Intersection Design  

Geometric design studies of the signalized/unsignalized junctions are conducted based on highway standards (Highway Capacity Manual), which are accepted worldwide. Before implementing signal optimization, signal coordination or a smart traffic system, study area should be examined geometrically and geometric changes should be implemented if needed. More details

Signal Optimization

Signal optimization means calculating the best green times for reducing the average delays in a signalized junction, based on vehicle counts. Traffic counts are collected during peak and off-peak periods. More details

Signal Coordination

The main purpose of signal coordination is to reduce travel times along a corridor by coordinated junction management. This application is generally known as “green wave” and used to reduce corridor travel time, delays and traffic congestion at the junctions on a corridor. More details

Road Safety

Road safety studies include analysis of the traffic accident statistics and black spots, providing solutions to minimize accidents and improve safety. These studies are conducted based on highway safety standards (Highway Safety Manual), which are accepted worldwide. More details

Signal Controller

The main purpose of signal coordination is to reduce travel times along a corridor by coordinated junction management. This application is generally known as “green wave” and used to reduce corridor travel time, delays and traffic congestion at the junctions on a corridor. More details

Traffic Feasibility Studies

Signal controllers are used to control traffic lights at the junctions. Controllers are programmed with manufacturerspecific interfaces. Preparation of the signal programs and selection of the modes (actuated, semi actuated, fixed time and emergency traffic actuated) needs expertise offered by ISSDTM. More details

Traffic Impact Analysis

The aim of the Traffic Impact Analysis study is to evaluate the impact of planned development project’s traffic generation and traffic attraction on the existing transportation system and to estimate future traffic.  More details
 
 

Trainings

 

Traffic Engineering Trainings

This training aims to expose basic concepts of traffic technique and theory in addition to the basic relations behind the methods to be used for transportation planning and traffic management studies. Theoretical matters are reinforced with practical applications during the trainings. More Info

Traffic Simulation Software Trainings

This training aims to model a traffic network, generation of various scenarios by entering the real traffic data into the simulation environment and the analyses of the results. More Info

Traffic Volume Studies

Traffic Volume Studies

Traffic data collection is the first step of all the works on transportation planning and traffic management. ISSDTM uses technology-based methods for data collection such as image-based vehicle counting cameras, number plate recognition systems, drones, fisheye cameras. More Info
