Abstract: To alleviate the passenger and freight congestion problem in the connection section of large logistics parks and the national highway caused by the rapid development of the logistics industry, starting from the traffic flow characteristics of the urban entrance and exit connection section, a calculation model for the length of the weaving area of truck lanes was established, according to the volumn and proportion of turning of trucks and buses at the intersection of the connection section. And the entrance lanes of intersections with different numbers of lanes were channelized. The calculation model for the length of the weaving area of truck lanes and the channelized scheme of entrance lanes were simulated and applied, which verified the feasibility of the weaving area length calculation model and the channelized scheme of intersection.

Key words: traffic and transportation engineering; connection section; transportation organization; truck lane; the national highway

摘要： 为缓解物流业迅速发展导致的大型物流园区与高速公路的国道连接路段客货拥堵问题，从城市出入口连接段的交通流特性出发，根据连接段交叉口货车与客车的转向数量及比例，建立货车专用道交织区长度计算模型，并且对不同车道数的交叉口进口道进行渠化，将专用道交织区长度计算模型和进口道渠化方案进行了仿真，验证了交织区长度计算模型与交叉口渠化方案的可行性。
