The integrated model allows the understanding of travel demand and market segmentation using Cube Voyager (macro-model) but captures the detailed operational congestion effects using Cube Avenue (meso-model). Having the integrated model built on the Cube modeling platform allows the model developed for this study to now be a resource for the agency.

THE CHALLENGE

In 2010, THI was commissioned to conduct a transportation planning study for a system-wide, gateless, electronic toll collection (ETC) system. With a length of 900 KM this would create the world’s largest multi-lane free flow ETC system. The project needed to incorporate the operational aspects of proposed traffic management strategies while also modeling the entire Taiwanese expressway network.

THE SOLUTION

THI was able to create a state of the art integrated model in Cube using the macroscopic demand modeling capabilities of Cube Voyager with the mesoscopic operational capabilities of Cube Avenue. With this model they were able to:

  • Simulate the operational impacts of traffic management scenarios to understand queues and bottlenecks on the roadway segments which spill back impeding upstream traffic flow.
  • Forecast intercity travel demand considering growth of the population, demographics, auto ownership, and the co-opetition of different operators.
  • Evaluate the impact of major alternative transportation infrastructure projects on traffic flow, including:
    • New high-speed rail stations
    • Transformation of the Taiwan Railway into Rapid Transit System
    • Taoyuan International Airport Rapid Transit
  • Test pricing strategies and assess the future financial performance of the National Freeway Construction & Management Fund.

The study was conducted by Ian Lee, Jin Wu, and Jeff Yang of THI. THI Consultants Inc. headquartered in Taipei, provides professional services in the planning, engineering, operations and management of transportation as well as land development projects. THI has overseas offices in Shanghai, Hong Kong, and Macau. THI was established in 1989 by founders who had a vision for improving the quality of life for their native land, as well as other parts of the world.
