Upstream studies
The objective of the upstream studies is the emergence of a shared vision on necessary development of transport infrastructures to respond effectively to travel requirements. As a vital decision-making assistance tool, they respond to the following issues:
- Evaluation of the relevance of the objectives sought: reduce journey times, serve new territories, improve safety, increase capacity, etc.
- The identification of the possible solutions: modify and optimize the use of existing infrastructures, create new infrastructures, etc.
- The technical, environmental and economic feasibility study of the different solutions,
- Explanation of the possible phases and comparing of the different solutions.
This is therefore a listening, analysis and advice mission: evaluate the opportunity of the project, define it, draft several scenarios, characterize the feasibility of these scenarios and compare them.
The upstream studies therefore seek to enlighten choices and create the basis for the economic, environmental and technical legitimacy of the infrastructure projects. They involve transport economy, territorial development and environmental analyses in all technical domains relating to transport infrastructures. These studies are piloted by high level engineers who have developed a culture in these different domains.
In addition INEXIA Menighetti Programmation, a subsidiary of INEXIA, completes this offer by proposing upstream study skills in urban and architectural programming.
"The upstream studies enable us, for example, to add value to a rail infrastructure project by improving regularity. On the Paris/Mantes-la-Jolie via La Défense line, the study carried out by INEXIA showed that one of the most sensitive points was in the morning at Mantes la Jolie station with the insertion of trains towards Paris into the flow of fast trains from Normandy. This enabled us to quantify the gains that would be made by separating these flows. Result: 2 regularity points gained, with 64,000 passengers concerned per year. » Cedric Kervella, Upstream Project and Expertise Director.
