Resource-constrained area is the compound of those regions in which land, energy, local road construction materials are limited, or those regions in which the self-purification ability of air, water are constrained. The geometric and pavement design of road in resource-constrained areas based on the concept of the Cleaner Production aims to reduce emissions, energy consumption and costs over the whole life of the road in these resource-constrained areas including phases of construction, maintenance and usage. Many prospective studies have contributed to theoretical explorations on two aspects of carbon emissions during the whole life of road and geometric and pavement design separately, but there are rarely researches combining and applying these two aspects together, especially on resource-constrained areas. Based on multi-sources and heterogeneous traffic data, this study will construct the interaction and inversion model of road traffic demand forecast. On the theoretical basis of regional road functional combination pedigree and classification selection, and the design basis of regional road traffic demand and operation parameter model, the optimization and compound method of the life-cycle road geometric and pavement design of cleaner production will be developed. Then considering the whole processes of road construction, maintenance and usage, LCA-LCCA combined dynamic optimization model of regional road construction technology, process and timing control will be built. Finally, taking the Guanzhong city-region as study case, these basic theories developed in this study will be verified. Theoretical research on road geometric and pavement design in resource-constrained areas based on the concept of Cleaner Production is of great significance for improving the level of road construction in China, realizing traffic modernization and building transportation power.
资源受限区是土地、能源、筑路材料等资源受限或空气、水的自净能力受限区域的复合。清洁生产的资源受限区道路几何与铺面设计旨在减少该区域道路使用者和工程建设、养护、运行全寿命周期的排放、能耗、成本。诸多前瞻研究分别对全寿命的道路碳排及几何与铺面设计做出了理论探索,但将其结合并应用于资源受限区却很罕见。本研究基于多源异构社会经济、交通、建设、养护、排放数据,构建道路交通需求预测互动与反演模型;以区域道路功能组合谱系与分类选择为理论基础,区域道路交通需求与运行参数模型构建理论为设计基础,形成清洁生产的全寿命路面几何与铺面设计优化复合方法;综合道路建养运全过程,构建LCA与LCCA组合的区域道路建养工艺、工序与时机管控综合动态优化模型。最后以关中平原城市群为研究对象,验证基础理论。研究基于清洁生产理念的资源受限区道路几何与铺面设计理论,对提升我国道路建设水平,实现交通现代化,建设交通强国具有重要意义。
当前道路规划设计理论对城市中心辐射道路区位优势带来的中心区交通量过大、需求难于满足、寻求次优解认识不足。本研究利用GIS 平台整合多源异构交通数据,分析道路交通需求与道路几何和铺面设计的精准配套关系及机理,利用LCA(生命周期环境评估)和LCCA(生命周期成本评估)理论和方法探索基于清洁生产的资源受限区道路几何与铺面设计基础理论,建立基于清洁生产的LCA 和LCCA 评估模型分析交通设施建、养、运全过程服务品质提升的方法,并以关中平原城市群为例,进行实证分析,对推动我国道路交通基础设施可持续发展、交通强国建设和交通现代化具有重大现实意义。
