Crash and injury-crash rates increased significantly on segments of an Illinois superhighway undergoing major construction, compared to crash rates of preceding years and to crash rates on segments not undergoing construction. Maintaining separation of traffic on segments under construction resulted in smaller increase in injury-crash rates than crossover diversion of traffic from lanes under construction into previously one-way roads.
与前几年的撞车率以及未施工路段的撞车率相比,伊利诺伊州一条正在进行大规模建设的高速公路路段上的撞车和受伤撞车率显著增加。与将施工车道的交通交叉改道至以前的单向道路相比,在施工路段保持交通分离导致受伤撞车率的增幅较小。
