Introducing John Rawls’s theory of justice, this study develops an equitable road network design model that maximizes accessibility for regions with poor current accessibility. The bilevel integer optimization allocates a limited budget across candidate links, aiming for a fairer accessibility distribution. A case study on Iran’s interprovincial network shows low-accessibility groups decline from 30% to 11%, and the min-to-max accessibility ratio rises from 3.09% to 14.39%.","cbCaibe3oUeb56It","https://ap.wps.com/l/cbCaibe3oUeb56It","pdf",1196812,1,9,"English","# Introduction\n## Problem Background and Motivation\n## Related Work and Objectives\n## Justice-Oriented Network Design Framework","[{\"question\":\"Why does the study focus on equitable allocation of road network development budgets?\",\"answer\":\"Budgets are commonly distributed in ways that favor higher-welfare regions, which increases socioeconomic gaps and leaves suburbs with fewer benefits from transportation services.\"},{\"question\":\"How does Rawls’s social justice theory shape the proposed road network model?\",\"answer\":\"The model is built around maximizing accessibility benefits for the poorest groups, prioritizing regions that currently have low accessibility to achieve a more balanced distribution.\"},{\"question\":\"What optimization method is used in the model and what does it optimize?\",\"answer\":\"The model is formulated as a bilevel integer optimization problem, allocating a limited budget to candidate network links to improve accessibility equity across regions.\"}]",1779224525,23,{"code":4,"msg":27,"data":28},"ok",{"site_id":29,"language":30,"slug":31,"title":13,"keywords":32,"description":14,"schema_data":33,"social_meta":84,"head_meta":86,"extra_data":88,"updated_unix":24},105,"en","designing-a-road-network-using-john-rawlss-social-justice-approach","",{"@graph":34,"@context":83},[35,52,66],{"@type":36,"itemListElement":37},"BreadcrumbList",[38,42,46,49],{"item":39,"name":40,"@type":41,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":43,"name":44,"@type":41,"position":45},"https://docshare.wps.com/document/","Document",2,{"item":47,"name":12,"@type":41,"position":48},"https://docshare.wps.com/document/research-report/",3,{"item":50,"name":13,"@type":41,"position":51},"https://docshare.wps.com/document/designing-a-road-network-using-john-rawlss-social-justice-approach/31248/",4,{"url":50,"name":13,"@type":53,"author":54,"headline":13,"publisher":56,"fileFormat":59,"description":14,"dateModified":60,"datePublished":60,"encodingFormat":59,"isAccessibleForFree":61,"interactionStatistic":62},"DigitalDocument",{"name":9,"@type":55},"Person",{"url":39,"name":57,"@type":58},"DocShare","Organization","application/pdf","2026-05-19",true,{"@type":63,"interactionType":64,"userInteractionCount":4},"InteractionCounter",{"@type":65},"ViewAction",{"@type":67,"mainEntity":68},"FAQPage",[69,75,79],{"name":70,"@type":71,"acceptedAnswer":72},"Why does the study focus on equitable allocation of road network development budgets?","Question",{"text":73,"@type":74},"Budgets are commonly distributed in ways that favor higher-welfare regions, which increases socioeconomic gaps and leaves suburbs with fewer benefits from transportation services.","Answer",{"name":76,"@type":71,"acceptedAnswer":77},"How does Rawls’s social justice theory shape the proposed road network model?",{"text":78,"@type":74},"The model is built around maximizing accessibility benefits for the poorest groups, prioritizing regions that currently have low accessibility to achieve a more balanced distribution.",{"name":80,"@type":71,"acceptedAnswer":81},"What optimization method is used in the model and what does it optimize?",{"text":82,"@type":74},"The model is formulated as a bilevel integer optimization problem, allocating a limited budget to candidate network links to improve accessibility equity across regions.","https://schema.org",{"og:url":50,"og:type":85,"og:title":13,"og:site_name":57,"og:description":14},"article",{"robots":87,"canonical":50},"index,follow",{"doc_id":7,"site_id":29}]
