The density of traffic within urban areas depends on multiple factors, and among those; one
that has major impact is the weather. This paper presents a study that empirically analyzes
the traffic flow velocity depending on the atmospherically conditions and the day schedule.
The objective is to assess systematically to which extent there is a correlation between the
vehicle velocity on an urban environment and the weather, depending on the time of day.
The presented case of study uses a set of real data, specifically the trips made by taxis in the
city of Porto (Portugal). First, the vehicle GPS routes are analyzed to identify departure and
arrival points and estimate the route average velocity and adding weather and time
conditions. The data is processed with different regressive techniques to obtain the influence
of the variables on the velocity. The results show differences between days of the day and
weekends, as well as differences in speeds with a favorable climate for driving compared to
other more adverse ones.

Traffic in urban environments vary significantly depending on the areas of the city and the
time of day. Nowadays, thanks to the large number of GPS devices that are integrated in all
kinds of devices, it is possible to make a quantitative analysis of traffic. This contribution
presents an application developed to analyse this information in a simple way and with a
visual representation. One of its main advantages is that it is adaptable to any city in the
world, as its internal algorithms adapt to the available data are presenting and adjusting it to
the traffic through the city. This is done by extracting information directly from the data
provided by GPS devices moving around the city. In addition, an analysis of the execution
times of all application processes is presented to determine which parts involve a higher
execution cost and determine the overall scalability of the application.
