Claim 10:
11. A dual mode method of assessing a toll fee at a toll point in a toll road system, said dual mode method comprising:
a) collecting electromagnetic loop sensor data of a vehicle as it travels on a lane through a toll point at a time and a date and determining a first axle count based on said sensor data;
b) collecting side angle video images of said vehicle as it travels through said toll point;
c) collecting overhead still camera images of said vehicle as it travels through said toll point;
d) collecting RFID identity data from said vehicle as it travels through said toll point if said vehicle has an RFID tag;
e) determining vehicle identity based on c or d or both e and d;
f) creating a transaction record in a computer system comprising copies or links to said sensor data, said video images, and said still camera images, said date, said time, identity of said lane, identity of said toll point, vehicle identity, and said first axle count;
g) analyzing said video images using computer vision and machine learning to determine a second axle count based on said video images;
h) comparing said first axle count and said second axle count;
i) repeating step g and h until said first axle count and said second axle count are identical; and
j) charging said vehicle a toll based on said identical axle count;
k) generating a monthly summary of charges to said vehicle and sending said monthly summary to an owner of said vehicle; and
l) wherein said dual mode method has an error rate of <0.05%.
