"It is not surprising, since according to the Openstreetmap database, it is the city of the sample with the highest ratio of kilometers of public transport per inhabitant (7.35km)," says the search engine in his study in which however, they are not all for the island network.

To assess the quality of the public transport network in each city, Holidu has analyzed the efficiency of a total of 4,957 trips, an average of 84 public transport journeys per population.

Next, a number of points have been set, proportional to the diameter of each ring, and the duration of the trip from each of them to the center has been extracted, along with the percentage of walking distance involved.

The data for each city has been aggregated by calculating the median speed and the average percentage of walking distance by city. Then the duration and journey data have been normalized on foot and each city has been assigned a score that is higher the faster the public transport and the fewer users have to walk to get to the center. It has been attributed a weight of 70% percent to speed and 30% to the proportion on foot.

The information per route was obtained from the Google Directions API. Only public transport routes that yielded a valid result were included in the calculations. Only routes within each city were considered, excluding those related to neighboring populations. A minimum of 15 itineraries per city was established to consider the representative score. The time and date of departure of all the routes analyzed was on October 7, 2019 at 8:30 in the morning to test the public transport network at a peak of demand. The 55 most populous cities in Spain have been taken into account for the study. The data related to the ticket price per route has been extracted from
