Hello Joby K Paul
I am making an initial enquiry to see whether you have the skill set and are interested in a project we are looking to start shortly. I am not a technical person so will not go into full technical details here.
We work in the public transport sector in the UK. We currently offer electronic signage for bus stops, but we are looking to develop an on-bus AVL unit that will take an RS485 feed from a bus ticket machine and GPS date, and communicate this via GPRS to a central server that will calculate position and create a prediction of when the vehicle will arrive at a bus stop.
There are possible extensions to the key functionality, these being on-bus wifi and push to talk communication via the GSM network, and lastly CANBUS integration.
If this project sounds like it might be interesting to you, perhaps you can let me know. At that point I will hand over to my engineers to scope out the project with you.
Hope to hear from you soon,
