【摘要】 为了确定高速公路服务区的合理规模,根据服务区的功能构成,通过对若干服务区平面图设计案例及服务区使用情况的调研,分析了影响服务区规模的主要因素。结果表明,停车场面积是影响服务区总面积的关键;经过现场调查与统计分析,得到了驶入率、高峰率、周转率等主要设计参数值,建立了停车场面积的计算模型,进而计算出各种交通量及车型比例状态下的停车场面积和服务区总面积。更多还原

【Abstract】 In order to determine the reasonable scale of expressway service area,according to the functions of service area,through several cases of the service area graphic design and the service using research,the main factors which influence service scale are analyzed.It is found that:the key that influence the whole service area is the parking area;after on-site investigation and statistical analysis,the main design parameters such as the driving-into rate,the peak-rate and the turnover-rate are obtained.The calculation model of the parking area which is used to calculate the parking area under the proportion of all kinds of traffic and motorcycle type and the whole service area is established.更多还原
