Performance Criteria for Channelizing Devices Used for Two-Lane Two-Way Operations

摘要

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. Lastly, testing procedures are set forth to evaluate whether the specified performance characteristics are met. The evaluation procedures proposed are limited to tests that can be performed in a laboratory or test track environment.
