The I-45 North Freeway in Houston is currently undergoing a major reconstruction process. As Phase 2 of the reconstruction project is initiated, it has become necessary to implement several traffic-constricting activities, which are likely to affect mobility in an adverse manner. This paper presents an assessment of how the public is perceiving the traffic conditions during the reconstruction activities. Data on commuter travel times, travel distances, travel modes, and primary travel routes before and during reconstruction periods are presented. A similar effort was undertaken in Pittsburgh, Pennsylvania, during the reconstruction of the I-376 Parkway East. When possible, comparisons between the Houston and Pittsburgh data are presented. In general, it appears that most North Freeway commuters perceive little or no change in traffic conditions during this phase of the reconstruction. On the average, they depart 1.2 min earlier for work or school, travel distances measuring only 0.02 mi longer, and report a 1.2-min increase in travel time. Parkway East commuters, on the other hand, departed 29 min earlier for work or school, traveled distances 3.31 mi longer, and reported that it took 4 min longer to reach their destinations during reconstruction. Mode shifts in both Houston and Pittsburgh were very small, suggesting that the majority of commuters in both cities were not sufficiently inconvenienced by the reconstruction activities to look for another means of travel to work or school.
