Travel demand is critical in transportation investment decision making. Transportation modeling involves developing and applying traffic and travel demand models to identify transportation infrastructure needs, evaluate proposed projects, and optimize existing systems. Transportation modeling helps improve traffic flow, reduce congestion, enhance safety, and promote sustainable transportation options. These outcomes contribute to a more efficient and reliable transportation system that supports economic growth and enhances quality of life.

The travel demand model utilizes sophisticated mathematical algorithms to simulate and estimate travel demands, forecast traffic volumes, speeds, and transit ridership on transit routes. It is a powerful tool for evaluating the performance of existing and proposed transportation systems. It takes into account a wide range of factors, including land use patterns; socioeconomic characteristics of the population and employment; and the composition and configuration of the transportation system.

It helps OKI assess the potential impacts of:

  • New development and changes in population and demographic trends
  • Road expansions and transit projects
  • Changes in transportation policies
  • Technological advancements
  • Energy consumption and sustainability

By analyzing different scenarios and policies with the model, we can evaluate their effects on:

  • Congestion
  • Travel times
  • Air quality
  • Overall accessibility

Maintaining and Enhancing OKI’s Travel Demand Model

OKI’s Activity-Based Travel Demand Model serves as the foundation for our transportation modeling efforts. Guided by state and federal guidelines, and our commitment to excellence and innovation, we continuously strive to improve our modeling techniques and stay at the forefront of industry advancements. OKI collects and analyzes traffic and travel data to ensure the model reflects the unique characteristics of our region. We work closely with DOTs, local governments, transportation agencies, and stakeholders to ensure our models align with their needs and priorities.

Informing Transportation Planning, Studies and Air Quality

OKI’s travel demand model has been frequently applied in various transportation planning and traffic studies and air quality analyses. The model is used to simulate different scenarios and evaluate the potential impacts of proposed transportation projects. This allows us to assess changes in traffic volumes, travel patterns, and congestion levels. This helps us make informed decisions about infrastructure improvements and traffic management strategies.

OKI uses traffic and travel data to analyze air quality within our region. By integrating emissions factors and travel behavior information into our modeling efforts, we can assess the environmental impacts of transportation activities. This analysis enables OKI to evaluate the conformity of transportation projects, which ensures that our region’s transportation network is efficient and effective, as well as environmentally sustainable.
