Book Description
Periodic resurfacing, rehabilitation, restoration, and reconstruction work is needed on the aging highway system to maintain a desired level of service for the traveling public. However, temporary work zones on highways disrupt the normal flow of traffic and reduce the level of service. Freeway work zones have become a major source of traffic congestion and travelers' delays which result in reduced freeway capacity, increased driver frustration, increased traffic accidents, increased road user delay cost, and increased fuel consumption and vehicle emissions. In this research, scientific models have been created for estimation of the work zone capacity for the first time. A case-based reasoning (CBR) model has been created for freeway work zone traffic management considering work zone layout, traffic demand, work characteristics, traffic control measures, and mobility impacts. A freeway work zone traffic delay and cost optimization model has been developed in terms of the length of the work zone segment and the starting time of the work zone using average hourly traffic data. An adaptive computational model has been created for estimating the work zone capacity and queue length and delay. A neuro-fuzzy logic model has been developed for estimation of the freeway work zone capacity taking into account 17 different factors impacting the work zone capacity. An object-oriented model has been developed for freeway work zone capacity and queue delay and length estimation. The model has been implemented into an interactive software system, called IntelliZone. IntelliZone's capacity estimation engine is based on pattern recognition and neural network models incorporating a large number of factors impacting the work zone capacity. This research provides the foundation for a new generation of advanced decision support systems for effective management of traffic at work zones. The extensive parametric study of main factors impacting the work zone capacity provides quantitative and objective results of value to work zone engineers and highway agencies when creating traffic management plans for work zones.

Book Description
Volume I illustrates many of the typical worksites describing the most common conditions encountered. The information provided can be used to supplement local, state, and national standards. The topics include, among others: Public information, regulatory control, special traffic provisions, protection of pedestrians, flagging, temporary traffic signals, and nighttime procedures. Volume II is intended primarily for use by job site supervisors. It addresses the most common situations, problems and solutions that supervisors might be faced with. The topics include, among others: Emergency work moving operations, temporary traffic control devices, placing devices, temporary removal of signs, and pedestrian needs.

Book Description
This booklet is intended to be a single information resource for currently available Technology Transfer (T2) products on the subjects of traffic control and safety in highway construction and maintenance zones. This booklet is of particular value to state and local highway engineers who are responsible for planning, managing, implementing and inspecting traffic control devices in work and maintenance zones, as well as to individuals who are in need of, or provide, continuing training on all aspects of work-zone traffic management. For each product listed, the address and telephone number of contact agencies are provided along with a brief description and the terms for acquisition.
