Ridesharing and Carpooling Dynamics in Urban Transportation

Ridesharing and carpooling have emerged as vital components of sustainable urban mobility, leveraging collective vehicle use to relieve congestion, curb greenhouse-gas emissions and reduce travel costs. Through fixed-schedule carpools and digital platforms that match drivers and passengers in real time, urban dwellers gain alternatives to single-occupancy travel. These schemes interact with public transport networks, offering first- and last-mile connectivity and mitigating gaps in service coverage. Their adoption is shaped by transport policy, incentive design, digital trust mechanisms and socio-behavioural factors such as perceived safety and cost-sharing preferences. Rapid advances in data analytics allow detailed mapping of trip patterns, revealing distinct spatial dynamics between metropolitan cores, intermediate cities and rural hinterlands. Meanwhile, integration into Mobility-as-a-Service ecosystems promises seamless multi-modal journeys, albeit requiring robust real-time information, dynamic routing and regulatory oversight. The global significance of ridesharing lies in its capacity to optimise vehicle occupancy, reduce infrastructure costs and enhance accessibility, offering cities a practical lever to advance low-carbon transport goals.

Ridesharing and Carpooling Dynamics in Urban Transportation publication trend

The graph below shows the total number of articles in ridesharing and carpooling dynamics in urban transportation across all publications each year (not limited to Nature Index journals).

Technical terms

Carpooling: The pre-arranged sharing of a private vehicle by passengers travelling on the same route or to nearby destinations.

Ridesharing: A broader concept encompassing on-demand matching services that pair drivers and passengers via digital platforms for short- or long-distance trips.

Mobility-as-a-Service (MaaS): An integrated transport model combining various mobility options—public transit, cycling, carpooling—through a unified digital interface and payment system.

High-Occupancy Vehicle (HOV) lanes: Traffic lanes reserved for vehicles carrying multiple passengers to incentivise shared travel and reduce congestion.

Vehicle occupancy: The average number of occupants per vehicle, a key metric for measuring the efficiency of shared mobility services.
