Q: Is it possible to increase the distance and implement it directly on the road?
A: Yes, with modification at user end, it is possible to increase the distance and implement it directly on the road.
Q: What is the role of microcontroller in this project?
A: The microcontroller is used to refer to the dynamic timing provided by crystal oscillation
Q: How does it automatically sense the traffic?
A: By IR sensor arrangement, the traffic can be automatically sensed.
Q: Which microcontroller is used in this project?
A: A 40 pin microcontroller from 8051 family is used in this project.
Q: What is the blue and white color device used for?
A: The blue and white color device is the preset, used as a variable resistor.
Q: Is this project for 4 way junction?
A: Please note these are student level projects to understand the technology only and not designed for exact use off the shelf. In any case the other two sides would have the same circuit extended and the program just duplicated for that section. It makes no sense to get a repeat work for the sake of having it..The features desired by real use can be done but cost would be high enough beyond the affordability of an average student expenditure point of view. Therefore we have taken only one section consisting of 2 sides.
Q: What is the formula for calculating smoothing capacitor value?
A: There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.
Q: Can we develop a traffic accident information system?
A: If a number of vehicles are standing on a road without moving for preset time duration an alarm will be triggered.
