1. Analysis of triage and care for women victims of road accidents
RESUMO Objetivo: analisar o fluxo do atendimento a mulheres vítimas de Acidentes de Transporte Terrestre (ATT). Método: estudo descritivo, com 782 mulheres vítimas de ATT, classificadas pelo Sistema de Triagem de Manchester (STM), entre 2015 a 2016. Analisou-se o perfil sociodemográfico e o tempo entre as etapas do atendimento, bem como o local de aten

2. A Prediction Model for Night Recovery of Embarked Aircrafts Based on System Dynamics
ABSTRACT: In order to make a sensible prediction on the air traffic flow management with conditions of wave-off and bolter, a system dynamic model for the night recovery operations of embarked aircrafts is built to ensure the adaption of air traffic flow with the capacity of air control at each phase of the recovery operations. The model aims at the characte

3. COLUMN GENERATION BASED ALGORITHMS FOR THE CAPACITATED MULTI-LAYER NETWORK DESIGN WITH UNSPLITTABLE DEMANDS
ABSTRACT We investigate a variant of the Multi-Layer Network Design problem where minimum cost capacities have to be installed upon a virtual layer in such a way that (i) a set of traffic demands can be routed AND (ii) each capacity (subband) is assigned a route in the physical layer. The traffic demands cannot be splitted along several paths (nor even sever

4. Simulation model of discret events applied to the planning and operation of a toll plaza
AbstractThis work investigates the congestion and traffic flow in a tool plaza, and proposes a methodology for the classification of highway flows and its service levels based on a combination of the Highway Capacity Manual – HCM and Discrete Events Simulation fundaments. The proposed mesoscopic simulation is used to analyze service levels of different phy

5. DECISION WITH ARTIFICIAL NEURAL NETWORKS IN DISCRETE EVENT SIMULATION MODELS ON A TRAFFIC SYSTEM
ABSTRACT This work aims to demonstrate the use of a mechanism to be applied in the development of the discrete-event simulation models that perform decision operations through the implementation of an artificial neural network. Actions that involve complex operations performed by a human agent in a process, for example, are often modeled in simplified form w

6. A DISTRIBUTION FOR THE SERVICE MODEL
ABSTRACT In this paper, we propose a distribution that describes a specific system. The system has a heavy traffic, a fast service and the service rate depends on state of the system. This distribution we call the Maximum-Conway-Maxwell-Poisson-exponential distribution, denoted by MAXCOMPE distribution. The MAXCOMPE distribution is obtained by compound distr

7. Operation Efficiency Assessment Model of Route Network in Terminal Area
ABSTRACT: Terminal area is an important part of airspace system. Its operation efficiency is related to the safety, order and efficiency of the entire air traffic. So the assessment of the terminal route network operation efficiency is needed. Considering the aspects of route segment capacity, flight flow, workload and operation stability, the paper analyzes

8. Predictive modeling of entry flow at rotary intersections in Akure, a developing city and capital of Ondo state, Nigeria
Abstract Predictive models for entry flow at rotary intersections in Akure - a developing city in Nigeria- have been developed. Data were collected at the intersections critical to traffic flow in the study area using a cine camera placed at a vantage point from the road sections during peak and off-peak periods in week days. Entry flow (qe) was modelled as

9. Developing corridor choice model under hypothetical Variable Message Sign based traffic information
Abstract The article presents development of a closed-form corridor choice model under hypothetical variable message sign (VMS) based traffic information. A single VMS board is assumed to display traffic information at a junction of two alternative and competitive traffic corridors connecting two catchment areas in Kolkata city, India. The corridor choice mo

10. Stress-based fatigue reliability analysis ofthe rail fastening spring clipunder traffic loads
Nowadays, the rail fastening systems play an important role for preserving the connection between the rails and sleepers in various conditions. In this paper, stress based concept is used to develop a comprehensive approach for fatigue reliability analysisof fastening spring clip. Axle load, speed and material properties are assumed to be random variables. F

11. Biomonitoramento vegetal da qualidade do ar em Ribeirão Preto - SP / Biomonitoring of air quality with plants in Ribeirão Preto - SP.
The air quality monitoring in Ribeirão Preto is carried out by Cetesb with conventional methods and, until now, no experimental study on air pollution biomonitoring was conducted in the region. The city has a growing number of motor vehicles and is located in one of the most important regions of the country for the sugarcane sector. The frequent burning of

12. AVALIAÇÃO DO RUÍDO DE TRÁFEGO VEICULAR EM ÁREA CENTRAL DE CHAPECÓ SC / EVALUATION OF VEHICULAR TRAFFIC NOISE IN CENTRAL ZONE CHAPECÓ SC
The development of cities and population growth have led, among other urban problems, the increase in sound pressure levels of environmental noise. With the overcrowding of cities, the roads start to host large flows of vehicles, among other sound sources. These factors, coupled with the layout and massing of buildings, make the road a polluter responsible f
