The Persistent Challenge of Modeling Traffic FlowNovember 1, 2013
In a blog post about the 2013 Gene Golub SIAM Summer School, Nick Higham (lecturer on matrix functions) commented on some extracurricular aspects of the event, which was held in Shanghai. Particularly taken with "Chinese (motor) cyclists, who carry a wondrous variety of goods on their bikes and ride without any attention to the traffic signals but miraculously seem to avoid accidents," he illustrated the observation with several photographs, including the one shown here. An article on the summer school by three of the students can be found here.
Dana Mackenzie also takes traffic as a subject in this issue: "Heterogeneous traffic," he writes, "is a headache not only for traffic but also for traffic modelers"; see Smells Like a Traffic Jam.
