摘　　要：为提高农村客运线路交通紧凑性和降低运营成本,基于紧凑度的测度理论,根据农村地区客运需求对线路方案进行优化研究,分别计算了放射线模式、区域线模式和循环线模式的交通紧凑度;并在满足同样客运需求的条件下,分析了这3种线路模式的运营成本。结果表明:交通紧凑度是循环线模式最高,区域线模式次之,放射线模式最低;而运营成本是循环线模式最低、放射线模式最高。即客运网络越紧凑,其运营成本越低。故建议在对农村公路客运进行线路优化时,线路模式应由放射线向区域线、循环线转变。这样既提高了客运交通网络紧凑度,方便了农民出行,又可以降低运营成本。In order to improve traffic compactness on rural bus route and reduce operation costs, optimization of route scheme was researched according to passenger demand in rural areas based on the theory of compactness measurement. The traffic compactnesses of radiation mode, regional mode and circular mode were calculated respectively, and the operation costs of the three modes were analyzed under the condition of abovementioned passenger demand. The result indicates that （ 1 ） the traffic compactness of circular mode is the highest, that of regional mode is the next, and that of radiation mode is the lowest; （2） the operating cost of circular mode is the lowest, and that of radiation mode is the highest, i.e. more compact traffic network leads to reduction of operation cost. So it is recommended that when optimizing the rural bus routes, the route mode should be transformed from radiation mode to regional and circular modes to improve traffic compactness of rural bus route, facilitate trips of farmers and reduce operation costs.
