Current Traffic Video Sequence

A prototype demo of the proposed traffic channel application was created and posted on the web. A survey form gathered information about preferred camera views. This demo is still being run and can still be accessed; however, the demo takes a few minutes to run, and, when completed, you will no longer be linked to this page but will be at the end of the demo survey form. Based on the results of this survey, the following sequence of traffic videos is being sampled:

State Route 520 Midspan
Downtown - Yessler Way
Interstate 90 Midspan
Bellevue - NE 8th Street

The sequence, which runs for 30 seconds, starts at the top of a minute or 30 seconds past the top of a minute in universal time. Each scene is selected for 7500 msec.

The camera selection mechanism for the scenes is built into the \TrafficChannel\VideoController\switcher.cpp program.

// The individual commands to switch the cameras
char *sequenceCmds[NCmds] = {
	"114#a",		// cctv509 520 midspan
	"22#a",			// cctv105 Yesler way
	"49#a",			// cctv859 I90 midspan
	"150#a"};		// cctv693 Bellevue NE

The mapping of camera names to switch port numbers can be obtained from the WSDOT CCTV database on the traffic control machine, harley.
