Impact of Car-Sharing and Ridesourcing on Public Transport Use: Attitudes, Preferences, and Future Intentions Regarding Sustainable Urban Mobility in the Post-Soviet City

Abstract

The impacts of ICT-based mobility services vary in different cities, depending on socioeconomic, urban form, and cultural parameters. The impacts of car-sharing and ridesourcing on public transport have not been investigated appropriately in post-Soviet Union cities. This study presents exploratory evidence on how ridesourcing and car-sharing affect public transport usage in Moscow. Additionally, it studies how demographics, spatial parameters, attitudes, and travel preferences influence the frequency of use of ridesourcing and car-sharing in Moscow. An online mobility survey was conducted at the beginning of 2020 among respondents (sample size is 777) in the Moscow agglomeration. Overall, 66% of ridesourcing users shifted from public transport to these mobility services, which shows the substitutional impact of ridesourcing on public transport. Additionally, the logit model indicates that the regular use of ridesourcing negatively correlates with the regular use of buses/trams/trolleybuses in Moscow. The impact of car-sharing on public transport seems less substitutional and more complementary than the impact of ridesourcing. Overall, 40% of car-sharing users would replace their last car-sharing trip with public transport if car-sharing was unavailable. Moreover, the logit model indicates a positive association between the regular use of car-sharing and the use of buses/trams/trolleybuses. Moreover, the modal split analysis shows a bigger share of public transport use and walking than car use among citizens’ urban journeys in Moscow.

“…Utilizing an online survey to understand the impact of automated vehicles on users 'preference for transport mode, Pakusch et al [36] discovered that automated vehicles for car sharing could substitute the demand for public transport. Similarly, the survey's results analyzed by Mostofi [37] showed a substitution effect of ride-sourcing of 30 % for private cars and 24 % for public transport, while Tarnovetckaia et al [38] concluded that the combination of ride-sourcing and car sharing would shift 66 % of the public transport demand in Moscow.…”

“…To estimate user-related effects, one paper used empirical data [34], four papers used a survey [36][37][38][39], and two papers used a field experiment [36,40]. The changed practice effect is analyzed in three studies [34,35] [39], while five studies concentrated on the substitution effect [34,[36][37][38]40].…”

Renewable Energy Utilization and Environmental Pollution Control in the New City Area Mamminasata Metropolitan, Indonesia

“…The urban spatial integration has an impact on population mobility and its effect on increasing the flow of goods and passengers transport. Spatial integration has an impact on population mobility services based on information and communication technology in relation to socio-economic conditions, urban forms, and culture (Tarnovetckaia and Mostofi, 2022;Che et al, 2022). Thus, the pattern of population mobility from the direction of new urban areas to activity centers which tends to increase over time has an impact on the complexity of the Mamminasata Metropolitan urban transportation system.…”

“…Sustainability in city logistics is also promoted by using state-of-the-art advances in carsharing and ridesharing systems. The raise of carsharing services can decrease the number of private cars and change travel behaviors toward sustainability [30]. As a matter of fact, carsharing users can take advantage of using private cars without the responsibility and cost associated with car ownership [31].…”
