This book was released on 2004 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental requirement for effectively monitoring and operating transportation facilities is reliable, accurate data on traffic flow. The current state of the practice is to use networks of point detectors to gather information on traffic flow at fixed points on the roadway network. Traffic monitoring based on wireless location technology (WLT) offers an opportunity to expand the size of the transportation network being monitored at a lower cost than with point detection. In WLT-based monitoring, the locations of individual wireless devices are sampled anonymously. By tracking a series of positions for devices in vehicles, it is theoretically possible to estimate the average travel speed on a road. Although the concept of WLT-based monitoring is attractive, results have been mixed. Field tests have been successful at locating vehicle positions but have not been able to generate traffic information of the quality or reliability required for most applications. This research explored how WLT-based monitoring could be improved by rigorously examining the problem from a system design perspective. The evaluation focused on two measures of effectiveness: (1) the availability of speed estimates and (2) the accuracy of speed estimates. The performance of WLT-based monitoring systems was evaluated through a combination of controlled testing on simple networks and case studies on simulated real-world networks. Significant main effects and interactions were evaluated in a systematic manner using a test bed that combined microscopic traffic simulation and a model of a WLT-based monitoring system. The results revealed several important issues to be considered when designing and implementing a WLT-based monitoring system. The selection of parameters such as the number of vehicles tracked and frequency between readings needs to be tailored to handle localized traffic and geometric conditions. The results showed that well-designed monitoring systems could produce accurate results although there were some situations where performance could be improved. Guidelines for the design and use of WLT-based systems were generated, and future avenues to improve system performance were noted.
Book Synopsis Probe Sampling Strategies for Traffic Monitoring Systems Based on Wireless Location Technology by : Michael D. Fontaine
Download or read book Probe Sampling Strategies for Traffic Monitoring Systems Based on Wireless Location Technology written by Michael D. Fontaine and published by . This book was released on 2007 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transportation agencies have become very interested in traffic monitoring systems based on wireless location technology (WLT) since they offer the potential of collecting travel time data across a wide portion of the road system. Prior tests of WLT-based systems have been unsuccessful, in part because they have treated the road network as a homogeneous entity. This "area-wide" method has inherent limitations, causing congested roadways to be over sampled and uncongested and low volume roads to be under sampled. This project developed a methodology to estimate sampling parameters based on localized traffic conditions in the network, termed a "zonal approach." In zonal WLT systems, the roadway network is disaggregated into smaller areas, termed "zones," based on cellular coverage areas. In this research, two zonal sampling strategies were examined and tested using three simulated networks. When the road network is complex, the zonal priority sampling strategy was found to distribute probes throughout the network and produced a larger number of speed estimates on uncongested and low volume roads. Moreover, the zonal priority strategy improved speed estimation accuracy by 10 percent over the other two sampling strategies. For networks with simple geometry or uniform congested traffic conditions, there were no significant differences among the sampling strategies. The results of this research indicate that the homogeneous approach used by earlier deployments has limitations, and results could be potentially improved by tailoring sampling parameters to a more localized level.

Download or read book Statistical Validation of Speeds and Travel Times Provided by a Data Services Vendor written by and published by . This book was released on 2010 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The provision of real-time traffic and travel time information is becoming increasingly important in urban areas as well as in freight-significant intercity corridors. However, the high cost to install and maintain roadway-based traffic sensors has prevented widespread availability of real-time traffic information in these areas. A market for real-time traffic information is emerging in the United States and several private companies are gathering and distributing traffic information independently of public sector transportation agencies. In this study floating car, probe data, and newly developed Bluetooth device matching methods are developed and used to collect travel times and speeds for 103 centerline miles located in Dayton, Ohio. This reference data are then statistically evaluated with a data service vendor's reported travel times and speeds for 36 travel time segments.

Book Synopsis V2V/V2I Communications for Improved Road Safety and Efficiency by : Ronald K Jurgen
Download or read book V2V/V2I Communications for Improved Road Safety and Efficiency written by Ronald K Jurgen and published by SAE International. This book was released on 2012-08-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of automobile accidents occur worldwide each year. Some of the most serious are rear-end crashes, side crashes within intersections, and crashes that occur when cars change lanes or drift into a lane. The holy grail of traffic safety is to avoid automobile accidents altogether. To that end, major automakers, governments, and universities are working on systems that allow vehicles to communicate with one another as well as the surrounding infrastructure (V2V/V2I for short). These systems show promise for such functions as intersection assist, left-turn assist, do-not-pass warning, advance warning of a vehicle braking ahead, forward-collision warning, and blind-spot/lane-change warning. This compendium explores the challenges in developing these systems and provides the latest developments in V2V/V2I technology. It begins with a series of overview news stories and articles from SAE’s magazines on the progress in this technology. This is followed by a series of technical papers on V2V/V2I dealing with the many technical aspects of design of these systems as well as discussions of such key issues as the need for extreme reliability assurances and traffic congestion overloads on the systems. Some of most interesting discussions in the book include: • Overview of a large-scale test in Germany to address reliability. • Effectiveness of different antennas and receivers that are used in various intersections settings, such as intersections where there are tall buildings or no buildings, and where high transmission power lines are located that can cause signal interference. • Various ways to communicate between vehicles and how messages are relayed to drivers. • Dedicated short range communication protocol for vehicle safety applications, which shows promise for combining and processing large amounts of information. Editor Ronald K. Jurgen prepared this book to be of use to engineers at automakers and electronic component suppliers; software engineers; computer systems analysts and architects; academics and researchers within the electronics, computing, and automotive industries; legislators, managers and other decision-makers in the government highway sector; traffic safety professionals; and insurance and legal practitioners. Mr. Jurgen served on the editorial staff of IEEE Spectrum for 30 years and is the editor of several electronics-related handbooks and several other electronics-related compendiums published by SAE International.
