Abstract:
Two-lane, two-way operation (TLTWO) is the situation created when one directional roadway of a divided, four-lane highway is closed for construction or maintenance operations and the traffic which normally uses that roadway is crossed over the median and shares the other roadway with opposing traffic. The remaining open roadway is operated with one lane in each direction with passing prohibited. Functional requirements are developed for two TLTWO device concepts: (1) an improved flexible, durable, self-restoring device of modest size having a post or paddle shape, and (2) a continuous, raised median with intermittent, high-visibility devices mounted thereon. Performance criteria are then determined which will ensure that a channelizing device meets these requirements.
