To improve traffic operations, develop new congestion mitigation strategies, and reduce negative traffic externalities, understanding the basic laws governing the network\u2019s critical number of vehicles and the network\u2019s traffic capacity is necessary.<\/p>\n<p><!--more--><\/p>\n<p>However, until now, a holistic understanding\u00a0of this critical point and an empirical quantification of its driving factors has been missing. Here\u00a0we show with billions of vehicle observations from more than 40 cities, how road and bus network topology explains around 90% of the empirically observed critical point variation, making it\u00a0therefore predictable. Importantly, we find a sublinear relationship between network size and critical accumulation emphasizing decreasing marginal returns of infrastructure investment. As transportation networks are the lifeline of our cities, our findings have profound implications on how to build and operate our cities more efficiently.<\/p>\n<p><a href=\"https:\/\/ethz.ch\/content\/main\/de\/news-und-veranstaltungen\/eth-news\/news\/2019\/11\/urbane-verkehrskapazitaet.html\" target=\"_blank\" rel=\"noopener noreferrer\">Artikel in den ETH News<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Traffic in an urban network becomes congested once there is a critical number of vehicles in the network.
