Abstract
This thesis explores the effect of intersection skew angle on average queue delay through simulation. The simulation model used is the TEXAS (Traffic Experimental and Analytical Simulation) model. This microscopic simulation model uses a general nonlinear car-following model. It simulates individual intersections and was designed to capture the interaction of traffic operations and intersection geometry.
Simulation models were developed for three stop-controlled, tee-intersections in Lincoln, Nebraska. Field data to develop and calibrate the simulation models were collected. All simulation models were calibrated by adjusting the car following parameters. An experimental design was developed to test the effect of skew angle on average queue delay. Skew angles from 1 degree to 30 degrees were evaluated. The average queue delay reported for each skew angle is based on 30 runs of the simulation model. The results indicate that skew angle does affect average queue delay. The results also suggest that the TEXAS model can capture the effect of skew on average queue delay for small skew angles of 1 degree from the base conditions.
