Wireless traffic light controller
First Claim
1. A control arrangement for overriding automated control of a traffic light having a pre-existing mechanical connector for receiving a temporary controller so that overriding command signals may be manually entered, comprising:
- a control unit to be operated by a person charged with assuming control of the traffic light, said control unit comprising electrical circuitry disposed to generate control commands and to transmit said control commands remotely; and
a stationary signal transfer unit having electrically circuitry comprising a receiver disposed to receive said control signals from said control unit, wherein said circuitry comprises a hard wired connection disposed to transmit said control signals, said hard wired connection comprising a removable connector which is disposed to mechanically connect to the pre-existing mechanical connector of the traffic light.

Abstract
A one-person remote control system for overriding pre-established control sequences of a traffic light, which control system is compatible with plug-in communications connectors conventionally provided with traffic light controllers. The remote control system comprises a stationary signal transfer unit which has a signal receiver and a plug-in connector for communicating with the traffic light controller, and a mobile control unit disposed to receive manual commands from the person providing overriding control, and a transmitter for transmitting manual overriding command signals to the stationary signal transfer unit.
