We have been working with Johnstone TOA taxis to provide them with a taxi fare calculator. 

This new system which is now implemented gives their customers the chance to get an estimate of the cost of their taxi journey from one point to another.  This can be done by postcode, address or place (an airport for example, or city centre).

The page requests a start point and end point and calculates the route on a map, returning the directions from Google directions and then goes on to calculate the estimated price for the journey for both a saloon car and MPV taxi and the phone number to call to make the booking.

Give it a try for yourself at http://www.johnstonetoa.co.uk
