行道树的种植及其对冲出道路交通事故的影响

摘要

Roadside trees as the fulcrum of road landscape design has been cited as the major cause of run-off-roadway(ROR)accidents on the roadway. This is because roadside trees are the most hit fixed object during ROR accidents,hence many researchers have recommended for its outright removal from the roadside to create e-nough clear zone. This paper researched and provided insight into the intertwine problem of the impact of land-scape tree plantings on ROR accidents by analyzing some statistically available data from other researchers and a-gencies. This paper asserts that,roadside trees are just the final recipient of ROR crash and that establishing the reasons for which the vehicles leave the road is very imperative to finding a better solution to ROR accidents. More so,systematically encoding safety measures in the design of the roadway and its landscape features can sig-nificantly influence driver behavior and subsequently reduce the frequency and severity of ROR accidents.%作为道路景观设计的一个分支，行道树的设计被列为车辆冲出路外（ROR）交通事故的主要原因。因为在ROR 事故中，行道树是被撞击最多的固定物体，因此，许多研究人员建议取消行道树的种植，以创造足够清晰的区域。通过分析其它研究人员和机构统计的可用数据，研究并深入探讨了行道树的种植对 ROR 事故的影响。结果表明，行道树只是 ROR 撞车事故的最终接收者。我们迫切需要确定车辆冲出道路的原因，以制定解决 ROR事故的最佳方案。此外，道路设计和道路景观因素中对安全措施进行系统编码可以显著影响驾驶人员的驾驶行为，并由此降低 ROR 事故的发生频率和严重程度。
