| 摘要： | Many arterials are hopelessly congested. In many places, engineers have done as much as they can with conventional improvements. Advances like intelligent transportation systems will not provide widespread assistance on arterials for many years. To help treat this impasse, the first author wrote a series for ITE describing seven unconventional design alternatives for arterials. The purposes of this paper are to review five of those alternatives -- the median U-turn, bowtie, superstreet, jughandle, and continuous flow intersection -- and to summarize new information about them. After presenting the advantages and disadvantages of each alternative, the paper suggests when analysts should consider one during feasibility studies and functional designs. |
