Try the ProbeView Java
application that shows real-time speed as tranist vehicles pass over the
virtual sensor locations. This requires
Web Start, distributed in Windows XP by default, to create a display map on your screen.
The red dots are the virtual sensors, and the yellow and
white circles connected to them show the speeds at the virtual
sensors. The yellow circles represent virtual sensors on
freeways and arterials, whereas the white circles represent
those on reversible freeway lanes. Holding your mouse over
any of the red sensor spots will show you the virtual sensor
number and location. Touching a roadway will show its name.
is a Java application that displays
a set of virtual speed sensors that update every 20 seconds, and color-codes the sensors to indicate the level of congestion.
This set of virtual detectors is being tested to be included in the Traffic Management System operated by WSDOT in Seattle
An alternative pictographic traffic map
that is created using virtual sensors that use transit vehicles as traffic probes is also available.
Speed estimates for buses traveling on freeways and arterials
are displayed on maps at the bottom of this page. Clicking on any of the shaded
areas will bring up a larger image of that area. From there,
moving the mouse over either any of the red sensor spots
or yellow bus circles will show you the exact location of
that particular sensor. The number in the yellow circle
represents the estimated speed of a bus.
Some of the red spots and yellow circles are clickable
and will show a static example of the type of plots that
will eventually be available for each sensor location.
New features have been added to the probes project. Estimated Travel Times for major corridors are
