Changing Habits for Urban Mobility Solutions (CHUMS)  |  @CHUMS_network

 Project Overview

The CHUMS behaviour change strategy includes a carpooling week, conducting personalised travel plans which include carpooling options and providing a mobility jackpot lottery to attract people to carpool. These have all been shown to produce significant behavioural changes in a wide range of places where they have been delivered: increasing car occupancy, reducing car numbers and significantly reducing energy use. This approach will be tested and validated in 5 ‘champion’ cites that represent the scale of carpooling and the diversity of mobility mind-sets across Europe: Craiova (RO), Edinburgh (UK), Leuven (B), Toulouse (F) and Perugia (IT).

The strategic aim of CHUMS is simple – to achieve changes in travel behaviour mind-sets for commuting by:

  • relying on more energy efficient transport and less congestion
  • reducing single occupancy car trips
  • gaining benefits from reduced pressure from cars at work sites, potentially freeing-up valuable parking spaces.

All of the five ‘champion cities’ have existing car-pooling systems, at various stages of maturity, which serve ‘closed’ target groups such as work-places, large employers or universities. Once proven, the application will be equally valid for ‘open’ systems for citizens in general. The project has already developed a European carpooling ‘interest group’ with members from 19 member states and candidate countries; where further take-up of the CHUMS measures will be developed during the project. The 10 fully committed CHUMS partners include mobility behaviour experts, city authorities and carpool operators.

Our Approach

The CHUMS project will be implemented through a package of proven energy efficient transport measures which support carpooling amongst employers and their employees:

  • Hosting of “Carpool week”: the launch of an inaugural “Carpool Week”
  • Provision of mobility jackpot lottery rewards: the launch of the Carpool week reinforced by the award of a bumper mobility jackpot prize to incentivise newly aware car commuters considering carpooling to actually make the switch.
  • Delivery of Personalised Travel Plans including carpooling options: to highlight to car commuters the carpooling options available to them which match their personal circumstances and to emphasise the benefits which are important to those individuals.


  • In December 2015, CHUMS held an interactive seminar (chaired by Paul Curtis from Vectos) in London to share knowledge and expert advice to a wide range of cities interested in implementing the CHUMS measures. Twenty one cities from across Europe attended the seminar, during which they were invited to discuss in groups any challenges or successes they had experienced previously in relation to carpooling.
