While prior studies have shown that battery-to-battery in-motion charging (B2BIC) effectively reduces travel delays on single highways, its optimization across intercity highway networks remains unexplored. Addressing this gap, we develop a mixed-integer nonlinear programming (MINLP) model and reformulate it into a mixed-integer linear programming (MILP) model using a discretization method to enhance solvability. Case studies based on Chinese highway data validate the proposed approach. Key findings include: (1) Deployed energy-providing vehicles (EPVs) can operate continuously for over 18 hours without intermediate charging, with each delivering 100–200 kWh of energy per day using a 350 kWh battery; (2) Increasing the EPV fleet size and depot coverage significantly boosts energy delivery and reduces average EV travel time, though marginal benefits diminish beyond approximately 90 EPVs; (3) Larger EPV battery capacities further improve system performance (higher energy output and greater travel time reduction), while expanding from 3 to 7 depots has a limited impact under constant demand. These findings suggest that integrating B2BIC services into future EV charging infrastructures could substantially enhance system resilience and scalability, providing valuable guidance for planners and policymakers.</div></div>","PeriodicalId":48974,"journal":{"name":"Transportation Letters-The International Journal of Transportation Research","volume":"18 2","pages":"Pages 429-445"},"PeriodicalIF":3.3,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147427493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This framework comprises three key steps: 1) identifying oversaturation-contributing demand using passive travel data; 2) filtering key divertible passengers and estimating their probability of switching to UAM; and 3) optimizing UAM shuttle routes to meet section flow constraints at minimal cost. Using Shenzhen, China, as a case study, we assess the feasibility of UAM under different pricing schemes, demand levels, and eVTOL vehicle types. The findings indicate that diversion effectiveness is highly sensitive to pricing schemes, especially mileage charges. Excessive charges hinder diversion and prevent compliance with section flow constraints. The feasibility of UAM in achieving alleviation goals is also limited by demand levels, becoming ineffective at handling demand exceeding 1.5 times the benchmark.
