Rural Intersection Decision Support (IDS) System Demo Highlights

What you won’t see

(Well, probably not this)

What you will see

Animation of LIVE data collected by all IDS system sensors (projected on a screen in a tent)

LIVE demo of Xroads vehicle trajectory tracking (projected on a screen in the tent)

Radar sensor / processor & communication suite (monitoring mainline traffic)

Laser / radar vehicle classification sensor suite (minor road traffic)

Surveillance cameras (IR and visible light, Xroads and mainline)

Controller Cabinet / Wireless communication

Other Highlights

Wireless broadcast / reception capability Laptops/Tablet PC’s running animation software to

illustrate capability of intersection communicating to vehicles within range of intersection

Probe vehicle broadcasting engine speed, vehicle speed, and throttle position

Animation running on tablet PC near roadside for “eyeball” calibration/verification

Intersection Crossroads – Vehicle Classification

What you won’t see

RWIS at the intersection 0.9 miles northwest of intersection Will be pointed out on the bus

GOOD live Infrared camera video Quality issues in bright daylight conditions Tracking easier with visible light cameras Will likely have IR monitor at controller cabinet.
