Delay to major-street through vehicles at two-way stop-controlled intersections.

This paper describes a methodology for predicting the delay to major-street through vehicles at TWSC intersections. This delay is incurred when major-street left-turn demand exceeds the available storage area and blocks the adjacent through lane. The through-lane blockage problem does not generally occur with significant frequency on streets with divided cross sections that have left-turn bays or lanes; however, it frequently occurs on undivided streets because of their lack of left-turn storage.
