How many people can the impact of a poster pasting reach in the center of a large city?

To get an idea of the reach it could have, we take as a reference the report on the widening of sidewalks on Gran Vía, which the City Council made public. They installed two pedestrian capacity controls at numbers 13 and 27 of the street (next to the intersection with Clavel Street and in front of Primark, respectively). The results are spectacular, with peaks of up to 7.300 people per hour walking along Gran Vía.

Pedestrian traffic on Gran Vía in Madrid has been gradually increasing in recent years, especially during the afternoon/evening period; specifically, more than 3.000 pedestrians circulate during peak hour on the odd-numbered sidewalk. The data is overwhelming: with the widening of sidewalks during the last holiday period, the number of pedestrians reached 7.300 per hour at some points and more than 76.000 per day during Christmas 2019.

The greatest intensity of pedestrians occurred in the afternoons, from 18.00 to 20.00 hours, on the even-numbered sidewalk, next to the block where Primark was installed. In addition to this figure, we must take into account the movement of pedestrians and vehicles in the surrounding areas such as Chueca, Malasaña, C/ Fuencarral, C/ San Bernardo, Plaza de Santo Domingo, C/ Preciados, C/ Mayor, C/ Arenal, Puerta del Sol, C/ Atocha, C/ Jacinto Benavente, La Latina, or C/ Huertas, among others.

Knowing exactly the impact of a poster pasting throughout the center of Madrid is impossible, so we leave this information open to your personal assessment, so that you can estimate whether it is really worth doing a poster pasting in Madrid.
