Abstract

The present invention is designed to complement the existing transportation infrastructure in order to alleviate ever-worsening traffic congestion in problematic areas by minimizing the impact of driver “bunching” habits and/or external events that lead to congestion problems. Events alleviated by the present invention may happen at naturally occurring roadway infrastructures such as merges, lane shifts, and exits, and under conditions like rush hour, accidents, stand-stills, and HOV lane activation times. Further, vehicles allowing their speed and spacing to be controlled should have access to high-flow lanes. This invention will best and most safely be implemented at low speeds when congestion is most problematic and bunching habits prevent the dissipation of gridlock. In particular embodiments, the invention will regulate multiple vehicle accelerations (non-negative acceleration) once a low threshold speed has been reached through the transmission of signals to receivers in properly equipped vehicles. The exclusive non-negative acceleration control system simplifies the manufacturing, safety and redundancy necessary for implementing such a system and is commercially viable.

Claims

1. An acceleration control system for a vehicle including:

a receiver configured to accept electromagnetic signals;

an activation module coupled with said receiver, wherein said activation module generates a signal if said receiver detects activation signals;

an accelerator control unit coupled with said activation module and the acceleration system of said vehicle;

wherein said activation module includes a signal from a velocity input signal line, said signal indicating that the velocity of said vehicle has reached a low threshold, said activation module incapable of activating said accelerator control unit unless said velocity of said vehicle has reached a low threshold,

wherein said vehicle cannot accelerate beyond a threshold velocity, when a positive acceleration limitation signal is transmitted.

3. The module for acceleration control in a vehicle as recited in claim 1, wherein said low threshold is zero.

4. The module for acceleration control in a vehicle as recited in claim 3, wherein said threshold velocity is determined by the velocity of a second vehicle in front of said acceleration controlled vehicle.

2. An activation module for acceleration control in a vehicle, wherein said module includes an input from a receiver and an input from a velocity signal line, said activation module coupled to a power source and a power output, said activation module sending power though said power output if said input from a receiver and said input from said velocity signal line are present,

said activation module becoming active when a low threshold velocity is detected and said input dependent on the velocity of a vehicle located in front of said vehicle.
