Hey Bobby,
I suppose those ready made sensors are expensive because you'd need to measure loads of up a couple of tonnes!

If you can exempt that variable, you can try using proximity sensors or laser sensors to detect the presence of vehicles. Also, you don't need to dig up the road to install these sensors, unlike the pressure ones.
