Injuries, crashes, and construction on a superhighway

T C Doege, P S Levy

    American Journal of Public Health
    |February 1, 1977
    PubMed
    Summary

    Major highway construction in Illinois led to increased crash and injury rates. Separating traffic during construction reduced injury-crash rate increases compared to diverting traffic onto one-way roads.

    Area of Science:

    • Transportation Engineering
    • Traffic Safety
    • Highway Infrastructure

    Background:

    • Major highway construction projects often impact traffic flow and safety.
    • Understanding crash dynamics during construction is crucial for mitigating risks.

    Purpose of the Study:

    • To analyze the impact of highway construction on crash and injury-crash rates.
    • To compare the safety outcomes of different traffic management strategies during construction.

    Main Methods:

    • Comparative analysis of crash data on Illinois superhighway segments.
    • Evaluation of crash rates during construction periods versus non-construction periods.
    • Assessment of injury-crash rates under traffic separation versus traffic diversion.

    Main Results:

    • Significant increases in crash and injury-crash rates were observed on construction segments.
    • Traffic separation resulted in a smaller increase in injury-crash rates compared to traffic diversion.
    • Construction segments showed higher rates than non-construction segments.

    Conclusions:

    • Highway construction significantly elevates crash and injury risks.
    • Traffic separation is a safer strategy than traffic diversion during highway construction.
    • Implementing effective traffic management is vital for enhancing safety during roadwork.
