基于行车连续性的合理公路限速方案研究

针对目前我国公路限速方面存在的问题，从行车连续性的角度出发，分析公路线形连续与运行速度连续两者之间的关系，以及影响行车连续性的影响因素，由此提出公路线形连续性评价标准，并结合某2级公路线形连续性分析与评价结果验证评价标准的合理性，进而根据该标准对新建和已建公路分别提出相应的限速方案。

Research on Reasonable Highway Speed Control Schemes Based on Continuity of Driving

Aiming at the existing problems in highway speed control in China at present, this paper analyzes the relationship between highway alignment consistency and operating speed continuity from the viewpoint of continuity of driving and the influence factors for continuity of driving. On this basis the paper proposes the evaluation criteria for highway alignment consistency and analyzes and evaluates results in combination with some grade 2 highway alignment consistency to verify rationality of evaluation criterion, and further puts forward corresponding speed control schemes for new and existing highways respectively in accordance with this criterion.
