm always computed the route with minimum cost based on the snapshot of the network.","PeriodicalId":176645,"journal":{"name":"13th International IEEE Conference on Intelligent Transportation Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123722385","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 estimating vehicle fuel consumption rates, the VT-Micro model and a Vehicle Specific Power (VSP)-based model (the PERE model) are considered and compared. The results of the comparison demonstrate that both of the VT-Micro and PERE models provide reliable fuel consumption estimates (R2 of 90% and higher for a 1993 Honda Accord with a 2.4L engine). RSDs capture only an instantaneous snapshot of a vehicle's emissions, and how this single point measurement might be related to the vehicle's overall emission status, to our knowledge, has not yet been mechanistically assessed. For the above sample vehicle, the in-laboratory mass emissions measured over an IM240 driving cycle identified the sample vehicle as a normal emitter in 100%, 97%, and 89% of the second-by-second measurements for HC, CO, and NOX emissions, respectively. The estimated mass emissions based on concentration measurements and the modeled fuel consumption rate yielded normal emitter results in 100%, 97%, and 88% of the measurements. These results suggest a 100%, 100%, and 99% success rate relative to the results from in-laboratory measured emissions. The study clearly demonstrates that the proposed procedure works well in converting concentration measurements to mass emissions and can be applicable in the screening of HEVs and normal emitting vehicles for several vehicle types such as sedans, station wagons, full-size vans, mini vans, pickup trucks, and SUVs.","PeriodicalId":176645,"journal":{"name":"13th International IEEE Conference on Intelligent Transportation Systems","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128320070","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 crucial therefore that the landing lighting performs according to the standards set out by the aviation industry. Researchers at Queen's University Belfast have developed a technique for assessing the performance of landing lighting luminaires whilst in service. However, because of the necessity to keep airport operations functioning as efficiently as possible, it is difficult to test and validate this system on a real landing lighting system. In this paper, we present a technique for testing this system by developing a virtual landing lighting pattern using a computer generated 3D model. This virtual lighting pattern can be used to test and validate the proposed assessment system and subsequently refine the technique before real field trials begin. In this paper we describe the development of the virtual model and compare its performance to an actual lighting pattern, and show that it is possible to accurately simulate lighting patterns. This work has relevance to a range of applications where lighting design and performance are important considerations.","PeriodicalId":176645,"journal":{"name":"13th International IEEE Conference on Intelligent Transportation Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129344458","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}

Bicycle detection is important because bicycles share the road with vehicles and can move at comparable speeds in urban environments. From a computer vision standpoint, bicycle detection is challenging as bicycle's appearance can change dramatically between viewpoints and a person riding on the bicycle is a non-rigid object. In this paper, we present a vision-based framework to detect and track bicycles that takes into account these issues. A mixture model of multiple viewpoints is defined and trained via a Support Vector Machine (SVM) to detect bicycles under a variety of circumstances. Each component of the model uses a part-based representation and known geometric context is used to improve overall detection efficiency. An extended Kalman filter (EKF) is used to estimate the position and velocity of the bicycle in vehicle coordinates. We demonstrate the effectiveness of this approach through a series of experiments run on video data of moving bicycles captured from a vehicle-mounted camera","PeriodicalId":176645,"journal":{"name":"13th International IEEE Conference on Intelligent Transportation Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129628281","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}

A two dimensional Gabor filter and vertical pixel density calculation method was used to find initial lane regions. Second derivative approach of Composite Bezier spline fitting method calculates the exact coordinates of the control points. Score function based on pixel matching was used for determining lanes in curved roads. A template lane matching method with ease of implementation was used for tracking the detected lanes. The proposed system was tested using offline and real time hardware-in-the-loop simulations. The detected and tracked lane information is used in a lane keeping control system, realized in a hardware-in-the-loop setting. The high fidelity, high order, realistic and nonlinear vehicle model in Carmaker HIL is used in hardware-in-the-loop testing. The lane keeping controller works as code in a dSpace microautobox general purpose electronic control unit which obtains the lane data from the vision system running on a laptop PC and Carmaker vehicle data from a dSpace compact simulator for calculating the required steering actions. The system performance was evaluated on different scenarios which contain straight and sharp curved roads, obstacle vehicles and different lane marking types.
