Imagine that the authorities allocate driving credits to everyone in the UK to combat congestion. You would receive a budget containing a certain amount of miles that you can drive without paying an additional fee. If you decide you need to drive more miles than your budget allows, you need to buy additional credits. If you drive fewer miles than you have in your budget, you can sell unused credits and have the money in your account.
To date, there aren’t any examples, worldwide, where Tradable Driving Credits have been implemented in practice, and there are not plans to do so at the moment. However, we would like to investigate the possible effects of the measure using this research, to be able to answer questions about the future potential. The University of Leeds, together with its partners, is making a start with this research through a dedicated website.
The research consists of two parts:
Part 1: Travel diary
You are asked to record your car travel for a full week. We will ask you several questions about each car trip.
Part 2: Scenarios
You are presented with two scenarios. In these scenarios you will receive a fictitious budget with driving-miles credits that would be valid for the week to be recorded. You can see what you might have to pay in this situation, or what amount of money may be credited to your account if you don’t use all your driving credits budget. You can decide how you want to organise your use of the car under the scenario. You can change your trips (cancel, change destination, change travel mode, etc.). Any changes will be reflected in the amount you might have to pay extra or in the amount of money that is credited to your account.
If you decide you want to participate, you can create your own account. This account is linked with your email address. This email address will of course only be used in connection with this research.
After you have registered you can start the research immediately by logging in. First you will be presented with a short questionnaire. Then you can start recording your trips, starting from the day on which you record your first trip. You are free to choose the day you want to start recording your trips, but you should start within one week.
There are two parts to the research. When you have finished part 1 (i.e. after 7 days), your personal scenarios will be calculated. This may take a few days.
After your scenarios have been calculated, you will receive an invitation to start part 2 of the research by email. You will need to wait until the invitation arrives before you can start this second part.
In part two you will be presented with two scenarios. You can choose if you want to change your trips in response to the scenarios. At the end of part 2 you will be asked to fill out a short questionnaire. You can finish part 2 in one session.
Time investment and incentive
The complete research (part 1 en 2) may take 30-45 minutes of your time. 40 vouchers worth £50 will be distributed among the participants via a prize draw. These vouchers could be spend at Amazon, M&S and Boots. Winners will be informed by email before November 30, 2016.
If you change your mind about participating in the research after you have completed the survey, you can have your data removed from the database for up to 4 weeks from the date at which you completed the survey. All you would need to do is send an email to firstname.lastname@example.org
