Glossary of

car-sharing terms


  • Access badge: Card or electronic device enabling users to access a reserved vehicle.


  • Badge reader: An electronic device capable of reading information stored on an access badge. In the car-sharing context, a badge reader is used to authorize access to reserved vehicles when the badge is presented to the reader. This facilitates a secure, keyless access process for authorized users.


  • Carbon footprint: Measurement of greenhouse gas emissions generated by an activity, product or organization, used to assess the environmental impact of car-sharing.
  • Car-sharing box: Electronic device installed in shared vehicles for access control, reservation management, telemetry data collection and other car-sharing-related functions. This box can also be used for communication between the vehicle and the car-sharing platform.
  • Carpooling: Practice whereby several people share the same vehicle to get to a common location, as opposed to car-sharing, where vehicles are shared but generally used individually.
  • Comprehensive coverage insurance: Extended form of insurance covering damage to the shared vehicle, third parties and passengers.
  • Corporate Mobility Plan: A strategic plan drawn up by a company to optimize employee travel, promote sustainable modes of transport, reduce greenhouse gas emissions and improve overall employee mobility. This plan can include initiatives such as car-sharing, car-pooling, encouraging the use of public transport, promoting walking or cycling, and other measures aimed at rationalizing and greening business travel.


  • Dynamic pricing: A pricing system that varies according to demand, time of day or other factors.
  • Dematerialization of keys: The process by which a vehicle’s traditional physical keys are replaced by electronic or virtual methods. In the context of car-sharing, dematerializing keys can involve using a mobile application or other electronic means to lock, unlock and start the vehicle, thus eliminating the need for physical keys. This offers a practical and secure solution for users.


  • Eco-driving: Driving practice focused on energy efficiency, encouraged in some car-sharing programs.
  • Electric vehicles in car-sharing: Use of electric cars in car-sharing services, helping to reduce carbon emissions.
  • Energy Transition: Process of changing the current energy system towards a more sustainable, environmentally-friendly model. In the context of mobility, energy transition can include the adoption of alternative energy sources, such as vehicle electrification, the use of renewable energies, and other initiatives aimed at reducing the carbon footprint of transport. The energy transition aims to mitigate negative impacts on the environment while guaranteeing a stable and accessible energy supply.


  • Fleet management: A set of procedures and tools used to efficiently administer and maintain a fleet of shared vehicles.
  • Free floating car-sharing: A car-sharing model with no fixed stations, where users can pick up and drop off vehicles anywhere within a defined area. There’s no need to return the vehicle to a specific location.


  • Inter-company car-sharing: A form of car-sharing that involves the pooling of vehicle fleets between different companies. This enables more efficient use of vehicles, and can be implemented for employees from several companies with similar mobility needs.


  • Key box: A mechanism attached to the vehicle as part of car-sharing, providing a secure and accessible means of storing vehicle keys. This device ensures that keys are available to authorized users at the time of booking, facilitating access without the need for a physical meeting.
  • Kilometric rate: Pricing system based on the distance covered during the rental period.


  • Liability coverage insurance: Minimum insurance coverage required for car-sharing, covering damage caused to third parties.
  • LOM Law (Loi d’Orientation des Mobilités): Legislative framework in France designed to promote more sustainable mobility solutions, including provisions for car-sharing and other alternative modes of transport.
  • Logistics management: Planning and organization of vehicle maintenance, repair and distribution operations within the fleet.
  • Loyalty scheme: Program rewarding frequent car-sharing users with benefits such as reduced rates or special offers.


  • Mobility data analysis: Using data collected on vehicle use to improve operational efficiency and anticipate user needs.
  • Mobility package: Financial benefit granted by the employer to encourage more sustainable modes of travel, which may include the use of car-sharing services.
  • Multimodal mobility platform: A system that combines different transport options, including car-sharing, to facilitate the seamless transition from one mode of transport to another.
  • Membership card: Identification card issued to a registered user. Like the access badge, it can be used to access shared vehicles.
  • Mobile application: bespoke software enabling users to search, reserve and unlock car-sharing vehicles from their smartphones.


  • Online reservation: Process of reserving a car-sharing vehicle via an online platform.
  • One-Way car-sharing: A car-sharing model that allows users to pick up a vehicle at a specific location and drop it off at another location. Unlike round-trip car-sharing, there’s no need to return the vehicle to its starting point.


  • Payment badge: Mechanism enabling users to make payments directly from the badge used to access vehicles.
  • Predictive maintenance: Using data to anticipate vehicle maintenance needs before they become major problems.
  • Peer-to-peer (P2P) shared mobility: Model where private vehicle owners share their own cars with other users.


  • Round-trip car-sharing: A car-sharing model where users must return the vehicle to its original location after use. This model is also known as a “loop” because the routes start and end in the same place.


  • Smart Cities: Concept in which information technologies are used to improve quality of life, including the optimization of transport systems and car-sharing.
  • Shared-vehicle fleet: A group of vehicles managed by a car-sharing provider.
  • Shared mobility: A comprehensive concept encompassing various modes of shared transport, including car-sharing, to facilitate urban mobility.
