These are the show notes for episode 22 of the Travels in a Mathematical World podcast. 22 is the smallest multidigit number such that the sum of its digits equals the product of its digits. More about 22 from Number Gossip.
Recently I visited Scotland and while there I met Mike Maher, Professor of the Mathematical Analysis of Transport Systems at the Institute for Transport Studies, Leeds University. Mike sat down with me at the University of Edinburgh and talked about his work in transport modelling.
You can find details of the research carried out in the Network Modelling group at ITS, Leeds, a brochure for the SATURN traffic assignment software suite and further details about microscopic traffic simulation modelling and the DRACULA program (including a downloadable software demo).
If you are interested in the topic, there was another episode of the podcast on transport optimisation problems, episode 3 with Joanna Hartley.
