Trajeto ao menor risco – modelo de análise / avaliação

Abstract

The increase in the circulation of vehicles in Brazilian cities has come with the increase in the number of incidents in public streets. Some of these claims are targeted specifically at automobile drivers, such as theft of vehicles or belongings of their occupants, while others that are unrelated, such as the occurrence of shootings, but also affect drivers. Also, the formation of risk areas around well-defined points of conflict has also been growing in cities. There are many cases of drivers who enter involuntarily some streets within regions of conflict and suffer unexpected setbacks. So, the need to evaluate the quality and the risk of the available route options is increasing. Therefore, this project aims to present a process that helps the driver of the vehicle to quantify and analyze the level of risk associated with each of the options of route between the desired starting and destination points. The process begins registering the risk areas of a city, associating each of them to a risk rate for traffic time in its tracks. The curves defining the risk areas must be integrated with the roadmaps provided by the geo-referencing software used to obtain the recommended route options. So, a process is defined to, for each request of alternatives for carriage between two points of a map, usually based on the shortest travel time and / or the shortest distance; also calculate the cumulative risk in each option of suggested route, according to the risk areas crossed and the time of travel. Finally, with the weighting of distance, time and risk data of each route option received, a final quality score for each one is obtained.
