Routing and Traffic Signal Preemption Engines

•Determine location of 911 calls for service.– Attempts to determine “exact” location

of call.– Defaults to Geocoding if “exact” location

not found.– Uses Map Page grid data for validation.

4665 Paramount PlGeocoding Example

Exact Location Geocoding Location

•Optimal route considerations.– Street segment

impendence data.– Turn penalties.– Call on left or right side

of street.– Time of day/day of

week.

Routing and Traffic Signal Preemption Engines

•Traffic signal preemption– Identifies traffic

signals to preempt along route.

– When possible limits green signal to fire vehicle’s path only

– Timing based on vehicle’s speed.
