• Abstract:
  One of the main tools that the Department of Transportation (DOT) of each state in the United States should have to ; support their work zone activities is a sound model that produces adequate work zone schedules for roadway maintenance ; and construction projects; this should be able to to produce reliable estimates of the impacts on traffic flow characteristics ; due to work zone activity. Existing analytical models used by DOTs have been developed based on traditional ; volume/capacity formulas with deterministic traffic queuing theory. However, the shortcomings of these models often result ; in inaccurate estimates of traffic flow delay, speed and associated costs. The objective of this report is to develop a ; methodology that accomplishes the following: 1) Estimates the traffic flow characteristics in work zones using Floating Car ; Data (FCD) also know as vehicle-probe data. 2) Minimizes the impact of work zones on traffic flow characteristics. 3) ; Minimizes the total work zone impact cost (including maintenance cost, idling cost, vehicle emissions, and user cost) yielded ; by the optimized work zone lengths and the associated schedule. The developed methodology takes advantage of the fact ; that the majority of freeways throughout the United States are now monitored through vehicle probe data that are based on ; the following technologies: 1) The proliferation of a GNSS (Global Navigation Satellite System) in vehicles and cellular ; phones that provide vehicle location and speed data every second. 2) The proliferation of Bluetooth Technology (BT), in ; which vehicle location and speed/travel time are estimated using BT installed at the side of the roadway – while BT is ; currently under more limited coverage, which is expanding rapidly. These FCD technologies provide an added dimension to ; the estimation of traffic flow characteristics in work zones, namely travel time, speed, and associated delay. To test this ; methodology, two case studies were conducted using a real work zone on a segment of Interstate I-287 in New Jersey.
