This paper established the typical forms of central retail district (CRD) road networks in terms of block form, network structure and road grade, taking China as an example. The experiment was designed using the orthogonal design of experiment (ODOE) method and quantified the evacuation time under different road network planning indices levels through the Anylogic simulation platform. Using range and variance analysis methods, the synergy of network density, network connectivity, road type and road width on pedestrian evacuation efficiency were studied from the perspectives of significance, importance and optimal level. The results showed that the type of CRD will affect the importance of network planning indices, and that the network connectivity is insignificant (P 0.477\/0.581) in synergy; networks with wide pedestrian primary roads (30.1~40.0 m), medium secondary roads (3.1~5.0 m\/side) and high density (11.0~13.0 km\/km2) have the highest evacuation efficiency. From the perspective of evacuees, this paper put forward urban design implications on CRD road networks to improve their capacity for disaster prevention and reduction.<\/jats:p>","DOI":"10.3390\/ijgi12060239","type":"journal-article","created":{"date-parts":[[2023,6,9]],"date-time":"2023-06-09T08:37:33Z","timestamp":1686299853000},"page":"239","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Synergy of Road Network Planning Indices on Central Retail District Pedestrian Evacuation Efficiency"],"prefix":"10.3390","volume":"12","author":[{"given":"Gen","family":"Yang","sequence":"first","affiliation":[{"name":"School of Architecture and Urban Planning, Chongqing University, Chongqing 400045, China"}]},{"given":"Tiejun","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Architecture and Urban Planning, Chongqing University, Chongqing 400045, China"}]},{"given":"Mingxi","family":"Peng","sequence":"additional","affiliation":[{"name":"The Department of Smart Urban Design, Chongqing Jianzhu College, Chongqing 400072, China"}]},{"given":"Zhigang","family":"Wang","sequence":"additional","affiliation":[{"name":"The Department of Smart Urban Design, Chongqing Jianzhu College, Chongqing 400072, China"}]},{"given":"Dachuan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Southwest University of Science and Technology, Mianyang 621010, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,9]]},"reference":[{"key":"ref_1","unstructured":"United Nations Office for Disaster Risk Reduction (2022).
