摘要

货运对于大都市地区的经济竞争力和长期生存能力至关重要。然而,货运也是产生负面外部效应(包括温室气体排放)最多的活动之一。研究货物运输、土地利用和需求管理之间的关系,对于推广开明的政策,增加供应链的社会效益,同时避免其不良影响(如气候变化)至关重要。然而,公共规划者可用于将货运纳入分析的工具非常有限。在此背景下,本文旨在强调货运需求管理策略和货运效率高的土地利用方式对提高城市货运可达性的影响。在这项研究中,作者提出了一个基于两种可达性测量方法(基于等时线的模型和基于重力的模型)的货运可达性框架,以分析纽约市大都会统计区内零售贸易、住宿和餐饮服务、运输和仓储以及电子商务四个行业货运可达性的时空变化。结果表明,可达性措施为政策制定提供了有价值的见解,特别是针对土地使用(如仓库选址)的政策,以及旨在将货运车辆交通转移到交通拥堵较少时段的政策。

Assessment of freight accessibility in New York City: A spatial-temporal approach

Freight transportation is critical to metropolitan regions' economic competitiveness and long-term viability. However, it is one of the activities that produce the most negative externalities, including greenhouse gas emissions. The study of the relationship between freight transportation, land use, and demand management is critical for promoting enlightened policies that increase the social benefits of supply chains while avoiding their undesirable effects, such as climate change. Nonetheless, the tools available to public planners for incorporating freight transportation into their analyses are limited. In this context, this paper aims to highlight the impact that freight demand management strategies and freight-efficient land uses can have on increasing urban freight accessibility. In this study, the authors suggest a freight accessibility framework based on two measures of accessibility (an isochrone-based model and a gravity-based model) to analyze the spatiotemporal variation of freight accessibility in the New York City metropolitan statistical area for four sectors—retail trade, accommodation and food services, transportation and warehousing, and e-commerce. The results indicate that accessibility measures provide valuable insights towards policymaking, particularly to policies that target land use (e.g., location of warehouses), and policies that aim to shift the traffic of freight vehicles to periods with less traffic congestion.

期刊介绍: A major resurgence has occurred in transport geography in the wake of political and policy changes, huge transport infrastructure projects and responses to urban traffic congestion. The Journal of Transport Geography provides a central focus for developments in this rapidly expanding sub-discipline.
