Russ posted about a Flash Lite application for Series 60 that displays recent images from New York City traffic cameras on your phone. Not to be outdone Christopher Schmidt had a quick play at writing a similar app in Nokia's Series 60 Python, the result is this Traffic Cam Proof Of Concept written in about 1 hour 20 minutes!
It's a nice app, but not being in New York it's of little use to me, fortunately the BBC's Travel News page has a load of traffic cams, so I grabbed the BBC's list of London traffic cams and hacked up a London variant of Chris's app. You can find my version here - http://feetup.org/code/py/traffic.lon.py.txt
In keeping with the RAD theme, I timed how long it took me to create, 30 minutes to find the url's of the cameras and put them into a text file, 20 minutes to hack these urls into the code, and I'd got a functional app. Now it's not that pretty; the location names are all in uppercase, and the image sizes from the BBC site (320x240 and around 40k bytes) mean that you need to wait around 10 seconds for the picture to load (at a cost of about 10p for the average UK GPRS user), and zoom in to get the best view, but as a proof of concept it's great.
Update: I've been pointed at Frixo an interesting site that seems to cover the UK's traffic with live updates every 3 minutes. No traffic cams that I can see yet, but lots of useful info (traffic, weather etc), with maps of jams etc. Good stuff, highly recommended.
