Evaluation of Operational Effects of Freeway Reconstruction Activities
To better evaluate the operational effects of freeway maintenance/ reconstruction activities, a new methodology has been developed. This methodology takes traffic demand, freeway geometry, and … [Read more...] about Evaluation of Operational Effects of Freeway Reconstruction Activities
Work Zone Analysis Model for the Signalized Arterial
The purpose of this paper is to illustrate new theoretical concepts used to represent traffic flow in work zones. The paper presents the development and applications of a microcomputer program--Work … [Read more...] about Work Zone Analysis Model for the Signalized Arterial
Computer Model for Evaluating and Scheduling Freeway Work-Zone Lane Closures
QUEWZ is a computer model that was developed in 1982 as a tool for planning and scheduling freeway work-zone operations. The model analyzes traffic flow through lane closures in freeway work zones and … [Read more...] about Computer Model for Evaluating and Scheduling Freeway Work-Zone Lane Closures
Guidelines for Positive Barrier Use in Construction Zones
The need for positive barriers in construction zones is now based on individual judgment, and there is an expressed need for objective barrier placement criteria. The number, diversity, and … [Read more...] about Guidelines for Positive Barrier Use in Construction Zones
Developing a Scheduling Tool for Work Zones on Houston Freeways
In Houston the condition of the existing highway network has deteriorated at a far greater rate than can be maintained without affecting traffic severely or endangering the safety of maintenance … [Read more...] about Developing a Scheduling Tool for Work Zones on Houston Freeways
