An optimization tool for intesction design

Intersection design is a balancing act of various elements and constraints to produce a solution that will address mobility, safety, environment, and financial aspects of the project. To achieve this balance, alternative strategies and options must be identified, developed and evaluated in a systematic manner. Shrinking state transportation budgets require the development of designs and solutions that are more efficient and practical in addressing project needs. An optimization tool has been developed that is capable of evaluating several alternative traffic control and intersection designs for a given location. This tool incorporates safety, capacity, cost and non-motorized transportation criteria to determine an optimum design.
