I was recently quoted in an article on traffic signal synchronization – an ongoing project in Minneapolis right now. I have a contrary view to conventional wisdom on this topic as I have been quoted in the article and expressed in greater detail here.
Communities like traffic signal synchronization because it is smart technology that can reduce congestion and increase traffic flow without making any geometric changes to the roadway system. My argument is that these technologies work a little too well – they actually create induced demand which in the longer term leads to more congestion and air pollution and poor land use decisions. I’ll stand by my quote in the article in that traffic signal synchronization is a solution that becomes a victim of its own success.
