Hi, we're a group of students at NTNU in Trondheim trying to set up a prototype of a bike- and pedestrian registration.
Our scope is to build a scalable solution that helps logging pedestrian and bike traffic to that eventually would lead to better city planning. We aim to set up a simple prototype demonstrating the concept and participation in for pedestrians and bikers will be voluntary.
So far we have considered RFID, BLE and WiFi as possible technologies for registration. We are interested in any kind of feedback how to set up this prototype as simple, cheap and robust as possible.
Possible approaches so far:
1. Mobile network triangulation and interpolation
One possible way to achieve our goal is to use position data mobile network operators, all position data will be anonymizes and only logged from designated pedestrian areas (e.g. pavements.)
Throughout a city there will be checkpoints logging traffic from bikers, that have a module based on BLE, RFiD, WiFi etc. These checkpoint position data will be interpolated with triangulated position data. Overlap, will mean a biker, no overlap will mean pedestrian. Participation for bikers are voluntary, we're not sure how to handle privacy issues regarding triangulation from mobile networks.
Making hardware is of course more fun, but couldn't you instead just use peoples cellphones to track them through an app that the volunteers install?
We're thinking to set up a bluetooth low energy network using and using iBeacon to transcieve information from mobile phones. This makes the system voluntary for partitipation and very energy efficient for the participators.
Is this solution applicable with Silicon Labs Technology?
Sounds like a good plan, although we currently do not have Bluetooth Low Energy products in Silicon Labs.
