Vectormart: Transport Consolidation
This is the third version of an experimental system designed to fill vehicles. It uses Perl, MySql and the Googlemaps API. It's a little broken as of 11/2009, I'm working on a new version and experimenting with Openlayers, to free it (somewhat) from the benevolent (so far) tyranny of Google.
It's now called vectormart, because I'm extending it to goods sharing as well as passenger sharing. It's more of an idea than a finished product, but the idea is transport optimisation and consolidation.
An untidy version of the software for downloading is here or below.
