• Abstract:
  Most people in the US prefer to travel on freeways, but when there is congestion they divert onto local routes to avoid travel delay. This study measures the traffic diversion induced by an increase in congestion on the I-10 freeway in Baton Rouge during congestion, using a Bluetooth Detection System. The main objective of the study was to identify the difference in the level of congestion on the I-10 between the Mississippi River Bridge and the I-10/I-12 split and the level of congestion on local roads that triggers traffic to divert from the freeway to parallel arterials. Other objectives include measuring the time lag between the onset of congestion and diversionary behavior, and observing stability of behavior from incident to incident. The findings of the study indicate that diversionary behavior occurs when the Travel Time Index is 1.5 or above over that on parallel arterials. The time lag observed is 15-30 minutes for incidents occurring on the main section of the I-10 under study (i.e., between Perkins exit and Citiplace), but for incidents occurring on the beginning of the study section (i.e., between Nicholson Drive and Perkins exit), the time lag is between 0 and 15 minutes.
