Traffic Engineering

Within the scope of traffic engineering studies, short and medium term solutions are developed by analyzing the transportation problems experienced or anticipated in cities at micro and meso scale.

In this context, studies are being carried out, such as:

  • Traffic counts
  • Traffic analysis and simulation studies
  • Geometrical arrangement and circulation studies
  • Signalization projects and analysis studies
  • Corridor analysis
  • Traffic impact analysis
  • Bicycle lane projects

Within the scope of traffic counting studies, counts in the details listed below are obtained:

  • Intersection Counts
  • Section Counts
  • Control Counts
  • Pedestrian Counts
  • Passenger Counts
  • Cordon/Screen Line Counts
  • Macro, micro and mezzo modeling studies
  • Analyzing the current situation at intersections with simulation and revealing the deficiencies
  • Testing the arrangements on intersections and road sections with simulation
  • Simulation of squares, pedestrians, trains, trams, subway and metro-bus
  • Travel time detection and delay analysis studies
  • Speed analysis studies
  • Conducting saturated flow studies
  • Preparation of circulation projects on the road where traffic circulation is required based on the results of counting, analysis and simulation studies,
  • Measuring the lanes and the widths of the traffic islands and making the necessary arrangements on the project,
  • Making horizontal-vertical markings,
  • Identifying the road sections suitable for the expansion and making the necessary expansion or narrowing when needed,
  • Making arrangements in problematic points and intersection areas,
  • Making horizontal-vertical markings as required by geometrical arrangements,
  • Arrangement of fuel station, shopping center, public buildings, entry and exit to parking lots, cab stands on the project,
  • Arrangement of roadside parking areas,
  • Arrangement of bus and minibus pull-off areas.
  • Signal phase diagrams
  • Signal time optimization studies
  • Signal coordination - green wave studies
  • Smart intersection work

Corridor analyzes are carried out along the intersections that interact with each other on certain arterial roads within in the city.

Following identification of the current situation and problems by using various data collection methods on the determined highway routes, designing proposal ideas projects and testing them with micro-simulation method and evaluating the improvement alternatives along the corridor according to various criteria.


Impact analysis studies make significant contributions in identifying potential transportation problems before the development of significant real estate projects.

Traffic impact analyzes of ISBAK are carried out using international traffic engineering methods, and are prepared in accordance with the standards stipulated by local governments, credit institutions and foreign investors. Turkey’s largest real estate investment interaction analysis is carried out by ISBAK in an objective and professional manner.

After the facilities such as Mixed-Use Real Estate Investments, Tourism and Entertainment Center Investments, Shopping Malls (AVM), Housing and Office Projects, Tunnels, Ring Road, Airport, Public Transportation (Subway and BRT) Projects are opened and in the coming years, traffic impact analysis in places where potential problems may occur is required before the projects.


“Micro mobility” is one of the concepts that has recently come to the prominence in transportation. Bicycle lanes are one of the most important infrastructures of this concept.

  • Determining the need for bicycle lanes, conducting feasibility studies and designing bicycle lanes,
  • Connecting public transportation stations, stops, piers with dense passenger movements, and park-and-go systems,
  • Improving the conditions of travel by bicycle, providing a safer and more comfortable cycling in the region,
  • Making application projects on the determined bicycle lanes.
