面向游客出行需求的景区道路功能等级体系

Scenic area road functional classification system based on tourist travel demand

为了建立中国景区道路功能等级体系,以国内外公路功能等级体系为参考,深入分析景区道路功能分类的原因,阐明景区道路功能的本质。针对景区道路交通特性、景点吸引度和游客需求,分析游客对景区道路功能的需求,提出面向游客出行需求的景区道路功能分类法,将景区道路功能分为景区直通线、景区疏通线、景区连通线3类。分析景区道路等级的影响因素,提取等级划分指标。以单日高峰游客接待量为指标,将景区道路划分为景区直通线Ⅰ级、景区直通线Ⅱ级、景区疏通线Ⅰ级、景区疏通线Ⅱ级、景区连通线5个等级,并确定了道路等级、单日高峰游客接待量和观光车限速之间的关系。研究结果表明:景区直通线Ⅰ、Ⅱ级道路对应的单日高峰游客接待量分别为大于8万人和3.5万~8万人,设计速度分别为60、50 km/h;景区疏通线Ⅰ、Ⅱ级道路对应的单日高峰游客接待量分别为大于6万人和1万~6万人,设计速度分别为40、30 km/h;景区连通线对应的单日高峰游客接待量为小于3.5万人,设计速度为20 km/h。面向游客出行需求的景区道路功能等级体系可为景区道路规划提供重要参考。

In order to establish the functional classification system of scenic area road in China,the reasons of road functional classification and the nature of road function in scenic area were analyzed deeply,based on the reference of highway functional classification system in domestic and abroad.Focusing on traffic characteristics,scenic attraction and tourists demand,the demand of tourists for scenic road function was analyzed.Scenic area road functional classification system based on tourist travel demand was proposed,and scenic area road function was classified into three categories including scenic directional route,scenic distribution route and scenic connecting route.The influencing factors of scenic area road functional classification were analyzed,and the classification index was selected.Taking daily peak tourist reception as an index,scenic area road was classified into five classes including scenic directional route classⅠ,scenic directional route classⅡ,scenic distribution route classⅠ,scenic distribution route classⅡand scenic connecting route.Meanwhile,the relationship among route class,daily peak tourist reception and the speed limit of sightseeing vehicles was established.The results show that the numbers of daily peak tourist reception of scenic directional route classesⅠandⅡare greater than 8×10~4 and 3.5×10~4~8×10~4 people,and the design speeds are 60 and 50 km/h respectively.The numbers of daily peak tourist reception of scenic distribution route classesⅠandⅡare greater than 6×10~4 and 1×10~4~6×10~4 people,and the design speeds are 40 and 30 km/h respectively.The number of daily peak tourist reception of scenic connecting route is less than 3.5×10~4 people,and the design speed is 20 km/h.The scenic area road functional classification system based on tourist travel demand can provide the important reference to scenic area road planning.7 tabs,1 fig,23 refs.
