Adaptation of economic intervention effect on mobility model in Far East environment

Abstract

Mobility is a key pillar of the 21^st century, connecting people and information while presenting sustainability challenges. This paper aims to evaluate the impact of economic interventions on urban mobility, specifically through the introduction of parking fees in Jinan, China. The study employs a refined mobility model that categorises road usage into downtown, city, rural, and motorway environments and adapts European baseline data to the Far Eastern context. Data and methods include the development of a model measuring individual utility by average speed and social utility by CO₂ emissions per passenger kilometre. The model is adapted to reflect Far Eastern cities’ unique urbanisation and energy mix. Results indicate that the introduction of parking fees in Jinan has significantly reduced traffic congestion, increased public transportation usage by 20%, and decreased CO₂ emissions by 8%. The tiered pricing system has improved urban space utilisation and economic efficiency. In conclusion, the study highlights the effectiveness of economic tools in promoting sustainable urban mobility and underscores the need for region-specific adaptations. Future research should explore additional economic interventions and expand the model’s applicability to other regions.
