摘要：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。

0 Introduction
Trees are the most memorable aspect o±the road—
side planting and are valued as a resource along our
highways and city streets．Whiles trees provide many
benefits，they have also been cited as the major cause
of run—of-roadway (ROR)accidents on the road．
ROR can be describe as a vehicle leaving the road
and encroaching onto the shoulder and beyond and
striking one or more of any number of natural or artifi—
cial objects，such as bridge wails，poles，embankments，
guardrails，parked vehicles，and trees．Trees
impacts are generally fatal and remain the most corn—
monly struck roadside objects in ROR collisions and
thus has been cited as the major cause of run—ofroadway
accidents on the roadway．
A comprehensive review by Dixon and W olf
(2007) on the social，environmental，and eeo．
nomic benefits of trees and their safety risks，found
no indication that roadside trees posed a significant or
constant safety risk． According to the researchers
findings they suggested that，the risk posed by road—
side trees may be blown out of proportion or conflated
with other variables，and should be thoroughly exam—
ined for future designs．Wolf 2006 L2 J conducted a Ha．
tional study of crash data and among others estab—
lished that， the average speed of crashes involving
trees was 22．53 kph faster than the average speed of
all crashes combined．and that the relative risk of a
fatal ROR crash will increase as the speed increased．
Topp(1990) also indicated that appropriate tree
planting and landscaping has a psychological effect of
reducing driving speed ． An NHCRP report by
Neuman et a1．2003 L4 J concluded that obieets located
near the roadside can produce a more severe impact
than obiects away．
Statistics in W ashington State indicate that about
one．．fourth of trafi c accidents are associated with ve．．
hieles running of the road．For example，9，903 out
of the 44．523 vehicular accidents that occurred in
1 994 were related to crashes with roadside fixed ob．
iects．The numbers were 10，158 out of 47，028 in
1995。and l1．903 out of50，635 in 1996．In the U．
S．，single—vehicle run—of-roadway accidents result in
over a million highway crashes with roadside features
every year．Such accidents account for one third of all
hilghway fatalities，with an estimated societal cost of
