More than 10 binational transportation planning studies.
Over 12 national strategic highway transport and ITS plans.
More than 15 comprehensive mobility projects in medium and big cities all over the continent.
Over 10 continuous years acting as independent engineers in almost 5,000 km/lane/year
of roadwork.
Over 150 road impact studies and almost 80 parking lot projects.

Traffic and revenue
Investment-grade studies to determine vehicular volume and revenue levels associated with toll payments in a highway asset throughout a specific time interval.

Macro and micro economic planning studies for the identification of relevant projects for regional development.

Cost-benefit analysis
Social feasibility determination of infrastructure projects.

Intelligent Transport Systems – ITS
Research for the application of advanced technology arrangements related to infrastructure and transportation systems operation.

Urban mobility and Transit engineering

Comprehensive mobility studies
These studies include the multiple factors that comprise mobility (pedestrian, cyclist, vehicles, freight, public transport, etc.), and they identify and prioritize the necessary actions to improve it in determined urban areas and/or geographic regions.

Public transport system structuring
Initial approach and early evaluation of possible improvement options in public transportation systems.

Road impact studies
Identification of possible traffic alterations created by new urban road features and subsequent viable solutions proposal.

Microsimulations of the interaction between any transportation mode, over any type of communication mode and with any type of control, for the evaluation of operating conditions.

Parking lots
Design, master plans, and feasibility studies.

Transit engineering
Comprehensive analysis of urban mobility, considering the requirements and characteristics of user trips, physical infrastructure, transit control systems, and transportation modes available.
