The STS system is based on the following assumptions:
• Equipped vehicles have windshield-installed cameras,
connected to an on-board computer that is able to
compress video, recognize traffic signs and support the
inter-vehicle communication protocols;
• Equipped vehicles have GPS;
• Equipped vehicles have DSRC radios;
• Equipped vision-obstructing/long vehicles display a rear
sign mentioning ”STS Enabled” (a VANET enhancement
over the typical ”Long Vehicle” sign);
• Equipped overtaking vehicles have a screen on the
dashboard where the video streaming can be visualized.
