TOAST - Tactical optimization strategies to adapt urban transportation networks
Overview
Background & policy context:
According to the Global Health Observatory (GHO), more than half of the total population lived in urban areas in 2010. This proportion is expected to reach 60% by 2030 and 70% by 2050. The increasing concentration of population and the unplanned extension of urban areas raise several challenges, among which the management of the urban network infrastructures.
The TOAST project (Tactical OptimizAtion Strategies to adapt urban Transportation networks) aims at investigating a new set of emerging tactical optimization problem. It consists in setting directions on each street to improve the global transport system. This research has been funded in 2013 by the DRRT (Délégation Régionale à la Recherche et à la Technologie, Champagne-Ardennes region, France).
Objectives:
TOAST is an incentive project dedicated to analysing and improving an urban transport network by means of optimization. Thus, new configurations of the network can provide an alternative ground to reduce traffic jams.
It investigates tactical optimization problems of setting direction in urban networks to minimize travel distance as well as global congestion. Using the very same approach, it also provides solutions which act as deterrent policy, for instance in tourist areas.
