Monitoramento de impacto de Polos Geradores de Viagens: estudo de caso de uma instituição de ensino superior em Manaus

Abstract

The Brazilian cities development was marked by accelerated urban population growth, due to the rural exodus. This population began to occupy the regions peripheral resulting in the expansion horizontal´s city. As result there were significant damages to the quality of life and impacts on the capacity of displacement. The urban planning, proper regulation of the use and occupation land, monitoring the access and services impacts, and the management of road access are instruments that can mediate the demands of trips generated in cities, they are a balance on conditions of mobility and urban accessibility. This research aims to carry out a case of study with a Trip Generator Centers into a type of Institution of Higher Education, which allows to suggest to the government of monitoring the impacts caused in the mobility of Manaus after the project horizon. The literature analyzed about Trips Generators Centers, municipal rule, the project criteria presented for approval by municipal executive government of traffic and comparison with other capitals, field surveys in the following perspectives: vehicle flow volume with categorization, pedestrian flow, waiting time in vehicle queue, queue size, number of stops for pedestrians, search for speed of travel and level of road service. This study identified in the research carried out, that there is no regulation of monitoring the impacts of Trip Generator Centers after project horizon, in addition, it was observed that in the academic period there is an increase of 40% traffic volume of the area comprised by several Trips Generators Centers. Regarding the Institution of Higher Education flow, the impact of the two garage buildings installed in Joaquim Nabuco avenue, equals 22% of the total volume of 4,217 automobiles, with an average row size of 9 vehicles in the Trip Generator Center A and the waiting time of 3 minutes, with maximum of 23 minutes, in Trip Generator Center B, the average value of queue size of 7 vehicles and the average waiting time of 3 minutes, with maximum of 23 minutes. The service level indicator shows that when the Institution of Higher Education schooling period occurs, the quality of the circulation in the Joaquim Nabuco avenue leaves service level D and goes to F, which means that flow with extremely low speeds in urban streets. What the theory indicates is likely to be, congestion occurs at intersections in places with critical signaling, with high delays and volumes, in addition to extensive queues, which is evidenced by the events occurring in the route and identified by the monitoring, with extensive queues occasioned by the Institution of Higher Education. The results indicate the impact generated by these Trip Generator Centers as well as mobility, in the Joaquim Nabuco avenue located in the city´s central region, and reinforce the need to regulate a process suitable to monitoring of Trip Generator Centers and realization off access management road in urban areas.
