The DDI accommodates high volumes of left turns at signalized interchanges by eliminating the need for left-turn phase signals.

Stopping distances are increased with higher speeds. 271 0 obj <> endobj There are three parts to a controlled access exit ramp: merging lane, deceleration lane and exit ramp. The type of interchange, the shape and pattern of the interchange ramps for the various turning movements, and their design are governed by several factors such as the importance of the intersecting highways, the number of intersecting legs, the design volumes of through and turning traffic movements including their composition, the design speeds, available right of way and topography. 9) Driving on expressways is not any different then driving on regular roads. Several key design elements are utilized to help prevent driver error: In a Federal Highway Administration DDI simulation study, not one of the more than 1,000 participants drove the wrong direction at the crossovers or incorrectly turned into oncoming traffic lanes.
