Study traffic and parking around new urban projects

Eager to develop its urban core, the city of Yerres asked Technologies Nouvelles to carry out a study to measure the impact and needs induced by its three new real estate projects.

Faced with the challenges of development on increasingly constrained urban sites, Technologies Nouvelles provides its engineering expertise to its clients wishing to develop new urban development projects.

Prior to each project, it is important to carry out a feasibility study to anticipate the possible impacts on traffic conditions, by studying the most unfavourable configurations such as peak traffic periods.


In the city of Yerres, there are 3 real estate projects:

  • A real estate project in the heart of the city on the “YOYO” parcel, redeveloping a building along the rue Charles-de-Gaulle:
    • A first floor composed of 4 shops
    • About thirty housing units
  • A project to build an 80-unit apartment building on the “Calmette” plot, with a mixed programme: housing and a senior medicalised residence.
  • The rehabilitation of the Château de Budé to create 12 housing units in the city centre area.


To measure the impact of these new projects and anticipate changes in the traffic generated by their development, Technologies Nouvelles conducted a three-phase study:

Phase 1: diagnosis of traffic conditions

  • Traffic supply – urban diagnosis
    • General traffic
    • Public transport
  • Traffic demand – Traffic
    • Summary of Morning Peak Hours
    • Summary of Evening Peak Hours
    • Operation of intersections
  • Parking survey
    • Parking supply
    • Parking occupancy
    • Typology of uses

Phase 2: Integration of real estate and infrastructure projects

  • Traffic generation
  • Parking analysis

Phase 3: Development of recommendations

  • Several scenarios for making a street one-way


The expertise of our teams allowed us to provide concrete answers on the impact of future developments in downtown Yerres with recommendations and complete solutions.

Thus the teams have:

  • Characterised the parking supply around future developments,
  • Proposed several scenarios, including the creation of additional parking spaces or the sharing of uses on the perimeters where parking was becoming strained due to new projects,
  • Measured the impacts on traffic.
