DEVELOPMENT OF PROTOTYPE DRIVER MODELS FOR HIGHWAY DESIGN

In an attempt to marshal available knowledge about safety into a more useful form for highway planners and designers, the Federal Highway Administration (FHWA) is developing the Interactive Highway Safety Design Model (IHSDM), a suite of evaluation tools for assessing the safety implications of geometric design decisions. The development of IHSDM is a long-term, multi-year activity. The initial development efforts are restricted to two-lane rural highways -- the largest single class of highways in the U.S., representing approximately two-thirds of all Federal-aid highways. Release of the full model for two-lane rural highways is scheduled for 2002. As currently envisioned, the IHSDM will consist of five modules: Policy Review Module; Accident Analysis Module; Design Consistency Module; Traffic Analysis Module; and Driver/Vehicle Module. The focus of this Research Update is the driver-centered research being performed to support IHSDM. This research includes the development of the Driver Performance Model (one of the Driver/Vehicle Module models) and modifications to the Traffic Analysis Module to improve its representation of driver behavior in traffic.
