Abstract: As a sustainable mode with numerous benefits, cycling offers promoting physical fitness and providing a cost-effective transport option. To promote cycling, cities worldwide are striving to increase cycling usage by improving infrastructure, and network connectivity. Understanding the magnitude of the influence of cycling infrastructure on cycling usage is vital. This paper hence aims to estimate the impact of cycling infrastructure improvement on cycling usage. To this end, a generalised spatial difference-in-differences (GS-DiD) fixed effect spatial lag model is utilised using data collected from bicycle counters in Lyon and Paris. The model allows controlling spatial and temporal unobserved heterogeneity. The results indicate that cycling infrastructure improvement has a positive and statistically significant effect on cycling usage. Additionally, the spatial coefficient was found to be negative and statistically significant, suggesting that an increase in cycling infrastructure usage in neighbouring areas leads to a decrease in infrastructure usage in the area being examined. These findings provide evidence of the positive impact of cycling infrastructure improvement on cycling usage, while also highlighting the importance of considering spatial spillover effects in the analysis.
