Title:

An Investigation of the Traffic Safety Performance of PPP Transportation Projects in the United States

Abstract:

Public-private partnerships (PPP) have been initiated by several governments in order to gain time and cost efficiencies in the delivery of transportation infrastructure assets and services. With operation and maintenance becoming parts of the contracted services under the performance-based PPP agreements, it is expected that the private partners will exert the efforts to keep the facilities at the best physical conditions and level of service. Little, however, have been published citing whether PPP can have any impact on the roadway safety. The research in this area shows that PPP agreements in the United States have provided no special attention to safety incentives to encourage the private partners to improve safety. PPP industry practitioners emphasized on that PPP through its quality maintenance, fast response to incidence, and management of traffic to keep congestion at minimum will all provide for better and safer roads. This research provides an initial investigation on whether PPPs would have any impact on roadway safety. While the number of PPP projects that are operational are not large, the research carried out descriptive and statistical analysis on nearly most of the projects that are operational. Accidents, fatalities, and injuries on PPP projects, their localities, and states were analyzed. The findings show that safety rates on PPPs do have better safety figures than those of traditionally delivered highways, but not on all dimensions. This should be considered in line with the fact that none of the PPP projects in the United States provided for incentives on roadway safety improvements.
