Tutorial – Using TRAC-IT for aTravel Behavior Survey

Sanyo Pro 200 with Java Micro Edition (Java ME)


Trac it mobile application 1

TRAC-IT Mobile Application (1)

  • On the Sanyo Pro 200 (shown here), the TRAC-IT application is here:

    • “Main Menu->My Content->Applications->TRACIT”

  • You can add TRACIT to your Favorites List (accessible from main screen) through these steps:

    • “Main Menu->Favorites (left soft key)”

    • Select unused Favorite

    • Browse to “My Content->Applications”

    • Select “TRACIT” and click “Assign (left soft key)”

  • Now the TRACIT application should be available each

  • time you press the “Favorites (left soft key)” from

  • the main phone screen.

  • TRAC-IT will automatically start whenever the phone

  • is powered on, and will continue to run in the

  • background


Trac it mobile application 2

TRAC-IT Mobile Application (2)

  • The application should now be starting up

  • If it is the first time the application has been run on the phone, you’ll be prompted to allow the application to access information from your cell phone.

  • Select “Always Allow” for all prompts (including any future prompts) so that you will not be prompted in the future.


Trac it mobile application 3

TRAC-IT Mobile Application (3)

  • If you haven’t yet logged into the application, you’ll be prompted with a login screen.

  • Login using your username (most likely your email address)

    • You can type symbols (e.g. @, .) using the “*” key.

  • Enter your password as well (which is case sensitive).


Trac it mobile application 4

TRAC-IT Mobile Application (4)

  • If you logged in correctly, you should now see the TRAC-IT main menu screen

  • Once you’ve logged in, the phone saves your username and password

  • The application is designed to always be on, so you don’t need to exit the app or log out.

  • If you need to give the phone to someone else for tracking, select “(2) Change Users”, which will log out the current user


Trac it mobile application 41

TRAC-IT Mobile Application (4)

  • TRAC-IT has two modes:

    • Passive Tracking

    • Active Tracking (includes input from user)

  • To use the passive tracking mode, you don’t need to do anything else.

    • TRAC-IT is sending data to the server as long as the TRAC-IT Mobile application is running.

    • Just shut the phone and go about your business as normal

  • To use the active mode, you need to click “Record Trip” every time you start a trip, then enter more info

    • See the next few slides


Active trac it using the record trip function

Active TRAC-IT: Using the Record Trip Function

  • To Record a Trip and enter purpose/mode/occupancy information, select “(1) Record Trip” on the Main window and click “OK”


Current location

Current Location

  • The next screen asks for your current location.

  • At this screen, you can select a previously added location(E.G. Work), or you can add a new location with a location name.


Recording trip data

Recording Trip Data

  • Once you get to this screen, you are now recording GPS points

  • You can close the phone, and go about your trip

  • When you reach your destination, you need to press “End Trip”.


Finishing the trip 1

Finishing the Trip 1

  • One “End Trip” is selected, the “Current Location” screen will appear again.

    • Enter your end location

  • You’ll then need to choose a trip purpose:

  • And a mode of transportation:


Finishing the trip 2

Finishing the Trip 2

  • Finally, you’ll enter your household and non-household occupancy (if you were in a personal motor vehicle), and if you were the driver or a passenger


Quickstops

QuickStops

  • As a convenience to the user, we also include a “QuickStop” feature (instead of “End Trip”)

  • A “QuickStop” is just like ending a trip, but it assumes that you’ll be starting another trip right away from the same location

    • E.g., fill up on gas, dropping off person

  • So, you will enter the same info as

    if you had ended the trip, but will

    then click “Resume Trip” instead of

    entering your starting location again

  • You don’t need to use this feature (it doesn’t

    change how the data is collected) but feel

    free if you find it useful


Tutorial using trac it for a travel behavior survey

Session Email

After recording GPS data using the cell phone and TRAC-IT software, you will get your TRAC-IT Session email with your travel behavior. This usually happens the day after you record your data. If you don’t receive an email 48 hours after recording the data, please email Sean with your session ID for the data at [email protected]

Trip Email

If you used the advanced “Record Trip” feature, after recording GPS data you will get your TRAC-IT Trip email with your travel behavior, including the location description as the “Starting/Ending Location.” This usually happens the day after you record your data. If you don’t receive an email 48 hours after recording the data, please email Sean for the data at [email protected]


Uploading gps data to openstreetmap

Uploading GPS data to OpenStreetMap

Click on the “File for OpenStreetMap” link. You will be prompted to name the file something relevant and to save it in the GPX file format.

NOTE: Your SessionID appears in the name of the attached .ics file. You can use this name as the name of your GPX file. Just be sure to save the GPX file with the GPX extension (.GPX).


Uploading gps data to openstreetmap1

Uploading GPS data to OpenStreetMap

Follow the instructions in OSM Intro slides, or look at OpenStreetMap.org (http://wiki.openstreetmap.org/wiki/Upload) for instructions uploading any GPX file.

You can also view your data in Google Earth by clicking on the “File for Google Earth” link in the feedback email to get the data in KMZ (i.e. zipped KML) format.

  • Detailed technical information follows


Trac it mobile application

TRAC-IT Mobile Application

  • If you want to see the current GPS information, at the main menu press the “Menu” right soft key again, then select “GPS Status”.


Trac it mobile application1

TRAC-IT Mobile Application

  • You should now see information about the real-time GPS readings:

If you scroll down ->


Trac it mobile application2

TRAC-IT Mobile Application

  • GPS Status field definitions:

    • “Loc. Mthd”: Location Method used to calculate this position.

      • Asst GPS = Assisted GPS

      • Auto GPS = Autonomous GPS

      • “CellID” or “8” = Cell-ID

      • “0 – Invalid” = No GPS or other location data available


Trac it mobile application3

TRAC-IT Mobile Application

  • GPS Status field definitions (cont):

    • “Hor. Acc”: Estimated Horizontal Accuracy Uncertainty

      • Radius in meters defining a circle surrounding the calculated position in which the true position lies at the 68% confidence level


Trac it mobile application4

TRAC-IT Mobile Application

  • GPS Status field definitions (cont):

  • “SM Int”: Interval between GPS fix attempts, in seconds

  • “Lat”: Latitude, in decimal degrees in WGS84 datum

  • “Long”: Longitude, in decimal degrees in WGS84 datum

  • “Alt”: Altitude, the mean height above the WGS84 reference ellipsoid, in meters

  • “Fx Time”: Date and time when the GPS fix was calculated, in the local time zone

  • “Speed (m/s)”: Speed when the GPS fix was calculated, in meters per second


Trac it mobile application5

TRAC-IT Mobile Application

  • GPS Status field definitions (Cont):

  • “SessionID”: Unique identifier for this “session” of GPS data logging.

  • “Heading”: Heading when the GPS fix was recorded, made good in degrees relative to true north, in range of 0-360. 0, 360 = north, 90 = East, 180 = South, 270 = West.


Trac it mobile application6

  • The SessionID identifies a grouping of GPS data, and is usually around 24 hours long

  • You can cross reference this session ID with your emails to see which email corresponds with the current session you’re seeing
