IMPS in No-Parking Enforcement IMPS is installed at the roadside to monitor the no-parking zone.  IMPS license plate reader automatically reads plates of vehicles in no-parking zone. IMPS No-Parking Enforcement software keeps a record ofvehicles in the no-parking zone.  Vehicles that remain in the zone longer than a grace period are detected and records retained for enforcement action.

IMPS in Access Control

• IMPS is installed at the entrance.
• IMPS license plate reader automatically reads plates of every vehicle entering.
• Alarm is raised for unauthorised vehicles.
• Images retained for enforcement.

IMPS in Expressway Shoulder Enforcement
Normally, only broken down vehicles are allowed on expressway shoulders. In Singapore however, many vehicles wait at the shoulders for the expiration of the Area Licensing Scheme when entry into downtown area is toll free.

• IMPS is installed at the roadside to monitor the road shoulder.
• IMPS license plate reader automatically reads plates of vehicles in road shoulders.
• Records of such vehicles are retained for enforcement action.

IMPS in Yellow Box Enforcement
Yellow boxes or jam-busters (as known to New Yorkers) are traffic junctions where through traffic must ensure that they pass completely through the junction when the lights turn red. Vehicles left in the junction area after the lights turn red are deemed to have committed an offence.

• IMPS is installed at these junctions to automatically read the vehicle plates.
• A synchronised digital CCTV system is also installed to capture the overall scene of vehicle and the traffic lights.

IMPS in Red Light Enforcement
Vehicles sometimes fail to stop at red.

• IMPS is installed at these junctions to automatically read the vehicle plates of errant vehicles.
• A synchronised digital CCTV system is also installed to capture the before and after scene.

IMPS in Bus Lane Enforcement
In Singapore, bus lanes are marked with thick yellow lines as the lane marker. During peak hours, only buses and other HOVs are allowed in the bus lanes.

• IMPS Bus Lane Enforcement System are installed randomly in buses.
• Sofware based Bus Lane Marking Detector (BLMD) determines if bus is travelling within a bus lane.
• Upon confirmation by BLMD that the bus is within a bus lane, IMPS license plate reader automatically reads plates of vehicles in front of the bus.
• Plates read are compared against a "white list" of authorised vehicles. Unauthorised vehicles images, plate numbers, date, time and bus route are recorded for enforcement action.

IMPS at Border Crossings

• Typically local authorities have no owner records of out of state or foreign vehicles. IMPS is installed at border crossings to automatically read the vehicle plates. Plates read are matched against a list of outstanding offenders. Alarms are set off when offenders are matched. Vehicles are stopped immediately for enforcement action.
• Plates read may also be matched against black list compiled by customs, immigration, police, etc.

IMPS Trip Timing System

• IMPS LPR systems are installed at two points of a stretch of road or expressway.
• By timing the vehicle between these two points, the average speed of the vehicle may be determined.
• As the system measures the average speed, vehicles will be encouraged to maintain speed limits for the entire stretch of the road.
• For radar type speed enforcement, vehicles tend to slow down before the enforcement point ( sometimes abruptly thereby causing accidents ) and then speeding off again afterwards.

IMPS Traffic Calming using Trip Timing System

• In rural towns close to major expressways or linking expressways, through traffic tends to over speed.
• By suitably locating trip time systems at major entry and exit points to the town, offenders may be detected and stopped for enforcement action.
• As average speed is used, vehicles will be encouraged to keep within speed limits for the entire duration in town.

IMPS in Electronic Toll Enforcement System

• IMPS is installed at toll points to automatically read any offending vehicle plates

Images may be used as evidence in enforcement action.

Toll Fraud Detection
One common trick is for drivers to swap toll tickets so that both drivers would appear to have taken shorter trips and pay less toll charges.
By using IMPS to read plates and encode on tickets, such practises can be easily detected.
