Highway Planning and Operations for the Dallas District: Freeway System Plan Methodology

The System Planning Methodology was developed jointly by the Texas Department of Transportation (TxDOT), North Central Texas Council of Governments (NCTCOG), Dallas Area Rapid Transit (DART), and Texas Transportation Institute (TTI) as a transportation corridor and system analysis tool that would bridge the gap between regional planning and detailed corridor design. It allows for the examination of peak hour person movement for different facility types within a corridor and estimates associated public costs (e.g., right-of-way, construction, operation, congestion, and environmental costs). The objective of the methodology is to find the lowest total public cost alternative. This project extends the methodology to include costs associated with traffic incidents (nonrecurrent congestion) and tests the results on five corridors in the Dallas area to determine if it alters the recommended alternative previously identified for each corridor. It also adds toll lanes and high occupancy/toll lanes (HOT) as alternatives that can be evaluated against other combinations of general purpose lanes, high occupancy vehicle (HOV) lanes, and express lanes.
