概括
摩托两轮车乘客在印度的城市没有信号的十字路口面临高撞车风险. 较长的间隙接收时间和特定的交叉路口设计,如交通岛屿,可以减少这些风险对脆弱的道路使用者.
科学领域:
- 交通安全 交通安全 交通安全
- 运输工程 运输工程
- 易受攻击的道路使用者行为
背景情况:
- 在印度的道路交通事故中,机动两轮车 (MTW) 占主导地位,特别是在没有信号的十字路口.
- 在印度,超过60%的交通事故死亡人数涉及弱势道路使用者.
- 没有信号的十字路口是弱势道路使用者的关键事故热点.
研究的目的:
- 了解印度城市无信号交叉路口的机动两轮车 (MTW) 驾驶者的行为.
- 为了确定影响MTW骑手碰撞概率的因素.
- 评估不同交叉路口设计对MTW安全性的有效性.
主要方法:
- 利用入侵后的时间来评估MTW用户的交通冲突.
- 运用极端价值理论来计算碰撞概率.
- 开发了Tobit和分组随机参数Tobit回归模型,使用来自印度苏拉特的数据.
主要成果:
- MTW车手表现出最短的间隔验收时间,增加与汽车和重型车辆的冲突.
- MTWs具有最高的崩率;组合随机参数托比特回归更好的模型崩概率.
- 在转时,MTW车手面临更高的撞车风险;根据交叉路口腿数,中央交通岛屿对撞车率的影响各不相同.
结论:
- 高速公路撞车率受到交通量,组成和交叉路口特征的显著影响.
- 对MTW骑手来说,增加差距接受时间可能会导致降低碰撞率.
- 反制策略,特别是那些涉及中央交通岛屿的反制策略,需要对特定地点进行评估,因为对三脚和四脚交叉路口的影响各不相同.

Sight Distance in a Vertical Curve
43
Sight distance on vertical curves is critical in roadway design. It ensures drivers can see far enough ahead to identify and respond to hazards effectively. This directly impacts safety, driver comfort, and the overall efficiency of the transportation network.Vertical curves are classified into crest and sag curves based on their geometry. For crest curves, sight distance is determined by the line of sight between a driver's eye and a small object on the road's surface. Design parameters for...
