摘　　要：针对高速公路互通式立体交叉变速车道的设计问题,理论分析了汽车在加速、减速过程中所需变速车道长度的特征。对影响变速车道设计的各种因素进行综合考虑。基于变速车道相关的交通事故预测模型和成本模型,设计了安全和经济性均衡的高速公路互通式立体交叉变速车道。通过统计数据,对不同车道所设计的变速车道合理长度进行验证。验证结果表明,设计方案能够有效减少汽车在变速车道上的事故发生概率。该成果对相关领域的研究具有理论价值和实践指导意义。For the design of variable speed lanes in highway interchanges, the characteristics of the required variable speed lane length during acceleration and deceleration of cars are theoretically analyzed. Various factors affecting the design of the variable speed lane are considered comprehensively. Based on the traffic accident prediction model and cost model related to the variable speed lane, a highway interchange variable speed lane with balanced safety and economy is designed. The reasonable lengths of the lanes designed for different lanes are verified by statistical data. The validation results show that the design solution can effectively reduce the accident probability of vehicles in the variable speed lanes. The results are of theoretical value and practical guidance for research in related fields.
