Monitoring of Texas Vehicle Lane Restrictions

This research evaluated truck lane restrictions in Texas and further developed guidelines for future implementations on the freeway system. The truck lane restrictions on the I-10 East Freeway in Houston have had a long-term (since September 2000) impact in reducing crashes during peak traffic periods. Although vehicle restrictions may not be necessary on all freeways, the restrictions should be implemented 1) if the guidelines are met, 2) if it is the opinion of the local traffic engineers that crashes may be reduced, 3) if commitment of local law enforcement has been assured, and 4) if there are no adverse impacts to truck movement and commerce in terms of goods movement.
