Effective vehicle toll operation can be greatly enhanced by efficient monitoring mechanism. This can be achieved through the deployment of an automated monitoring system at every vehicle toll point. This paper presents a modality for implementing a microcontroller based monitoring system for effective vehicle toll operations. The system consists of Arduino Mega 2560 microcontroller unit, two units of ultrasonic sensors MA40E7R and a unit of SIM 800L GSM/GPRS Module. Each unit of the ultrasonic sensor, positioned at the toll point, transmits ultrasonic pulses into the air and detects the reflected waves from a vehicular object. When the two units have detected reflected waves simultaneously, a protocol car Found is implemented in the microcontroller unit. Each time this protocol is implemented, the counting sequence of the microcontroller is increased by a step. For each increment, a time stamp and count sequence is recorded in the microcontroller's memory slot; and a protocol send DataOnline is implemented through the SIM 800L GSM/GPRS module simultaneously. Arrangement was made using a dedicated cloud facility for real-time archiving and monitoring of data generated by the ground station while testing was going on. The system's operational cycle ensures complete elimination of human bias and guarantees minimal systemic error thereby ensuring effective monitoring operation.
