US-75 North Central Expressway Reconstruction: October 1992 and May 1993 Traffic Conditions

K. D. Tyler / R. A. Krammes

This report documents the results of the traffic data collection efforts during the third year (October 1992 and May 1993) of reconstruction on the US-75 North Central Expressway south of the I-635 LBJ Freeway. Traffic conditions and patterns have been monitored during October 1989 and May 1990 (before construction) and during October 1990, May 1991, October 1991, May 1992, October 1992, and May 1993 (during the first three years of the project). The traffic monitoring efforts during October 1992 and May 1993 included traffic data collection and automobile user surveys. The traffic data collection efforts included screen line traffic volume counts, vehicle occupancy and classification counts, and travel time runs. The automobile user surveys are documented in a separate report. The results indicate that the reconstruction activities underway during the October 1992 and May 1993 data collection efforts had little impact on peak period, peak direction traffic conditions and patterns in the corridor.
