Sustainability, Journal Year: 2025, Volume and Issue: 17(10), P. 4735 - 4735

Published: May 21, 2025

The fast growth of global e-commerce has made cargo transportation and package delivery more important in cities. However, the limited resources for urban road traffic have logistics distribution less efficient. movement toward green sustainability, energy conservation, emission reduction heightened awareness necessity to enhance mobility transportation. This work further investigates optimization hub locations based on subway systems, informed by research modes current state underground logistics. presents two unique models: a metro-integrated evaluation model location model, aimed at identifying ideal station establishing center with minimal total costs. A heuristic method, jellyfish search algorithm (JS) particular, is carefully explained order find good answer model. From an empirical perspective, district Chaoyang Beijing, China, was taken as case simulate progress metro city hub, minimizing logistical results indicate that system can be used deliveries, proposed method are very useful improving hubs city. Consequently, when facilities allow, we should fully utilize extensive capacity transit efficient, environmentally friendly, sustainable advancement

Measuring Effectiveness of Metro-Based Underground Logistics System in Sustaining City Logistics Performance During Public Health Emergencies: A Case Study of Shanghai

Transportation Research Record Journal of the Transportation Research Board, Journal Year: 2024, Volume and Issue: 2678(9), P. 724 - 748

Published: Feb. 25, 2024

City logistics performance (CLP) is being increasingly challenged by public health emergencies and relevant mobility restriction policies. This paper introduces a novel urban contactless delivery measure incorporating the metro-based underground system (M-ULS) “Pandemic Thruport” (P-Thruport) concept to encounter service failure during pandemic outbreaks. solution proposed utilize redundant rail transit capacity move goods efficiently collectively from outskirts in-city customer destinations. To assess effect of on CLP, two interacting dynamics models are developed, where supply–demand relationships, operation process, CLP evaluation indicators (e.g., time delay, costs, infection model, benefits) comprised. The COVID-19 outbreaks in Shanghai March May 2022, were taken as case evaluate variation under four different scenarios associated with dynamic implementation M-ULS conditions. Results show that new conducive lowering risks activities improving freight transport efficiency. Compared trucking mode, M-ULS’s advantages reflect cost-saving capability. Moreover, sustainable improvement can be achieved balancing operations road-based services through incentive policy adjustment.

Node location of bi-level urban metro-based ground-underground logistics distribution

Multimodal Transportation, Journal Year: 2023, Volume and Issue: 3(1), P. 100119 - 100119

Published: Dec. 11, 2023

Metro-based underground logistics (M-ULS) can relieve the pressure of urban traffic and avert road congestion through coordinating with ground system. A bi-level node location model is proposed based on ground-underground distribution mode. The cost delivery pickup from perspective service companies customers are minimized as upper lower objectives. Since belonged to NP-hard problem, simulated annealing algorithm (SA algorithm) whose new solution generation part was improved according characteristics used solve problem. In case analysis part, nodes customer points close Nanjing Metro Line 3 were selected verify validity algorithm. result shows that SA outperformed in taking less iteration times obtaining better solutions. total transportation system be reduced by 21.7 % optimized plan, 63.6 distance replaced transportation, such results also obtained when cargo demand increases 1.5 2 times, which verifies advantages M-ULS reducing truck emission cost.

The Integration of Urban Freight in Public Transportation: A Systematic Literature Review

Sustainability, Journal Year: 2024, Volume and Issue: 16(13), P. 5286 - 5286

Published: June 21, 2024

Urban logistics face growing complexity as cities seek sustainable development pathways; one solution is integrating freight transportation with public transit. The purpose of this study to evaluate current practices, identify gaps, and highlight opportunities for advancement in field. Through a comprehensive literature review guided by four research questions, evaluates methodologies, vehicle choices, the application intermodal containers, shared use infrastructure delivery. A meticulous search methodology was employed select references, which were then analyzed classified into two main tables. Findings reveal progression from initial pilot projects cost analyses sophisticated planning optimization challenges, focus on metro networks buses. This uncovers predilection certain types, utilization varied modes, underexplored container use, an emerging emphasis transshipment operations. integration within urban settings identified dynamic diversifying field, significant potential contributing development. We outline nine areas future research, including incorporation external costs congestion effects models, exploration unmanned vehicles, thereby laying groundwork more inclusive efficient solutions.
