Available in PDF, EPUB and Kindle. Book excerpt: The ability to collect or estimate accurate speed information is of great importance to a large number of Intelligent Transportation Systems (ITS) applications. Estimating speeds from the widely used single inductive loop sensor has been a difficult, yet important challenge for transportation engineers. Based on empirical evidence observed from the sensor data from two metropolitan regions in Northern Virginia and California, this research effort developed a Kalman filter model to perform speed estimation for congested traffic. Taking advantage of the coexistence of dual loop and single loop stations in typical freeway management systems, a calibration procedure was proposed for seeding and initiating the algorithm. Empirical evaluation showed that the proposed algorithm can produce accurate speed estimates (on the order of 1-3 miles/hour error) under congested traffic conditions.

Download or read book Highway Travel Time Estimation With Data Fusion written by Francesc Soriguera Martí and published by Springer. This book was released on 2015-11-30 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents a simple, innovative approach for the measurement and short-term prediction of highway travel times based on the fusion of inductive loop detector and toll ticket data. The methodology is generic and not technologically captive, allowing it to be easily generalized for other equivalent types of data. The book shows how Bayesian analysis can be used to obtain fused estimates that are more reliable than the original inputs, overcoming some of the drawbacks of travel-time estimations based on unique data sources. The developed methodology adds value and obtains the maximum (in terms of travel time estimation) from the available data, without recurrent and costly requirements for additional data. The application of the algorithms to empirical testing in the AP-7 toll highway in Barcelona proves that it is possible to develop an accurate real-time, travel-time information system on closed-toll highways with the existing surveillance equipment, suggesting that highway operators might provide their customers with such an added value with little additional investment in technology.

Download or read book Examining Information Needs for Efficient Motor Carrier Transportation by Investigating Travel Time Characteristics and Logistics written by William L. Eisele and published by . This book was released on 2001 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents both survey results and field data analysis investigating information needs for motor carrier logistics. Relevant research in the area of estimating travel time characteristics is presented. Survey results of trucking companies and trucking professionals are also included. Although the sample size is low, useful insight obtained from the respondents is discussed. The accurate estimation of travel time data is valuable for a variety of real-time and off-line transportation applications including motor carriers. This report includes methodologies for estimating corridor travel time mean and variance from field data collection at two test sites. The test sites are two limited-access freeway corridors: one instrumented with automatic vehicle identification (AVI) antennas and one instrumented with dual inductance loop detectors at 0.5 mile spacings. The estimates using the intelligent transportation system (ITS) data were compared to simultaneous instrumented test vehicle and commercial vehicle travel time data. A procedure was outlined for using the loess nonparametric statistical technique to obtain corridor travel time mean and variance estimates from each ITS data source, commercial vehicles and instrumented test vehicles. The estimates from each data source were then aggregated to five minutes, and the ITS data source estimates were compared to the commercial vehicle and instrumented test vehicle corridor travel time estimates. A methodology for testing the accuracy of instrumented test vehicle drivers along a corridor was also developed. The research demonstrates that commercial vehicles have statistically different travel time mean and standard deviation than AVI-equipped vehicles, which suggests it may be beneficial to provide traveler information in real-time for commercial vehicles. It was also found that AVI-equipped vehicles were not statistically different than the instrumented test vehicles and that an AVI system with an adequate number of tag reads could replace traditional data collection methods. By comparing inductance loop travel time estimates to the commercial vehicle and test vehicle data sources, the research quantifies how aggregated inductance loop detector travel time estimates do not capture the travel time variance characteristics of individual vehicles.

Download or read book Stochastic Evolutions of Dynamic Traffic Flow written by Xiqun (Michael) Chen and published by Springer. This book was released on 2014-09-18 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reveals the underlying mechanisms of complexity and stochastic evolutions of traffic flows. Using Eulerian and Lagrangian measurements, the authors propose lognormal headway/spacing/velocity distributions and subsequently develop a Markov car-following model to describe drivers’ random choices concerning headways/spacings, putting forward a stochastic fundamental diagram model for wide scattering flow-density points. In the context of highway onramp bottlenecks, the authors present a traffic flow breakdown probability model and spatial-temporal queuing model to improve the stability and reliability of road traffic flows. This book is intended for researchers and graduate students in the fields of transportation engineering and civil engineering.
