Introduction
TrafficWatch is a programs that can be used to help drivers with
traffic related information. This program is designedto be used with
QuickLaunch which ties this and other programs to the WayPoint
navigation software.
TrafficWatch is built in to all WayPoint units.
TrafficWatch is supported by a live database that collects
information and sends the data to the Pocket PC via the internet. It
can make use of a live mobile connection or it can collect data via
ActiveSync and then display the data when the connection is lost.
For example, a user could collect traffic data prior to leaving the
home or office and then reference the data for decisions while
traveling.
This program uses your GPS position as reported by WayPoint to
determine the area of coverage for the screen. In the absence of
current GPS data this program will use the last known position.
Subscription
TrafficWatch, along with Weather Underground, requires a
subscription and monthly fee to access the live data. One
subscription provides access to both programs. The WayPoint 200
includes a one year free subscription. WayPoint 100 users can add
this service for a small monthly fee.

TrafficWatch Overview
TrafficWatch uses an Internet connection to retrieve live traffic
information in the form of a road map display, text displays and
table displays as well as audio. Data shows the speed of traffic flow
and the location of traffic incidents for major freeways and some
surface streets. TrafficWatch can be used to identify potential
traffic bottlenecks in selected areas in real time or near real time.
Start TrafficWatch
To start TrafficWatch follow these steps:
1. Make sure you have an Internet connection. (See “Internet
Connection Problems” on page 17 if you are not sure.)
2. You should be running the WayPoint Navigation program or
have used it with a GPS connection in the past. The most
recent GPS position will be used to determine which traffic
map to display.
3. Start QuickLaunch and use the TrafficWatch icon to start
TrafficWatch. QuickLaunch can be started two different
ways.
5
•Tap Start > QuickLaunch. The screen shown in Figure 1
will appear. Tap the TrafficWatch icon.
Figure 1 QuickLaunch
•You can also use the WayPoint hotkey button from the
WayPoint navigation software as shown in Figure 2.
6
Press and hold the WayPoint button for about a second.
Figure 2 Starting QuickLaunch from WayPoint
This will also bring up the QuickLaunch program and the
TrafficWatch icon can be selected.
When the TrafficWatch icon is tapped the following sequence will
be seen:
1. An updater program will run that checks to see if you have
the latest version of TrafficWatch. If there is an updated
version you will be given an opportunity to download it.
2. Wait a few seconds for the splash screen and then the local
map to be downloaded.
3. The local traffic map will be shown based on your current or
last known GPS location.
If you tap the in the title bar, the program revert to background
operation and will continue to update maps as long as an Internet
connection is maintained. Use the exit command to actually exit the
program.
7
The running copy of TrafficWatch can be displayed using the
QuickLaunch thus WayPoint can be used to view TrafficWatch at
any time by calling up QuickLaunch.
It is also possible to use TrafficWatch without using QuickLaunch.
It can be started with Start > Programs > TrafficWatch. When
starting TrafficWatch in this way it is possible to switch between
WayPoint and TrafficWatch directly using the WayPoint hardware
button.
If the Internet connection is lost the time is recorded and if the data
becomes too old to be useful a warning will appear.
The GPS location is shown as a blue dot on the map screen. If you
are driving the blue dot will track your position and move on the
screen. The screen will attempt to follow your position but if you
travel too far the unit will need to obtain a new map. This will be
done automatically if you have a live Internet connection.
The data is updated automatically. A progress bar shows when
data is being updated.
To view the data tap the road icon from the lower right corner of the
today screen, start QuickLaunch again, or reselect the program.
The data will pop forward automatically if the Internet connection is
lost. The time is recorded and if the data becomes too old to be
useful a warning will appear.
Interpreting the Data
The traffic data is shown on a Map that indicates freeways and
some major surface streets for orientation. There are several forms
of data than may be shown on the map as illustrated in Figure 3.

•The small circles show

measuring points. These
indicate approximate speed
through the area.
Green full speed
Yellow some slow down
Red severe slow

open no data
Figure 3 Sacramento
•Yellow Triangles show incidents (often accidents or other
traffic stoppage) or congestion. These are usually reported by
the Highway Patrol (State Police). Thereare some examples of
these in figure 4 which shows San Jose.
•Red Triangles are even more severe traffic stoppage. These
usually mean one or more lanes are closed.
•Traffic Cameras are shown in some areas. These are live
cameras as seen on TV monitoring the traffic flow. They are
not used in TrafficWatch.
•Airport Locations are shown for reference.
•Highway Numbers are shown.
•The time on the display represents the time of the last sample.
The update interval is automatic and determined by the
frequency of update information.
•Error messages may be shown just above the time data.
Once an Internet connection is lost the data will get stale and will
no longer represent current conditions. The time since the last live

data (Internet connection) will be displayed and after 45 minutes
the display will be considered too old to be usable.
San Jose
San Jose represents a more complicated view of this data. As can
be seen in Figure 4 there is more traffic data than roads on the
map.
The map data only shows the major freeways anchored around
I-680 and I-280 with I-880 shown through the center although it is
not marked. It is connected to highway 17 at the bottom of the map
and extends northward.
The San Jose airport can barely be discerned if you know where to
look (hint: it is the nose of the plane just peeking out from under all
the traffic data). Highway 101 is shown and there are some state
highways as well. You can see State Road (SR) 237 clearly and
SR-85 is conspicuous by its absence of speed information.
Figure 4 San Jose
10
SR-84 is shown running between I-880 and US101 across the bay
waters to I-880, but the real road extends down to I-280 and up to I-
680 and beyond. The speed sensors show where the road goes
even though the map does not.
Locals can probably discern Lawrence Expy, San Tomas Expy,
Montague Expy, Tully Road, Capital Expy, Almaden Expy, Foothill
Expy, and Central Expy which all show speed data.
Using TrafficWatch
The ideal way to use TrafficWatch is with a live data connection all
of the time. If you use the program like this the map will change
automatically to show you information about the area you are near
so long as WayPoint is also running to provide the GPS input.
Another way to use this program is to collect data from home or
work and then grab the PDA unit as you leave. The data image will
be the latest one available and will likely still be able to provide you
with accurate information to use to make traffic decisions.
If you want more information about a particular incident you see on
the screen you can tap the incident and after a short delay a voice
will tell you about the incident if there is more information on it.
Sometimes there is no further information available. You can also
circle a group of incidents and the voice will tell you about all of
them.
For text of the incident data see the section titled Traffic Report on
page 12 for the Traffic Report.
