Modelling and data collection

Quantifying the effects of a policy or project is crucial when it comes to making decisions regarding its implementation. TRANSITEC uses state of the art methods, tools, and skills to model projected situations.

Modelling is not limited to quantifying and distributing multimodal flows. Our experts also use a socio-economic and environmental approach in the simulations that they realize.

Static modelling

Macroscopic modelling (of a roadway and/or public transport network) is an invaluable decision-making tool, particularly in large, highly complex urban agglomerations. At TRANSITEC we prefer the controlled use of mobility models, thus:

maintaining a critical distance when interpreting modelling results
using them to reinforce our complementary analysis.

Our team is skilled in using, adapting and assembling multi-modal mobility models (VISUM in particular). As we are independent from any software supplier, TRANSITEC can advise on the best use of tools and the most appropriate static modelling method.

Dynamic modelling

Dynamic microsimulation or modelling permits an in-depth analysis of roadway network functioning, especially in complex situations involving a series of intersections, inter-modal interactions, signalised crossings, etc.

While TRANSITEC does use dynamic modelling (usually VISSIM), we rely on our own critical and nuanced analysis of the results. Entirely independent from any software supplier, TRANSITEC can advise on:

the best way in which to use a modelling tool
the most appropriate dynamic modelling method.

Socio-economic impact assessments

Ultimately, the aim of transport interventions is to improve the lives of those who rely on access and mobility, without harming the urban or natural environment.

Before any transport project gets the ‘go-ahead’, its advantages and disadvantages, or positive and negative impacts, must therefore be identified and measured.

TRANSITEC is able to demonstrate the socio-economic impact of a transport project through:

written reports supported by graphics and visualisations
standardised methods of analysis
specific tools developed by the company.

Environmental impact assessments

Globally, almost 25% of carbon emissions are attributed to the transport sector. This has a direct impact on the climate. At local level, traffic-related noise affects as much as 30% of the population, and is a determining factor in siting travel routes.

TRANSITEC has developed methods that take environmental impacts into account during all planning phases, from preliminary studies to project implementation. TRANSITEC is thus able to identify the best solutions for reducing carbon emissions and provide a concrete estimation of effect.

At the same time, we are involved with assisting emerging economies make low-carbon transport decisions as they build new transport infrastructure and search for mobility solutions – particularly we have guided authorities in their pursuit of Nationally Appropriate Mitigation Actions (NAMAs).

Surveys

Without data there can be no evidence-based decision making, which is why an organisation’s choice of survey design and method, and data collection tools, is no small matter.

We work with partners and use open-source software to collect and process data, particularly for traffic counts. TRANSITEC also uses automatic meters and cameras, which can be installed in study sites. This knowledge of survey methods and tools is an important asset when identifying the best way in which to answer the key research questions of a study.
