摘　　要：随着我国公路网的建设与完善,高速公路已成为物流和客流的主要载体之一,对地区国民经济和社会发展起着至关重要的作用。根据河南省公路系统的实际情况,基于通行路径中时间消耗测度,利用非欧氏空间中最佳路径算法,对单位时间内河南省高速公路服务区域覆盖范围进行定量评价。研究结果表明,河南省高速公路服务覆盖率差别较大,覆盖率较高的地区,主要集中在经济相对发达的河南省中部,外围地区覆盖率相对较低,有4块总面积为29 596 km2的地区急需完善高速公路布局和修建高水平高速引线。With the traffic network running into perfection, the highway network has been becoming one of the primary carriers for logistics and passenger flow, and playing a crucial role in the development of economy and society. Based on the conditions of Henan traffic network system and time-cost, using the NEDS algorithm in the Non-Euclidean space, this paper quantitatively evaluated the serving area of highways. The research showed that the rates of serving area for a given time, have largely diversity, the districts with higher rate mainly concentrate on the middle area of Henan, where also have higher development level of eeonomy and society, and in the margin region the rate is very lower. There are four districts with 29 596 km^2 , requiring the optimization of the highway system or improving the ordinary traffic system as soon as possible.
