Mid-America Transportation Center: Final Reports and Technical Briefs
On January 2, 2008, the Missouri Department of Transportation (MoDOT) closed significant portions of Missouri Interstate 64 (I-64) in St. Louis County for reconstruction. During the planning stages of this project, the proposal to close all lanes of I-64 was met with public concern regarding the possible safety risks associated with diverting I-64 traffic to adjacent roadways. A specific concern was the possibility of increased crash rates on roads designated to receive I-64 traffic flow. The following research was conducted to assess the actual outcomes related to these concerns. Crash analyses and crash rate analysis of 2008 and 2009 crash …

This report presents the results of work zone field data analyzed on interstate highways in Missouri to determine the mean breakdown and queue-discharge flow rates as measures of capacity. Several days of traffic data collected at a work zone near Pacific, Missouri with a speed limit of 50 mph were analyzed in both the eastbound and westbound directions. As a result, a total of eleven breakdown events were identified using average speed profiles. The traffic flows prior to and after the onset of congestion were studied. Breakdown flow rates ranged between 1194 to 1404 vphpl, with an average of 1295 …
