适应无人配送车的道路非机动车道宽度的思考

Reflection on Width of Road Non-motorized Vehicle Lanes Adapting to Unmanned Delivery Vehicles

摘要:

区别于传统人工驾驶汽车，自动驾驶汽车具有先进的控制感知等技术，对道路工程设计的相关要求也有所不同。研究表明：自动驾驶车辆带来的平稳空间将缩减单车道宽度，道路空间可重新分配给慢行交通。常见无人配送车车辆宽度尺寸在0.9~1.1 m之间，能适应既有规范对非机动车道宽度的要求，但部分城市规范要求的无人配送车车辆宽度尺寸大于三轮车的车身宽度1.25 m，横向摆动和横向安全距离接近机动车，为0.3~0.5 m。从综合安全性、道路空间资源优化等角度来看，建议适当增加非机动车道宽度的建议值，为普通非机动车的行驶提供更安全的空间。研究结果可为适应自动驾驶汽车的道路设计提供参考。

Abstract:

Different from the traditional manual driving vehicles, the self-driving vehicles have the advanced control perception and other technologies, and the relevant requirements for road engineering design have also changed. The research shows that the smooth space brought by self-driving vehicles will reduce the width of single lanes, and the road space can be reallocated to slow traffic. The common width dimensions of unmanned delivery vehicles are 0.9 ~ 1.1 m, which can meet the requirements of the existing regulations for the width of non-motorized vehicle lanes. However, the size of the unmanned delivery vehicle required by some urban regulations is greater than the body width of the tricycle 1.25 m, and the lateral swing and lateral safety distances close to the motor vehicle are 0.3~0.5 m. From the perspective of comprehensive safety and optimization of road space resources, it is suggested to increase the width of non-motorized vehicle lanes appropriately, which provides the safer space for the operation of ordinary non-motorized vehicles. The research results can provide the reference for road design adapted to self-driving vehicles.
