We could conceive a sociology of urban motilities associated to the act of going to work as composed of:
1. a dromology of displacements. This includes the study of speeds of material and immaterial (informational) transfers, kinetic energy in relation to the type of propulsion or fuel (animal, mechanic, fossil, electric etc.) and the type of medium (earth, water, air, wires, aether); average and instantaneous speed of transport, coefficients of velocity (= speed + directional vector, thus considering movements of entrance, exit, turning, etc.), accelerations, decelerations, queues, jams, accidents, collisions, and their consequences; the study of transfer vectors, i.e. means of displacement (in relation to the different speeds each type of vehicle ensures, be it private, public, or hybrid transport) and the infrastructures for displacement (in relation to the different speeds they ensure, impose or invite); description of distances and travel durations, daily and weekly overall time spent on travelling et
