摘要

定制化公路客运（CRPT）和类公共汽车铁路客运（BRPT）等新兴城际交通方式正在重构多式联运系统，并对二氧化碳排放产生重大影响。以关中平原城市群为例，建立了城际多式联运出行碳排放的量化方法。将“出行碳流”概念作为一个动态的空间排放网络引入。它通过乘客的移动追踪二氧化碳的扩散。建立了一个动态模型来描述多式联运系统的排放模式。设计了CRPT和BRPT的多种规划场景。通过情景分析，对这些新兴城际出行方式的脱碳潜力进行了评价。结果表明，私家车出行仍然是碳排放的主要来源。碳流强度受基础设施配置和出行需求的影响，呈现出从城市核心到周边地区的空间辐射模式。CRPT和BRPT有助于增强城市群间的减排和分配公平。

The impact of emerging intercity travel modes on transportation decarbonization

Emerging intercity travel modes, such as Customized Road Passenger Transport (CRPT) and Bus-like Railway Passenger Transport (BRPT), are restructuring multimodal transportation systems and exerting significant impacts on CO2 emissions. Using the Guan-Zhong Plain Urban Agglomeration as a case, a methodology is developed to quantify carbon emissions from intercity multimodal travel. The concept of "travel carbon flow" is introduced as a dynamic, spatial-emission network. It traces CO₂ dispersion through passenger movements. A dynamic model is constructed to describe emission patterns within the multimodal transportation system. Multiple planning scenarios for CRPT and BRPT are designed. Scenario analysis is used to evaluate the decarbonization potential of these emerging intercity travel modes. The results demonstrate that private vehicle travel remains the primary contributor to carbon emissions. Carbon flow intensity is shaped by infrastructure configuration and travel demand, exhibiting spatially radiating patterns from urban cores to peripheral zones. CRPT and BRPT contribute to enhanced emission reductions and distributional equity across the urban agglomeration.

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
