| 摘 要： | 隧道和互通式立交作为高速公路的重要构筑物，其科学合理的间距直接影响高速公路路线走向和运营安全。通过界定高速公路隧道出口与互通式立交最小间距的定义并分析隧道出口与互通式立交间距过近路段的交通事故特点，探讨影响高速公路隧道出口与互通式立交最小间距的因素。基于车道变换行为，给出3车道高速公路隧道出口与互通式立交最小间距计算模型，并提出条件受限情况下的最小间距推荐值及安全保障对策。

| Abstract: | As important structures of expressways, the scientific and reasonable space interchanges directly affects route and operating safety of expressways. By defining between tunnels and the minimum space between tunnel outlets and interchanges of expressways and analyzing the features of traffic accidents on road sections for close space between tunnel outlets and interchanges of expressways, this paper probes into the factors influencing the minimum space between tunnel outlets and interchanges of expressways. Based on lane change behaviors, the paper presents a computational model of the minimum space between tunnel outlets and interchanges of expressways and proposes the recommended value of the minimum space and security countermeasures under the limited conditions. |
