Traffic speed surveillance system

A traffic speed surveillance system comprising:

• a set of monitor transceivers located along a roadway and communicating with a central processor, and including at least some stationary transceivers sending radio signals indicative of speed limit in the location of the particular stationary transceiver;
• a vehicle transceiver mounted in a vehicle and including:
• a vehicle receiver for receiving said radio signals indicative of speed limit;
• means for entering driver identification and for entering vehicle identification;
• speedometer means for measuring the speed of said vehicle;
• comparator means for comparing the measured speed against the speed limit;
• a vehicle transmitter responsive to said comparator means for sending radio signals indicative of a given relation between said measured speed and said speed limit and indicative of said driver identification and said vehicle identification;
• said monitor transceivers including monitor receivers for receiving said radio signals from said vehicle transmitter for reporting the given speed relation, driver identification and vehicle identification to said central processor.

A traffic surveillance system comprising:

• (A) a vehicle transceiver mounted in a vehicle, comprising:
• (1) a velocity surveillance computer;
• (2) key detector means communicating with said vehicle surveillance computer and signaling the presence of an ignition key;
• (3) driver identification reader means communicating with said vehicle surveillance computer for reading authorized driver identification codes;
• (4) driver interface means communicating with said vehicle surveillance computer for communicating with the driver;
• (5) speedometer means measuring the speed of said vehicle and communicating with said vehicle surveillance computer;
• (6) programming plug means communicating with said vehicle surveillance computer for entering information including vehicle identification and permitting programming only by authorized personnel;
• (7) nonvolative memory means communicating with said vehicle surveillance computer for storing data, including speed limit violations and driver identification;
• (8) receiver means communicating with said vehicle surveillance computer for receiving broadcast radio signals indicating speed limit;
• (9) transmitter means communicating with said vehicle surveillance computer for sending radio signals indicative of driver identification, vehicle identification, and speed limit violation;
• (10) a tamper computer communicating with said vehicle surveillance computer and removable as a self-contained unit;
• (11) second nonvolatile memory means communicating with said tamper computer for storing tamper data;
• (12) run enable circuitry communicating with said tamper computer for enabling and disabling operation of said vehicle;
• and
• (B) set of monitor transceivers located along a roadway and communicating with a central processor, and including at least some stationary transceivers each comprising:
• (1) a monitor surveillance computer;
• (2) programming plug means communicating with said monitor surveillance computer for programing thereof;
• (3) nonvolatile memory means communicating with said monitor surveillance computer for storing data;
• (4) gating switch selection circutry for controlling communication of said monitor surveillance computer with said central processor and said vehicle transceiver;
• (5) monitor transmitter means for sending radio signals indicative of speed limit in the location of the monitor transceiver;
• and
• (6) monitor receiver means for receiving radio signals from said vehicle transceiver for reporting speed limit violations together with driver identification and vehicle identification to said central processor.
