Traffic map prototype

It looks like I've finally sussed this Regex function in Yahoo Pipes in order to extract the geo coding in a URL to plot accident information from the Highways Agency.

I was basically playing around looking for a feed to process and realised that the info provided by the Highways Agency is coded in a format thus:

http://www.trafficengland.co.uk/map.aspx?isTrafficAlert=true&lat=53.0195...

The challenge was to extract the bits for longitude and latitude.

Now I've tried before and got nowhere. This time I managed it.

The code to do it for latitude is: .+lat=(.+)&.+ And the code for longitude is: .+lon=(.+) Simple!

(He says, waiting to be stumped by the next bit of code)

Here's my eventual map:
