Abstract :
[en] With 2586km2, Luxembourg is the 7th European smallest country in Europe. Despite its small size this
country is facing important mobility challenges. Out of the 380 000 available jobs in the country, nearly
43% of them are occupied by cross borders workers. These 165 000 cross borders traveling every day
from France, Belgium and Germany generate an important pressure on the transport infrastructures.
Because 89% of the cross-borders workers and 74% of the resident workers commute by car, the road
system, at peak hours, reaches saturation.
In order to decrease the pressure (in term of commuting flow, residential prices, etc.) on Luxembourg City and to reach a more balanced polycentric development across the country the development of Belval has been decided by the government. This new-town which is located 20km south-west of
Luxembourg-City will attract economic activity and residential units. The University of Luxembourg will
be one of institutions relocating most of its infrastructure in Belval. Without any doubts, this workplace
relocation will greatly affect the University staff commuting mobility.
In accordance to any public institution or large enterprise in this country, the University is more and
more committed to reduce the carbon footprint related to the staff and students commuting behavior.
The MODU (national sustainable mobility strategy) defines strong modal split objectives and the number
of parking spaces available for the university on Belval site will rely on this national objective.
So far, few scientific contributions analyzed the accessibility variation for car and Public Transport (PT)
on important worker’s’ population considering relocation actions of this size. GIS tools and visualization
techniques will permit to quantify the car and public transport accessibility vari ation due to the
University move to Belval.
The scientific contribution of this article lies in the relation between the car & PT accessibility and the
development of Travel Demand Management (TDM) measures. Indeed, an innovative Parking
Management Scheme (PMS) integrating car & PT accessibility to the new campus as well as carpooling
use among the staff members will be presented. Our aim is to develop a mobility credit scheme system
where users could use points to park their car or use the public transport system. Soft modes might
collect additional points that could serve to get gifts or even cash back. Indeed, the objective is to reach
a pragmatic parking policy that lead Single Occupancy Vehicle (SOV) to shift, first, to soft modes, then, to
public transport and finally to carpooling. The key is the relation between the different travel modes and
their existing incentives or disincentives. This approach might help other major private or public
institutions to define optimum subsidy strategies regarding their parking and staff’s public seasonal
ticket costs.
