Before-and-After Traffic Study for Indirect Left Turns on Grant Rd., Tucson

The objective of this project is to evaluate the performance and operational impacts/benefits before, during, and after the indirect left turns (ILTs) are constructed on Grant Rd. In addition to the Grant Rd/Oracle Rd intersection, two ILT intersections will be constructed between Stone Ave and Park Ave on E. Grant Rd. The analysis will focus on the mobility aspect of the existing and new ILT intersections on Grand Rd.
