Detection and identification of vehicles with excess particulates in exhaust gases
First Claim
1. A method for identifying a moving vehicle continuously exceeding a predetermined level of particulate emissions, said method including the steps of:
- detecting the rate of change of particulate emissions in the atmosphere immediately above said vehicle at a first detection station;
detecting the rate of change of particulate emissions in the atmosphere immediately above said vehicle at a second detection station downstream station;
recording information identifying said vehicle if the rate of change of detected emission of said vehicle at either station exceeds said predetermined level; and
examining said recorded information from both stations and identifying said vehicle if its identity appears in said recorded information for both station;
and observing video information to determine whether a continuous particulate emission has occurred.

Abstract
A method and system for identifying, visually tracking and recording a moving vehicle exceeding a predetermined level of particulate emissions, the method including the steps of: detecting the particulate emissions of the vehicle at a first detection station; detecting the particulate emissions of the vehicle at a second detection station downstream of the first station; recording information identifying the vehicle if the detected emission of the vehicle at either station exceeds the predetermined level; and comparing the recorded information from both stations and identifying the vehicle if its identity appears in the recorded information for both stations and providing video tracking of the identified vehicle for an extended time period.

11. An apparatus for identifying a moving vehicle exceeding a predetermined level of particulate emissions, said apparatus including:
-
first detection means for detecting the rate of change of particulate emissions in the atmosphere immediately above said vehicle at a first detection station; second detection means for detecting the rate of change of particulate emissions in the atmosphere immediately above said vehicle at a second detection station downstream of said first station; recording means for recording information identifying said vehicle if the detected emission in the atmosphere immediately above said vehicle at either station exceeds said predetermined level and further visually recording the particulate emissions of said vehicle over an extended time period; comparison means for comparing said recorded information from both stations; and image recognition means for identifying said vehicle if its identity appears in said recorded information for both stations.

12. A system for identifying a vehicle emitting a high level of particulate emissions, the system comprising:
-
a first particulate detection system for detecting the rate of change of particulate emission from a vehicle in the atmosphere immediately above the vehicle as it transits a first transit point; a image triggering means located at a second transit point; a first imaging means interconnected to said triggering means for imaging vehicles and further visually recording the particulate emissions of said vehicle over an extended time period as they transit said second transit point; a processing means interconnected to said first particulate detection means and said first imaging means for locating identification parameters associated with the imaged vehicles when said first particulate detection system detects an emission exceeding a predetermined level. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
