Download or read book Traffic Signal Timing Manual written by U.s. Department of Transportation and published by CreateSpace. This book was released on 2015-02-20 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report serves as a comprehensive guide to traffic signal timing and documents the tasks completed in association with its development. The focus of this document is on traffic signal control principles, practices, and procedures. It describes the relationship between traffic signal timing and transportation policy and addresses maintenance and operations of traffic signals. It represents a synthesis of traffic signal timing concepts and their application and focuses on the use of detection, related timing parameters, and resulting effects to users at the intersection. It discusses advanced topics briefly to raise awareness related to their use and application. The purpose of the Signal Timing Manual is to provide direction and guidance to managers, supervisors, and practitioners based on sound practice to proactively and comprehensively improve signal timing. The outcome of properly training staff and proactively operating and maintaining traffic signals is signal timing that reduces congestion and fuel consumption ultimately improving our quality of life and the air we breathe. This manual provides an easy-to-use concise, practical and modular guide on signal timing. The elements of signal timing from policy and funding considerations to timing plan development, assessment, and maintenance are covered in the manual. The manual is the culmination of research into practices across North America and serves as a reference for a range of practitioners, from those involved in the day to day management, operation and maintenance of traffic signals to those that plan, design, operate and maintain these systems.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes the Traffic Adaptive Network Signal Timing Program (TANSTP) of the Urban Traffic Control System. TANSTP is a second generation traffic control package wherein optimal traffic signal timing patterns are generated on-line as a function of current and predicted traffic flow conditions to minimize average network vehicle delay. In addition to the network optimization routine, the package includes a traffic flow predictor, real-time subnetwork determination routine, a subnetwork interfacing routine, a transition optimization routine, and a local intersection optimization routine which adjusts splits and offsets to minimize delay on a cycle by cycle basis.

Available in PDF, EPUB and Kindle. Book excerpt: Traffic signal optimization is recognized as one of the most cost-effective ways to improve urban mobility; however the extent of the benefits realized could significantly depend on how often traffic signal re-optimization occurs. Using a case study from the Northern Virginia Smart Traffic Signal System (NVSTSS), this project sought to determine how often traffic signals need to be re-optimized to provide the greatest benefits. This project developed a new traffic signal timing plan evaluation and optimization program by combining the Integrated SYNCHRO and Platoon Dispersion (ISAPD) model and the OptQuest optimization program. Based on 2001 (base scenario) and 2004 traffic data, five scenarios of re-optimization time intervals (i.e., 2 weeks, 4 weeks, 8 weeks, 16 weeks, and 1 year) were investigated. Study results indicate that (1) determining time intervals for re-optimization in the NVSTSS is feasible; (2) among the various re-optimization time intervals investigated for the Route 50 case study network, the time interval of 1 year was the best for both midday and the PM peak; and (3) the annual net savings from implementing this 1-year re-optimization time interval could be as high as $107,340 and $254,436, respectively, given the assumptions used in the study. The report recommends (1) the annual re-optimization of the Route 50 corridor traffic signal system; (2) the NVSTSS implementation of the combined ISAPS and OptQuest program for measuring "regrets" of not maintaining the optimal timing plan; (3) the adoption by VDOT traffic engineers of the methodology developed in this study, which is based on the combined ISAPD and OptQuest program, for making decisions regarding traffic signal re-optimization; and (4) a future study to investigate the impact of traffic volume growth rates and changes in turning movements as a means of assisting with determinations about traffic signal timing plan re-optimization.

Download or read book Monitoring Real Time Pavement Conditions Using an RFID Wireless Sensing Network written by Brandon D. Malaguti and published by . This book was released on 2015 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: States deal with bellow freezing weather causing roads and the ground below to freeze. When the ground begins to thaw, ice melts, leaving the ground under the roads softer. Large trucks carring heavy loads can cause permanent damage to roads when the roads are in a soft state. For this reason, a seasonal load restriction (SLR) policy is implemented to restrict truck loads during road thaw period. Consequently, SLR imposition results in a lack of profit from trucking and related industry. Currently, no cheap real-time method exists for road monitoring to allow trucks to change loads based on real-time circumstances. The proposed solution to this problem is to implement an affordable system for monitoring road temperatures and moisture using radio frequency identification (RFID) sensors. To successfully place and remove SLRs, the RFID sensors need to detect the current condition of the pavement and relay the condition to a collector, or RFID reader. The current condition of the pavement is measured using external temperature and moisture sensors. An onboard microcontroller unit (MCU) gathers the measured readings and wirelessly transmits the readings to a RFID reader above the surface of the road. Collected data is used by the Sate Department of Transportation (DOT) to properly decide the real time road conditions on a daily or hourly basis, effectively allowing the DOT to place or remove restrictions as necessary.
