MODUM Field Trials: Step by Step


Step 1: Trial participants were recruited

Participants were recruited through a media campaign in the two trial sites Nottingham and Sofia. Within these campaigns posters, flyers and internet banners were used to direct prospective participants to the web based registration page (www.transportinnovations.info).

Users, having registered, received a confirmation email detailing the two phases of the trial and how they can qualify for rewards including a month free travel by public transport and entry into a draw for a smart phone.

15 smart phones (at both sites) were available for loan to participants without access to a device with appropriate capabilities. To ensure the return of these devices they were made available primarily to participants affiliated with the project, such as ticket booth operators and guards.


Step 2: Participants used the MODUM mobile application and online dashboard

The MODUM mobile application operates on mobile devices with the Android operating system. It is available from the Google Play store free of charge. (During the trial application in Sofia a Bulgarian version of the application was available from the Vivacom app store  free of charge)

During phase 1 users loged in to the application, and selected their direction of travel (from or to work for example) before they started the journey. The application automatically tracked the journey. When the user reached her/his destination (i.e. when the user was within 100m of the destination) the application waited for 3 minutes before stopping the tracking of the journey. Then the application requested the user to confirmation that this journey had resembled a typical commute (as specified by the user in the registration-form for the field trial).

During phase 2 users loged in to the application and selected their direction of travel (as in phase 1). However, in phase 2, after selection of the direction of travel users were presented with the fastest and greenest route to their destination. These routes were calculated by the MODUM system taking into consideration the user’s travel preferences and current traffic conditions. The two route-suggestions included a brief description of the journey features, such as transport mode(s) to be used, expected emissions and trip duration. In addition to the route suggestions, also an overview of the user’s average weekly C02 emissions per phase was given. The following figure depicts the application dialog presented to the user before the selection of a route in phase 2 of the MODUM field trial.

When the user has selected either the “Greenest route” or the “Fastest route”, the application presents a summary of the route, where the user can see more details by selecting a specific section of the route.

Having selected ‘begin’ the user takes the journey as guided by the application via a map interface. The map has location and orientation adjusting functions to facilitate easy navigation of the application and the route.

Once the user has arrived at the destination the application automatically stops tracking the journey, and request the user to confirm that she/he has taken the route as suggested, and in case the user deviated from the suggested route, a brief explanation of the reason for deviation is requested.

During the whole trial period, participants of the MODUM field trials have access to their online Participant Dashboard. At their personal Participant Dashboard users can learn more about the project, refer to a user guide, and review the personal progress in the MODUM field trial.

Step 3: Ensuring commitment of the participants

The success of the field trials is strongly depending on the trial participants’ behaviour:

  • First, it is essential that the participants complete a sufficient number of trips using the MODUM application
  • Second, it is essential that the participants report back to the project and provide their assessments, comments, and insight into their experience.

In order to encourage participants to complete the minimum number of journeys using the MODUM application, progress wheels are placed prominently on both the app and dashboard.

In order to ensure that the project receives the necessary feedback from the trial participants, after the trial period users are sent a 10-response questionnaire to complete before they can receive their reward for participation.


MODUM addresses the environmental footprint in the transport sector by developing a new approach for pro-active demand-responsive management of traffic. This approach enables energy-efficient multi-modal transport choices accommodating dynamic variations, minimising the environmental impact and improving the quality of life in urban environments.
