A research effort was initiated to develop and test a methodology to estimate the extent to which urban congestion is produced by the routine presence of large numbers of vehicles on a facility (so-called recurring congestion) versus unexpected disruptions or other events (non-recurring congestion), particularly lane blocking incidents. An analysis was performed using a preliminary methodology to estimate the magnitude, extent, and relative causes of congestion on urban freeways in the central Puget Sound region of Washington State. This information is designed to assist transportation agencies in 1) selecting the most appropriate strategies to improve freeway operations, and 2) allocating available resources to achieve those improvements. This paper documents the preliminary methodology and results from this ongoing research project.

This book on road traffic congestion in cities and suburbs describes congestion problems and shows how they can be relieved. The first part (Chapters 1 - 3) shows how congestion reflects transportation technologies and settlement patterns. The second part (Chapters 4 - 13) describes the causes, characteristics, and consequences of congestion. The third part (Chapters 14 - 23) presents various relief strategies - including supply adaptation and demand mitigation - for nonrecurring and recurring congestion. The last part (Chapter 24) gives general guidelines for congestion relief and provides a general outlook for the future. The book will be useful for a wide audience - including students, practitioners and researchers in a variety of professional endeavors: traffic engineers, transportation planners, public transport specialists, city planners, public administrators, and private enterprises that depend on transportation for their activities.

The paper describes a methodology and its application to measure total, recurrent, and non-recurrent (incident related) delay on urban freeways. The methodology uses data from loop detectors and calculates the average and the probability distribution of delays. Application of the methodology to two real-life freeway corridorsone in Los Angeles and the other in the Bay Areaindicates that reliable measurement of congestion should also provide measures of uncertainty in congestion. In the two applications, incident-related delay is found to be between 13 to 30 percent of the total congestion delay during peak periods. The methodology also quantifies the congestion impacts on travel time and travel time variability.

Multimodal transport network customers need to be directed during their travels. A travel support tool can be offered by a Multimodal Information System (MIS), which allows them to input their needs and provides them with the appropriate responses to improve their travel conditions. The goal of this book is to design and develop methodologies in order to realize a MIS tool which can ensure permanent multimodal information availability before and during travel, considering passengers’ mobility. The authors propose methods and tools that help transport network customers to formulate their requests when they connect to their favorite information systems through PC, laptop, cell phone, Portable Digital Assistant (PDA), etc. The MIS must automatically identify the websites concerning the customer’s services. These sites can, in fact, represent transport services, cultural services, tourist services, etc. The system should then be able to collect the necessary travel information from these sites in order to construct and propose the most convenient information according to the user’s requests. Contents 1. Agent-oriented Road Traffic Simulation, René Mandiau, Sylvain Piechowiak, Arnaud Doniec and Stéphane Espié. 2. An Agent-based Information System for Searching and Creating Mobility-aiding Services, Slim Hammadi and Hayfa Zgaya. 3. Inter-vehicle Services and Communication, Sylvain Lecomte, Thierry Delot and Mikael Desertot. 4. Modeling and Control of Traffic Flow, Daniel Jolly, Boumediene Kamel and Amar Benasser. 5. Criteria and Methods for Interactive System Evaluation: Application to a Regulation Post in the Transport Domain, Houcine Ezzedine, Abdelwaheb Trabelsi, Chi Dung Tran and Christophe Kolski.

Transport Planning and Traffic Engineering is a comprehensive textbook on principles and practice. It includes sections on transport policy and planning, traffic surveys and accident investigation, road design for capacity and safety, and traffic management. Clearly written and illustrated, the book is ideal reading for students of transport, transport planning, traffic engineering and road design. Written by senior academics in the field of transport, it is a worthy successor to the widely acclaimed first volume of O'Flaherty's Highways. The content has been expanded and thoroughly updated to reflect the many changes that have taken place in this topical area.

"Reliability of transport, especially the ability to reach a destination within a certain amount of time, is a regular concern of travelers and shippers. The definition of reliability used in this research is how travel time varies over time. The variability can apply to the travel times observed over a road segment during a specific time slice (e.g., 3 to 6 p.m.) over a fairly long period of time, say a year. The variability can also pertain to the travel times of repeated trips made by a person or a truck between a given origin and destination. Agencies are increasingly aware of the issue of reliability, although the transportation industry as a whole as yet lacks a firm understanding of the causes and solutions to failures of reliability. As the agenda for the SHRP 2 research on travel time reliability took shape, it became clear a fundamental study was required to be able to talk about travel time reliability in a meaningful way"--Foreword.
