This collection of information is voluntary and will be used to help gain an understanding of the impacts of varying toll rates in response to congestion. Public reporting burden is estimated to average 30 minutes to 2 hours per response, including the time for reviewing instructions searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Please note that an agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control number for this collection is 2125-XXXX. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to: Information Collection Clearance Officer, Federal Highway Administration, 1200 New Jersey Avenue, SE, Washington, DC 20590.

Note: All the scripts and instructions are read or spoken to the participants while they can view the written script.

Field driving script

Now we will tell you what you will do during the next couple of weeks, until your next session. During this period you will have a GPS unit in your vehicle. It will be plugged into your cigarette lighter the entire time. As long as it stays plugged into the cigarette lighter there is nothing else you need to do. Just leave it there until you return.


The GPS unit will record all the roads you drive on and at what times you drive. This unit is not connected to any other devices in your vehicle. It does not transmit any signals so nobody can see where you are going while you drive. It is only recording, not sending any information.


When you return we will download this data to our computer. However, we are only interested in your driving on select routes. Thus as we download the data we will destroy any other driving information, except those routes. Therefore we will not save any information about the location of your home, your work place, or other places you visited.


The routes we are interested in are ________, and __________ We will save your driving records from some distance beyond these points. Just far enough so that we can identify in our records which way you came from when you entered these routes. But not so far that we can identify your home, work or school locations.


How will you get paid for your driving during this time?


First, you will only get paid when you drive during weekdays ______________ in a westbound direction, or ______________ in an eastbound direction, plus __________________ in either direction. Each week we will select your first 10 drives on these routes during these times and pay you for those. For example, if you drive every day during a standard (enter days) work week driving to ___________ in the morning and back in the evening you will be paid for your drives (enter days) morning and evening. You will then not be paid for any (day) driving since you already completed the 10 paid drives that week. If you only drive during four of the week days, but travel the route on (day) as well, you will be paid for the (day) drive because you only fulfilled 8 of the 10 paid drives during the week. However, if you are a commercial driver and you drive multiple times on the route each day. You may fill your quota of 10 drives much quicker. If so, we will not pay you for any more drives that week, but you will be paid again the following week for an additional 10 drives. (We will limit the number of valid drives you get paid for in any one day to ___.)


You will have to drive the entire distance from ___________ to __________ without stopping for any other reasons than traffic congestion. If you stop for other reasons it will not count as a drive we will pay for. So if, for example, you start on ___________________ but you get off at ____________, the drive does not count as one of your 10 drives. Similarly, if you were to pull over to a shopping area to do some shopping the drive would not count as one we pay for.





You will be paid $____ for each of these drives. The maximum number of drives you can get paid for is 20, so the most you can earn is $____.


In the weeks following your next session with us we will change how much you get paid. We will explain to you at that session exactly how the new payments will be determined. For now, however, you get $___ for each of the 20 drives.


When you return we will download your GPS data. We will remove all the driving records that are beyond our routes. Then we will calculate how many drives you did that we pay for. You will be paid that money at the second session.


At the end of the session we will go with you to your vehicle and help you find a good way to keep the GPS unit plugged in. If at any time you have questions about how you are getting paid or problems with your GPS unit just email us at [email protected] and we will get back with you as soon as possible.


If there are problems with your GPS unit, either because you had to unplug it or for other reasons, and it does not record your drives we cannot pay you for those drives. We will show you how you can see that it is getting power and operating properly.


It is therefore important that you let us know of any problems you are having as soon as possible so that we can help you correct them.


For your own safety, and for the safety of other drivers around you, you should not attempt to plug the GPS unit in or out while driving, and you should also refrain from looking at it to verify if it is working while driving. You can easily verify that it operates properly while parked.


About your GPS unit


This unit must be plugged into the cigarette lighter in the car to work.

If it comes loose while driving you should pull over to the nearest parking lot before plugging it back in.


While parked you can check that the red or green light is on, indicating that it has power.


Before driving off and after you have stopped you can check that this light is green rather than red, indicating that it is recording your position.


You should keep the unit in the glove compartment or attached to one of the vents. We will assist you in finding a good spot for it where it will work and not be a distraction while driving.




KEEP THIS IN YOUR CAR
