In this challenge you have a city map and a bunch of passengers to pick up and deliver with your computer controlled car fleet. You just have to work out the best way to deliver the 300 or so passengers without keeping them waiting too long and making the most money.
The image above is the city with gray bars being the roads.
That starts in December, meanwhile the deadline for challenge 64 is December 2nd so just over a week to get your entry in for that. I hope to have Linkage running tomorrow as well.
