Modelling Urban Delivery Trip Chains from A Low Carbon Perspective

In recent years, the scale of the urban delivery industry has been expanding and its influence has become increasingly significant. Although urban delivery brings great convenience, it also introduces various problems, such as increased traffic congestion and exhaust emissions. This paper proposes two calculation models for carbon emission of urban delivery vehicle travel chain, including the carbon emission calculation model based on GPS data and the carbon emission calculation model based on travel chain characteristics. The research results show that the results of the two calculation methods are consistent, which can help the research on carbon emissions of urban delivery vehicles enrich relevant theoretical research results, and provide a model reference for the development of relevant practices.
