Quetzal

Modelling transport demand.

Quetzal is an open-source solution offering a framework and algorithms for the development of your transport models.

Developed since 2016 by SYSTRA’s transport modelling experts, Quetzal brings an alternative to closed-source software. As an open-source Python library, it provides an answer to the downsides such software may cause: affordability, integrability and transparency.

We provide you with the services of a team of modellers-developers dedicated to the design of your models and the integration of your mobility data.

Types of model

Transit Assignment Models

Quick to develop and cost-efficient, they allow public transport network trips to be accurately reproduced. They are ideal to enhance an origin-destination survey and inform the restructuring of a bus network.

Multimodal urban models

Whether strategic or operational, they assess public transport or road projects. You will be able to simulate all mode combinations including new mobilities.

Interurban models

Designed for long distance trips, they allow you to model commuter departure time decision and transfers. These models provide accurate estimates for each period of the day.
