Smart Trek: Busview
Busview implements a JAVA applet to display real-time transit vehicle locations on a variety of computing and operating system platforms. At this point, the applet displays Metro coach locations in King County, Washington.
Below is an image of the Busview frame. If this frame does not appear when the applet is launched, check the System Requirements below.
Busview requires both a browser and a Java virtual machine. Busview works properly with either the Sun or Microsoft VM. However, Microsoft will be discontinuing support for their VM, starting Jan. 2004. For this reason, we recommend using the Sun Java Plug-in (currently version 1.4.2).
NOTE: There are issues with Busview not working properly with the Sun Java plug-in ver sion 1.3. The symptom is that the applet will seem to start, the map will be displayed, but no data will be received. If this occurs, try upgrading the Java plug-in (to 1.4.x).
Macintosh:We do not have newer Macs available, and so we are not able to test Busview on current versions of the Mac OS. However, users have reported that Busview works fine under OSX 10.3.5, with Java 1.4.2, using Safari 1.2 or Mozilla 1.7.
(User reports are welcome--send to email@example.com)
The following notes pertain to older Macs and browsers on which we have tested Busview.
Busview DOES work on the Mac with Internet Explorer 4.5 but only if you use the Apple 'Mac Runtime for Java' (MRJ) version 2.1 and NOT the Microsoft Java virtual machine that used to ship with IE. (MRJ2.1 requires a PowerPC with 32 MB of RAM and Mac OS 7.6.1 or later.)
Busview does NOT work with any current versions of Netscape Communicator/Navigator (through 4.6/4.08). Netscape does not support the necessary version of Java. A future release of Netscape is expected to include support for the Apple 'Mac Runtime for Java'. This should make it possible to run Busview under Netscape on the Mac.
Latest VersionThe latest version of Busview is labelled 07-12-2004. To check the version number of your downloaded Busview applet, start Busview and select Help|About Busview from the main window to read the version number. For details on the new features included in this version and a complete history of Busview releases, please see the Busview History page.
