| Title: Expressway Control System
Background of the invention:
Solo drivers on expressways during rush hours are the basic cause of congestion , pollution and exploding expressway construction costs. The best solution is to get these drivers into car-pools. The car-pool lane is expensive and has not been effective enough to solve the problem. Toll lanes have been suggested as one means to solve this problem and the technology for automatically accounting for traffic on toll lanes is well known but I have invented a better way to solve the problem.
Description of the Invention:
At every on-ramp to the expressway each car entering the expressway is required to make a 2-second stop at a station that has (advanced implementations may not require the stop) an electronic detection apparatus on both sides of the lane (actually advanced implementations may not require apparatuses on both sides). The electronic detector apparatus records the license plate number of the car (out-of-state cars would be probably allowed to drive the expressway free of charge to avoid an overburdened database). The driver toots his horn if he has at least one human passenger in the car with him. This data is recorded in a computer. The solo driver is assessed an expressway use tax whose value is determined such as to provide an effective disincentive for solo drivers to use the expressway during rush hours. Periodic billing to the car's owner is the means of collecting the tax.
In terms of the detection apparatus the key improvement of this invention is that part of the detection apparatus which unequivocally records a commitment on the part of the driver of the car that (s)he has at least one passenger (there would be the option for a rule change requiring more than one passenger but I use one for exemplary purposes). The reason for the proposal of detectors on both sides of the car is to make the audio detector assuredly unequivocal, that is to say the beam of the detector must be narrow enough so that only the horn from the car under scrutiny is detected. Other aspects of the detection apparatus design, such as requiring reading licenses at different heights, and other aspects of the design are well within the current state of the art. |
