Will CHUMS work at your site?

The CHUMS project has developed a tool which establishes, for any candidate site, the current carpooling status, estimates the potential impact of introducing CHUMS and identifies the supporting measures which are most likely to maximise the impact of CHUMS.

The success of a carpooling scheme at a particular location, and the subsequent effectiveness of introducing the CHUMS measures to a carpooling scheme, depends on many factors. While a number of these cannot be influenced by those responsible for setting up or managing a carpool scheme, there are others which carpool/mobility managers can exert influence over and which can have a significant effect on the success or otherwise of the schemes/measures introduced.

To aid sites which are considering introducing a carpool scheme or would like to implement the CHUMS measures to an existing carpool scheme, the CHUMS project have developed a simple and easy to use tool which enables candidate sites to quickly assess their suitability for carpooling and to indicate (in a very general manner) the likely impacts of introducing the CHUMS measures. It also identifies supporting measures which the carpool/mobility managers should consider to maximise the impact of implementing CHUMS.

Following extensive review of literature supported by surveys with CHUMS partner sites and carpool service providers, eight factors were identified as having the greatest bearing on the suitability of a particular location for carpooling. These are shown below.


The answers to a number of questions related to each factor give a measure of the current status for that factor at the site in question (the questions are weighted according to their relative importance).

An example of the questions for one of these factors is provided below for the ‘Carpool status in your city/region’. The full set of questions for all factors can be viewed by downloading the tool at the bottom of this page.

news4bOnce the user has answered the simple checkbox questions for all 8 factors (37 questions in total), which takes no more than 5 to 10 minutes to complete, the tool produces a number of useful outputs informed by the site specific information provided by the user:

  1. A spider chart illustrating, at a glance, the contextual situation in their country/region and at their candidate site. The eight spokes of the web represent the factors which have the greatest bearing on the suitability of a particular location for carpooling. This allows the user to quickly identify the factors which are currently limiting successful carpooling initiatives; i.e. those which are closest to the centre of the web.
  2. An impact chart which indicates the potential impact that introducing the CHUMS measures is likely to have at their site based on the contextual information provided. The position of the 5 CHUMS demonstration sites (prior to introducing CHUMS) has been mapped onto this, allowing users of the tool to gauge how their site compares.
  3. A text summary of the general standing and support for carpooling, current status of carpooling and suitability of the candidate site for increasing carpooling. A basic assessment of the potential impact from introducing CHUMS measures is provided along with a list of supporting measures which should be considered to improve the likely impact of introducing CHUMS measures.

The benefit of this tool is that follower sites or future candidate CHUMS sites can use the tool to quickly establish the suitability of introducing CHUMS at a particular site, and receive suggestions on supporting measures which would maximise the impacts of CHUMS.

The tool is available for download from the link below. Feel free to try it out for your own candidate site.
