Today, transportation has become an important part of everyone's life. People feel all its issues and problems closely and seek solutions to overcome its challenges. Therefore, a professional and technical view on this issue is very important

With \"transportation planning\" to improve the current traffic situation in each area, appropriate scientific and technical decisions and solutions have been adopted and the future needs of the network at different levels can be predicted

Since humans and vehicles are the main components of transportation, any alterations  in traffic conditions has a direct impact on the micro and macro level of the economy and can bring potential benefits or harms to the investor or country at  the enterprise and national levels such as

*Changing travel time and considering the economic value of travelers' time during travel

*Changing fuel consumption and its direct relationship with  economic issues

*Possibility of creating employment in this field according to the scope of related fields

*Possibility of providing direct income from some areas oftransportation by selling tickets, receiving tolls, etc

In addition to the above, transportation is closely related to social issues, development, environment and passive defense, etc. Increasing social justice and eliminating deprivation from the region is achieved by providing access to transportation infrastructure in an area. Establishing balanced development in different sectors will be achieved through the use of equal transportation facilities throughout the country. Environmental protection is one of the important categories in this field by paying attention to the non-passage of transportation infrastructure through environmentally protected areas and reducing the production of air pollutants

In the field of macro-planning, transportation is related to other specialties such as urban and social, financial and economic planning, etc., and it is also affected or influenced by them. From a technical and professional point of view, traffic engineering and transportation planning are in direct interaction with the topics of route design, operation and pavement design, and financial and economic analysis

Studies in this field are very diverse and varied such as:

*Studies of the comprehensive plan of transportation and traffic at the national and regional levels

*Studies on transportation organization at the regional and sectoral level

*Studies of mass transportation systems and design of transportation terminals

*Studies of intelligent transportation systems

*Road safety studies

*Studies on organizing and designing urban thoroughfares and intersections

The outputs of the transportation sector vary according to the type of project and can include estimating the travel demand in the future horizons, determining the number of lines passing through the supply system, designing the private, public transportation network, and so on

Metra Consulting Engineers Company, with nearly four decades of experience and service in the engineering sector of the country, has been working professionally in this field for more than two decades by obtaining a grade of transportation and traffic studies and establishing a special department for this study. . Carrying out studies of the comprehensive transportation plan of the country in cooperation with AGIS - the French  Company- conducting studies on organizing and comprehensive

transportation plan in five cities of the country, conducting studies on designing intelligent transportation systems in 3 cities and 3 transportation axes of the country, conducting traffic studies in specific regions Tehran Municipality is only a part of the fruitful and accomplished record of this company in this field

As a part of the company's studies and design elements,this department cooperates continuously with other elements involved in studies and design in various fields of road and railway studies and strives to achieve clear horizons
