Network design of moving walkways in transportation hubs

Transportation hubs, such as airports and train stations, tend to experience congestion as their recent diversication of services attracts more people and the demand for mobility keeps increasing, while the expansion possibilities of the infrastructure are limited. Moving walkways, whose use is widespread to deal with long walking distances, can be a key infrastructure to reduce conges- tion and travel time. We develop an optimization framework which explores the disposition of moving walkways in transportation hubs with respect to two contrasting objectives: minimizing both the total travel time and the total in- stallation (capital) cost. We dene ow-dependent walking speed functions to model congestion. Its in uence on the route choice made by the pedestrians is then included thanks to a user-equilibrium formulation. This methodology is applied to the future train station of Lausanne, Switzerland. Simulations yield positive results with respect to travel time savings and also reveal chal- lenging aspects linked to the intersection between pedestrian ows and moving walkways.
