【摘要】：研究目的:近年来,厦门市民经常投诉文兴隧道最高限速偏低,通行效率不高,而国内尚未有提高限速的相关规范。本文研究文兴隧道能否提高限速,并尝试从中提炼出提高道路限速研究的技术路线。研究结论:(1)通过几何线形指标分析、实测运行速度分析,发现文兴隧道全线整体提高限速不可行,但可区间提高限速;(2)建议文兴隧道直线段采用分车道分车型限速方式,小型车提高限速至60 km/h,大型车提高限速至50 km/h,提高限速段的照明、通风条件、标志、标线、标牌等应按照其最高限速值(60 km/h)进行校验;(3)提高道路限速研究建议技术路线:首先对拟提高限速路段按拟提高的限速进行规范符合性检查;结合限速区最小长度及过渡段最小长度,检查拟提高限速段范围及长度是否满足要求;在对运行速度值进行分析和修正的基础上,提出拟提高限速值,有条件地采用实测运行速度,条件不足时,采用模拟运行速度;检查提高限速段的照明、通风条件、标志、标线、标牌等条件是否满足此段最高限速的相关要求,不满足的要进行完善;(4)该研究成果可用于公路和城市道路提高限速研究。
[Abstract]:Research objective: in recent years, Xiamen citizens often complain that the maximum speed limit of Wenxing Tunnel is low, and the traffic efficiency is not high, but there are no relevant rules to improve the speed limit in China. And try to extract the technical route from which to improve the speed limit of road. Conclusion: 1) through the analysis of geometric linear index and the analysis of actual running speed, it is found that it is not feasible for the whole line of Wenxing Tunnel to increase the speed limit as a whole. However, it is suggested that in the straight section of the Wenxing Tunnel, the speed limit should be increased to 60 km / h for small cars and 50 km / h for large vehicles, so as to improve the lighting, ventilation conditions, signs and marking of the speed limit section. The signs should be checked according to its maximum speed limit value of 60 km / h)) the research on improving the speed limit of the road should be carried out and the technical route should be suggested: first of all, the conformity of the proposed speed limit section should be checked according to the speed limit to be increased; Combined with the minimum length of the speed limit zone and the minimum length of the transition section, it is checked whether the range and length of the speed limit section to be increased meets the requirements, and on the basis of the analysis and correction of the running speed value, it is proposed to increase the speed limit value. The actual operating speed is used conditionally, and when the conditions are insufficient, the simulated running speed is adopted; check whether the lighting, ventilation conditions, signs, marks, signs, signs and other conditions of the speed limit section can meet the relevant requirements of the maximum speed limit for this section, The research results can be used to improve the speed limit of highway and urban road.
