Abstract
Traffic analysis is an essential and complex component Transportation systems and is a quotation. To perform these analyses, there are various analysis tools, each of which is designed based on a specific need. These tools generally differ in their limitations, capabilities, methodology, input and output requirements. The purpose of the Traffic Analysis Tools Selection Methodology is to assist traffic engineers, designers, and traffic operations professionals in selecting the right type of traffic analysis tool to expedite operations. Another goal is to help establish stability. and the uniformity of the analyzes across the state transportation departments and federal/regional/local transportation agencies. Choosing the right traffic analysis tools for a project requires judgment, insight, and knowledge that can only come from years of experience and applications. There is now an expert system that makes the job significantly easier. By answering several questions about the key features of the project, the expert system suggests the type of traffic analysis tool to reach clear, complete and consistent answers that are necessary for transportation investment decisions in society.
1 Overview
Traffic analysis as a necessary and complex component In planning and construction, one of the infrastructure factors is our transportation system. To perform these analyses, there are various analysis tools, each of which is designed based on a specific need. To be used correctly, these tools provide answers with sufficient detail and clarity to inform decision makers about potential positive and negative impacts and alternative solutions. Traffic analysis tools to Choosing the right tools for each job will help. Choosing the right traffic analysis tools for a project requires judgment, insight and knowledge that can only be obtained from years of experience and applications. These tools are still important and are used continuously. Of course, there is now an expert system that makes the job considerably easier. By answering several questions about the key features of the project, the expert system determines the type of traffic analysis tool to reach complete and consistent answers to implement investment decisions in creating healthy (flawless) transportation in the community. In general, these studies show how various types of tools have been significantly effective in solving the wide-ranging problems faced by every society and organization[1].
1-2 Statement of the main problem of the research
With the passage of time due to the development of the country's transportation fleet and the lack of development of other components of the transportation system, this growth has increased traffic congestion, as a result the potential and number of traffic accidents and delays has increased and the quality of life has decreased. Therefore, in order to solve the problems and increase the efficiency of the existing transportation systems, experts should analyze the existing system using traffic analysis tools so that they can comment on the potential effectiveness of a specific strategy. Unfortunately, there is no guidance for using the existing methodology and tools related to traffic analysis in our country, and the studies that have been conducted are very few and very general. This thesis investigates how to know the appropriate analytical methods for choosing an effective traffic model for analytical functions.
1-3 Research question
Which of the traffic analysis tools should we use to ascertain the potential effectiveness of a specific strategy in traffic management?
1-4 Hypotheses
According to the assumptions used in the presentation of travel demand models and taking into account the dominant characteristics of the inner city routes in Tabriz city, the use of these models seems to be more appropriate for traffic design issues.
According to the assumptions used in the presentation and in terms of the dominant characteristics of the existing inner city routes in Tabriz city, the use of these models will be more suitable for traffic planning issues. The analytical methods and software presented in these regulations are aimed at providing a codified method for choosing an effective analytical method according to the existing conditions. This written method can be used by all experts and scientific activists of the country's traffic after conducting a case study in this thesis. All traffic models can be placed in seven general formats. These models include: microscopic simulation models, mesoscopic simulation models, macroscopic simulation models, traffic sign optimization tools, design and planning tools, travel demand model and analytical and deterministic tools. In this thesis, the most effective model is supposed to be Among the seven mentioned models, it is based on input data to evaluate the effectiveness of existing traffic programs in Tabriz city. In general, the methodology of selecting traffic analysis tools to help engineers and traffic operation specialists in choosing the right type of traffic analysis tool to improve operations and also help create stability. An analysis can be done in all parts of transportation.
1-6 practical goals
Providing a codified method for choosing an effective analysis method according to the available conditions from among all the models that can be used for road and traffic consulting engineers and other related organizations such as the Ministry of Roads and Urban Development, municipalities, governorates and governorates, traffic organizations, the Ministry of Interior, and the country's engineering systems.
1-7 Research method
The research method is the use of library and online resources, as well as creating interaction with international companies that produce traffic software and using methods similar to those used in production programs. and also using the method used by FHWA.
1-8 Variables under investigation
Geographic ranges: the study area includes, intersection, road It is one-way, corridor or network. etc. HOV Types of facilities: freeways, on-ramps, arterials, plazas, lanes Modes of travel: single-occupant vehicle, multi-occupant vehicle, bus, train, truck, bicycle, etc. Various traffic management strategies and applications: ramp measurement, sign coordination, incident management, etc. Passenger responses: Passenger reactions to traffic management strategies, such as route deviation, travel time selection, mode change, destination selection, etc. are referred to.
Variables related to traffic measurement: service level, safety measures (accidents, fatalities), travel time, speed, vehicle-travel hours (VHT), and environmental measures (greenhouse gas production, fuel consumption, noise), etc.
Variables related to profit analysis and cost: ease of use, required hardware, required information, animation, etc.
According to the AHP method, the variables will be assigned values ??from 0(completely irrelevant) to 5(completely relevant) in order to find suitable analytical tools for the desired study
1-9 Structure of the thesis
According to the above goals and process, the structure of the thesis is as follows:
In the first chapter, as mentioned, the general statement, the basic research problem, scientific and practical objectives, research method and the investigated variables are discussed. The context has already been explained.
