A STUDY OF ON-FREEWAY LANE CLOSURE IN THE MERGE AREA OF TWO FREEWAYS

An On-Freeway Lane Closure to adjust the capacity of two roadways to a merge point in order to improve the efficiency of operation of the total I.H. 10-I.H. 610 interchange in Houston is evaluated. Delay studies conducted on I.H. 610 northbound show that closing the outside lane of I.H. 10 facilitates merge operations which result in a savings of approximately 13 vehicle-hours of travel time on a typical day of control. Daily motorist compliance rates were taken, indicating a majority of drivers voluntarily comply with the lane closure signals. Volume and speed studies were conducted and accident data collected which show that the lane closure has no adverse effect on operations in the control area.
