Title: Operational effects of geometric design at freeway lane drops
Abstract: Traffic operations at freeway lane drops suffer when geometric design or traffic control devices provide insufficient or misleading information to drivers. This paper discusses the nature of traffic operation problems at freeway lane drop locations and presents eight design principles that should be considered when a lane drop is constructed or updated. These principles include recommendations for planning visibility, location, taper and escape lane characteristics, and traffic control device requirements. A before and after study conducted at a lane drop site in metropolitan Los Angeles illustrates a method for using the design principles to evaluate the effectiveness of a change in traffic control devices at the site.
