| 摘要： | The use of periodic, short-term passing lanes is known in Texas as a 'Super 2' design. The passing lanes may be alternating side-by-side, but they are placed at regular intervals. Passing lanes are often constructed on two-lane roadways to improve overall traffic operations by breaking up traffic platoons and by reducing delays caused by inadequate passing opportunities over substantial lengths of roadway. During the recent design of several 'Super 2' projects, questions arose in three areas: (1) optimum passing lane length and spacing, (2) shoulder width requirements, and (3) optimum signing and driver information (pavement marking etc.) strategies. |
