The number of entries has decreased: after the system implementation, in September of 2012, 219 vehicles entered the LTZ, which is an average of 8,76 vehicles per day as opposed to the 20 vehicles prior to the system implementation. As for the noise assessment, the measurements conducted revealed a decrease of 4,1 Db during the day. Also, there was an increase of 8,3 p.p in the percentage of people that considers the automatic control system very useful (2011 and 2012). The evaluation also included a traffic count that was carried on before and after the implementation. Before the implementation, the traffic counts revealed that 20 cars entered on a daily basis, while after the implementation, 8,75 vehicles entered the limited access zone.
Furthermore, the new access control system has contributed to a better management of the LTZ, since it allows the Municipality to control the access remotely and prevent all sorts of abuse. Additionally, the software collects a lot of data, such as the number of entries, parking time and vehicle classification, among other indicators.
