Quetzal is an open-source solution offering a framework and algorithms for the development of your transport models. <\/h4>\n<\/div>\n\n\n\n
\n
<\/div>\n\n\n\n

Developed since 2016 by SYSTRA\u2019s 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. <\/p>\n\n\n\n

<\/div>\n\n\n\n

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.<\/strong><\/p>\n\n\n\n

TRANSIT ASSIGNMENT MODELS  <\/h3>\n\n\n\n

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.<\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

MULTIMODAL URBAN MODELS<\/h3>\n\n\n\n

Whether strategic or operational, they assess public transport or road projects. You will be able to simulate all mode combinations including new mobilities.  <\/p>\n<\/div>

INTERURBAN MODELS <\/h3>\n\n\n\n

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.<\/p>\n<\/div><\/div>\n\n\n\n
