Description:
The effects of altering headways on a high flow freeway are multifarious. Inadequate headways cause flow instability and accidents. Increasing headways can reduce flow and induce jamming, making determining the optimum headway difficult. Using a micro-simulation this article determines the costs of implementing various headway treatment regimes and compares these to the likely benefits resulting from accident reduction. The most beneficial headway regime is then put forward. In order to implement this treatment regime a roadside Intelligent Transport System (ITS) following-distance advisory and enforcement system is suggested. The system takes varying flow and weather conditions into consideration before modifying the headways of drivers.
