Kocaeli Short Term Transportation Traffic Improvement Studies and Projects

Within the scope of 2025 Kocaeli Transportation Master Plan (KUAP) and Preparation of Priority Mass Transportation Systems Preliminary Project and Feasibility Studies, necessary studies and censuses were made on the existing road transportation system, and recommendations and regulations were prepared that would set a framework for transportation demand management.

Recommendations for the highway network have been prepared within the framework of the following basic principles: removal of freight traffic and transit traffic from the city center, decontamination of city centers and ensuring effective and efficient use of capacity.

Within the scope of the study, "Intersection Arrangement Suggestions", "Corridor Based Analysis and Suggestions", and "Suggestions and Evaluations for Investments and Projects" were prepared for urban transportation infrastructure.

Throughout Kocaeli City, traffic counting studies were carried out at 65 intersections and route sections consisting of the intersection of roads known to have certain traffic volume values in the regions where central settlements and attraction centers are located. Necessary arrangement and signaling studies were carried out for each intersection within the scope of KUAP recommendations.
