Evaluation Giro Gelderland 2016

Commissioned by the province of Gelderland and the municipalities of Apeldoorn, Arnhem and Nijmegen, an evaluation has been commissioned for the start of the 99th Giro d’Italia Gelderland. The evaluation report was compiled by researchers of the University of Arnhem and Nijmegen (HAN). Decisio contributed to the evaluation by analysing the number of visitors of the event. The research report “Evaluation Giro Gelderland 2016” is publicly available.

Visitor Analysis

For the evaluation, Decisio was responsible of the estimation of the number of visitors to the presentation team in Apeldoorn and the first three stages of the Giro. These are made on the basis of mobile data surveys that have been conducted during the event. It is also addressed the number of additional visits in Apeldoorn, Arnhem, Nijmegen and the whole Gelderland.

Number of visitors determined using mobile data

The use of mobile phones makes possible to count the number of visitors and their origin anonymously. During the day, a mobile phone (through phone, SMS, using apps etc.) is used dozens of times. In the use, data on time and geographical location is recorded. For this task, Decisio has worked with Mezuro.

Mezuro analyses daily the data from Vodafone mobile network and thus the movement of millions of mobile phone users. In this way, the pattern of orgins and destinations of Dutch and foreign mobile phones from Vodafone are recorded countrywide and 365 days a year. This data in the incremented by Mezuro with so-called “multiplication factor” to reach a representative picture of all the Dutch.
