Since the invention of mechanised transport, people have been able to travel ever greater distances in ever decreasing times. The potential for long distance travel has greatly increased the intensity of transport use in modern times, to the extent that it is no longer unusual to travel far further than we are naturally capable every day.
The potential for travel lies at the core of the modern city, connecting people to facilitate ever increasing economic intensity. Faster and stronger means of transport have allowed communities to grow and develop at increasing rates. The development of society is closely linked to transport capabilities: The modern city relies on mobility.
In the past, distance and travel time were directly proportional: as distance increased, travel time increased. But distance is no longer the principle factor in determining travel time. Rather intensity of use is the determining
factor - be it social, political, economic or industrial intensity. The more intense an area is, the better it is connected by
Mobility is the science of networks. The city is both a node in a greater network and itself a complex contained system of networks. This book is a study of networks, the means by which we connect and communicate. The intention is to explore networks universally, but as a point of reference, the city of Leeds will be used as a case study.
