Ditto. I'm thinking we can point in the right direction but no one will write code unless they get a credit card number.

As for NS and EW, if you're traveling on a road and come to a light controlled intersection more than likely the oncoming traffic has the same color of lights displayed to them. You didn't say you had to control left turn lanes so I'm assuming you only have to control the major travel lanes. Only an insurance agent would want perpendicular paths to be the same. You also said you didn't have to build any circuitry so just recognizing that the N and S would be the same as well as E and W would be the same will save you some time in programming.

The whole rate thing for car measurement kinda throws me off. Usually you monitor how many cars are stacked up and adjust accordingly. If you did the car/minute you'd have to turn the sensors off during the stopped periods and turn them on at some point to measure traffic flow rates. You'd also have to take into account traffic legal speed during the sensed periods.

Jumper is correct in that you really need to get each LED blinking or at least turning on and off when you think they should. This ensures you can control them and that you've connected the PIC correctly.

Next step would be to post some code and/or schematic and you'll be overjoyed at the response. Though, as you're claiming to be an ME student, I'm surprised you haven't asked for a schematic.

Anyway, just my thoughts.
