Synergy of Road Network Planning Indices on Central Retail District Pedestrian Evacuation Efficiency

“…Excluding the similar samples of central business districts (CBD), recreational business districts (RBD) and urban complexes, nine CRDs at city level were selected as the research objects. These objects are of strip and mesh CRD types, which have obvious typological characteristics for transportation and distribution [26].…”

“…Jiang (2022) [25] took Dartford, Kent County, UK, as the research object and emphasized the influence of road width and road type on the urban road network form. In addition, [26] pointed out that the CRD transportation and distribution relationship is special, and the planning indices of primary and secondary road networks should be studied separately.…”

“…The primary road of a CRD should be a "broad width" pedestrian form according to the analysis results of optimal road grade level. A CRD primary road is the product of an urbanization process, which mainly shows two forms: walking and mixed-traffic commercial streets, according to different development stages [26]. Concessions at the bottom of building facades along the street and three-dimensional walking systems can establish continuous pedestrian roads, and ensure the primary road width is approximately 30.1~40.0 m.…”
