Queue and Users' Cost in Highway Work Zones

Illinois Department of Transportation (IDOT) BDE manual requires that traffic control plans for freeway reconstruction projects include a queuing analysis. The manual does not provide procedures for calculating speed and capacity of work zone. Capacity plays a critical role in queue length and road user cost calculations. This study will develop methods for estimating speed, capacity, delay, queuing, and user's costs for interstate highway work zones where queuing and congestion occurs. The methods will help IDOT to meet the requirements of Work Zone Safety and Mobility Policy that went into effect in fall 2007.
