Abstract:Highway work zones, particularly those on urban high-speed roads, require special attention and adequate traffic management to reduce the adverse impact of altered geometry and traffic that differ from typical conditions. Super 70 was an urban reconstruction project (March-November 2007) along I-70 in the central part of Indianapolis. In that project, INDOT applied several innovative and traditional solutions such as movable barriers, prohibiting heavy vehicles, closing selected ramps, reducing the speed limit, and aggressive enforcement of traffic restrictions. Unlike many past work zones, the frequency of crashes in the Super 70 work zone segment was reported to be less during its construction period of nine months. The question addressed by the presented study was whether this reduction was merely a result of reduction in traffic volume passing the work zone, or did the novel safety countermeasures that were applied also play a role in enhancing the work zone’s safety? Another important safety aspect was the potential migration of the risk of crashes away from the work zone to other roads that received the diverted traffic.
