Project Description:

Osmaniye, which is one of the most important cities of the Mediterranean Region in terms of its historical, cultural features and geographical location, causes significant problems in urban transportation due to factors such as rapidly increasing population, labor, vehicle ownership, new settlement areas opened to construction and increasing traffic congestion in summer months with a focus on tourism, as well as the expansion of borders. The necessity of an urban transportation plan in which the principles of sustainability and environmental sensitivity are taken into consideration and the issue of social justice is taken into consideration is emerging to eliminate the problems in urban transportation.

The Transportation Master Plan (TMP) is one of the most significant studies in the era of transportation planning in every populated city. For the Osmaniye TMP project, a 4-steps travel demand model as a ubiquitous framework was adopted. The project consisted of the following phases:

Phase 0: Evaluating the performance of the current transportation network and examine the available data

Phase 1: Large-scale data collection. Collected data consist of:

• • The household survey (the sample covers over 5 percent of the population)
  • Passenger surveys (pedestrians and drivers)
  • Measuring the transportation network features (geometric design of transportation network elements and specification of public transportation)
  • Junction and screen line traffic counts
  • Land use, population, and employment attributes of Osmaniye city

Phase 2: Preparation of data description report which gives useful information about travel behaviour patterns and socio-economic attributes of people

Phase 3: Calibrating a 4-step travel demand model which consists of the following sub-models (the model is calibrated by expert transportation planners using Visum macro-simulation software)

• • Trip generation
  • Trip distribution
  • Modal split
  • Traffic assignment

Phase 4: Forecasting future travel demand of Osmaniye

Phase 5: Generating transportation policies to make a suitable balance between future travel demand and supply in Osmaniye

Phase 6: Evaluating policies and propose selected policies

Finally, a multi-modal approach that provides the greatest benefit to the overall transportation system has been recommended as the preferred transportation solution for Osmaniye.
