STUDIES
Traffic Studies – RIT
The traffic study aims to offer analytical data and systematized information regarding the studies carried out to prepare the Traffic Impact Report - RIT for different types of projects, emphasizing in essence, the impacts on the road system, especially quantifying and analyzing the changes in the operational performance of the main roads surrounding the aforementioned complex, which will serve as access to the site.
Therefore, this report addresses the studies developed in relation to the system external road adjacent to future developments, with regard to their physical and operational conditions; access routes and traffic distribution generated by the different access alternatives; estimates of travel generation related to the insertion of the future enterprise; the impact on traffic due to new trips associated with those already on the roads; the assessment of the road capacity of the surrounding roads and the operating service level of these roads and the necessary mitigating measures, aiming to preserve and optimize the conditions of fluidity, safety and comfort for users of the external road system.
Neighborhood Impact Studies – EIV
The Cities Statute, through Federal Law 10,257, defines the Neighborhood Impact Study – EIV – as an instrument of urban planning and control, with the purpose of analyzing the absorption of urban projects by the environment in which they will be inserted, and in seeking to avoid damage to the population's quality of life, urban land planning and the environment. In its article 37, it also allows the analysis of the impacts of new installments and projects, listing some items to be analyzed, such as:
•Population density;
•Urban and community facilities;
•Land use and occupation;
•Real estate valuation;
•Traffic generation and demand for public transport;
•Ventilation and lighting and their effects on neighboring buildings;
•Noise generation and other effects on the environment, including relating to security;
•Urban landscape and natural, cultural, historical, landscape and architectural heritage;
•Installed urban infrastructure and the needs for its expansion.
Assessments vary depending on the size and activity of each enterprise, which are called travel generating hubs – PGV’s. The Neighborhood Impact Study was created with the purpose of analyzing and evaluating the absorption of urban projects by the environment in which they will be inserted and proposing mitigation and/or compensation measures.
To carry out concrete actions inherent to the EIV, it is necessary to implement the guidelines for land use and occupation that are established by the Master Plan. Both the Master Plan and the EIV are territorial planning instruments that must precede and prevent disorderly urban expansion and, if possible, be implemented simultaneously due to the complementarity that exists between these two instruments.
Road and circulation study
Analytical study of circulation of the road system and points critical nodes, proposing, when possible, changes in the direction of roads, always prioritizing active modes of transport (walking and cycling).
The objective is based on engineering actions to relieve traffic on some roads, creating new options for more direct routes and linked to a coherent horizontal and vertical road signage scheme, with the aim of making both the inhabitants' routes clearer and safer. .
Understanding travel generating hubs in local dynamics, if they present some bottlenecks nearby, as well as reading local circulation, return movements and block loops to better distribute the traffic generated without causing negative impacts. Furthermore, definition of areas of influence to better understand urban dynamics and identify critical points.
Traffic simulation
Traffic simulation is a virtual process that aims to The objective is to simulate the individual behavior of vehicles and drivers within a road network. Due to the randomness and complexity of traffic, the simulation helps to understand traffic patterns, through parameters such as: headway, spacing, lane changes and others. This behavior is used to predict the likely impacts related to changes in traffic patterns resulting from changes in traffic flow or changes in the physical environment, such as the number of lanes, signage and others.
There are, generally speaking, two major areas in traffic simulation.
•Traffic Microsimulation
•Traffic Macrosimulation
The first refers to the process of creating a virtual model of the transport infrastructure of a city or region with the purpose of simulating the interactions of road traffic and other forms of transport at a microscopic level of detail. The most used options are: Car-Following and Lane Changing.
The second option deals with understanding on a macro scale, involving the public transport network, traffic zones, whose parameters are: characteristics of each zone; mathematical modeling to address travel patterns; balance of the Origin – Destination matrix, among others.
