As a new way for traffic evaluation, the technology for road network reliability evaluation can measure the travel time and connectivity reliability of road networks more accurately than traditional technology. In recent years, it has received growing attention internationally and developed at a rapid pace.

The Project on Key Technologies of Modern Central City’s Transportation and Management looked into this technology under the auspices of the National Key Technologies R&D Program. The project is carried out by the Beijing Transportation Research Center which developed an evaluation system of urban road network reliability.

Through analyzing the travel time reliability of Beijing with respect to different time, dates, roads and regions, the system simulates and evaluates the reliability of the Olympic transport lines, gives suggestions on corresponding traffic organization and guarantee measures, and provides reference to the Beijing Municipal Committee of Communications.
