A Ramp Meter is a device that regulates the flow of traffic entering freeways according to the current traffic conditions and

they have been shown to decrease traffic congestion and improve safety.

A Ramp Meter is to be designed based upon a $20$ MHz C $167$ microcontroller and this is to be developed using the Keil IDE.

Operation

The total freeway capacity is $3400$ vehicles per hour

$,2$ induction loop vehicle detectors indicate passing vehicles on the $2$ lanes of the freeway

The vehicle detectors have a digital output that pulses high for $1$ s

At peak times, red and green signals should prevent or allow vehicles to enter the freeway respectively

A green signal should allow $1$ vehicle to enter the freeway

During off$-$peak times the yellow signal should flash at $1$ Hz

Off$-$peak times are when less than $10$ vehicles pass the freeway induction loop vehicle detectors in a $20$ s period

The red, yellow and green signals are turned on by a high logic level

An induction loop vehicle detector indicates a vehicle entering the freeway from the on$-$ramp

The red stop time should increase from a minimum of $3$ s to a maximum of $20$ s to reduce the rate of vehicles entering the

freeway in response to increased traffic already on the freeway
