However, despite the inevitable dance numbers, is increasingly relevant methodologies have reached

Behind every demonstration in the street, the same ditty: figures of participation data by the organizers and the local police data differ considerably, even a few thousand people (1). However, counting becomes number plate checker so controversial as necessary either to have idea of the success of the call, or at least the figures we have at hand, whether to order the use of streets and roads, getting to try even, load capacities of that public space. In this case and in other types of civic activities in public, is having to manage.
However, despite the inevitable dance numbers, is increasingly relevant methodologies have reached for counting or estimating that enable managers and parties gain consensus on the magnitudes resulting beating, then, release of data for large spout without any scientific basis or based on perceptions and / or intentional or purely speculative guesswork, especially when, on the other hand, has an essential function metering in the management of public policies, number plate checker which recognize demand or intensity of use of space in large human concentrations (basically a matter densities), mainly in terms of extracting efficiency indicators. Therefore, it is necessary to abstract from the general connotations of passion, which must correspond to the controversy, above all, a logical debate. This logic has helped unleash, some years ago, an interesting literature on the art of loving crowds, as well as more sophisticated technologies applied to statistical estimates.
Counting a manifestation linear encabida a scheduled trip and one-way, can be done by modern number plate checker detection systems based on aerial image (2) or, more modestly, with samples number plate checker in a particular section of walking at different times it ends, then, based on averages, extrapolated to other times and places (3). So, being rationally acceptable methodologies, consensus on those and the formula for counting should be possible to avoid any exaggeration of fact or desvirtuació properly number plate checker studied. Surely the question of recognition of these counts must be linked to the transparency of the media and methods used even looking if necessary (if possible) a being "fair" for the implementation of the measure ( perhaps number plate checker pointing to a type of audit quality ex ante?) or allowing a co-management form of measurement, or simply counting is done openly. Although controversies are inevitable, logical solutions must not be trivial at all for technicians, who are always responsible for the management, number plate checker and as the total estimate may be off other useful number plate checker calculations number plate checker related, for example, the channel mobility in public transport or economic impact on commercial establishments or restaurants close to the event, or the calculation of the cost of the necessary means for the management of the event itself, or even the qualitative effects to other levels.
Nevertheless, apart from political or trade union demonstrations, the spectrum of these methods is also applicable to other mass events, occurred in public open spaces, number plate checker more prosaic, perhaps less passionate and often holidays : from simple calculation using a vial peatonalitzat, to encrypt the number of people in a fair outdoors and / or develop a set of streets of a city (contemplating multiple doors input / output, number plate checker multiple routes or in different directions), which are essentially based on, for example, number plate checker studies of mobility.
Let's look at a practical example: a fair old theme in a Catalan town. Imagine a fair held every year in the village on specific dates throughout the weekend and having to re-mark the importance of a central aspect of tangible or intangible assets of the city (eg in Terrassa with Modernista Fair, the activities have been combined with special emphasis on the urban environment unique number plate checker architecture of public buildings and factories and commercial number plate checker establishments, or eg nth medieval fairs that have multiplied in recent times many Catalan towns emphasis in the past Romance) or creative or innovative character (eg, Vic, with live music market, or Tarrega with its Fair Street Theatre, in celebration of concerts performances throughout the
