Introduction: Active modes of transport can be defined as means of travel and transport at reduced speed, which take up little space on public roads and do not emit air pollutants or noise, being seen as an economic, social, and environmental asset, and a real alternative to motorized vehicles. Given its characteristics, the environmental benefits retrieved from active modes of transport should not serve only as a justification for its promotion but as a decisive and active factor in the scope of its actual use, which translates into the provision of pleasant and less polluted routes. Thus, the main objective of this paper is the development of a model for planning and generating urban routes for active modes that have a less negative influence on active users (pedestrians and cyclists) regarding their exposure to air and noise pollution. Methods: Conventional route planners are mostly designed to find the shortest, fastest, or less expensive route. In this research, the model to assign the best route will be presented for pedestrians and cyclists from an environmental point of view, by defining the least polluted, less noisy, and most health-friendly path. Based on the production of noise and air pollution maps, the model proposes the contamination of the network routes, which are used to determine healthoriented routes. The model is carried out through the calculation of the noise and pollution exposure for the routes found, compared to the shortest route. Conclusion: It was possible to conclude that less polluted routes may imply a small increase in the length of routes, but a significant gain in terms of reduction in exposure to PM10 and noise for active modes. Thus, the use of health-friendly routes can be seen as a matter of public health and a way for promoting more sustainable mobility.
