Morning commute in a single-entry traffic corridor with no late arrivals
چکیده انگلیسی

This paper analyzes a model of early morning traffic congestion, that is a special case of the model considered in Newell (1988). A fixed number of identical vehicles travel along a single-lane road of constant width from a common origin to a common destination, with LWR flow congestion and Greenshields’ Relation. Vehicles have a common work start time, late arrivals are not permitted, and trip cost is linear in travel time and time early. The paper explores traffic dynamics for the social optimum, in which total trip cost is minimized, and for the user optimum, in which no vehicle’s trip cost can be reduced by altering its departure time. Closed-form solutions for the social optimum and quasi-analytic solutions for the user optimum are presented, along with numerical examples, and it is shown that this model includes the bottleneck model (with no late arrivals) as a limit case where the length of the road shrinks to zero.


► Characteristic curve analysis for an LWR model of a single-entry, morning commute.
► Complete, analytic solutions for the social optimum under Greenshields’ Relation.
► Quasi-analytic solutions for the user optimum under Greenshields’ Relation.
► Economic properties of the time-varying toll that decentralizes the social optimum.
