Transport engineering

Track and alignment design and studies for railways, metros and highways.

• permanent-way geometry: horizontal and vertical alignment, cant, transition curves, clearances and turnouts;
• alignment review: minimum radii, transitions, gradients, clearances and compliance with standards and operating requirements;
• capacity and transport studies: demand, supply, headway and operation simulation;
• station areas: catchment, walking access, intermodal connections and corridor prioritisation;
• CAPEX and OPEX estimates to support investment decisions.

Typical requests: independent review of preliminary or detailed design; alignment alternatives for a critical section; technical support for proposals and tenders.

Coordination of complex projects

Technical coordination of projects with a public agency, a concessionaire, a consortium and designers from several disciplines.

• coordination of disciplines and multidisciplinary teams;
• interface with public stakeholders and with concession contract requirements;
• BIM modelling and design document control;
• technical support on claims, contract rebalancing and scope verification.

Typical requests: interim technical coordination for an engineering firm or concessionaire; a project in permitting or awaiting approval by the granting authority.

Data analysis

Processing, analysis and modelling of crash, traffic and transport operations data.

• integration and cleaning of public and private datasets: crashes, road network, counts, operations;
• spatial analysis: crash clusters, critical sections, catchment areas;
• statistical modelling: comparison between sections adjusted for exposure (safety performance functions, Empirical Bayes), time series, causal inference;
• evaluation of the effect of interventions and operational changes;
• interactive dashboards and technical reports.

Typical requests: crash diagnosis for a municipal network or a concession highway; evaluation of the effect of an intervention; quantitative input for mobility plans and for claims under concession contracts.
