Advanced traffic information data-based urban mobility analysis and its utilization for policy making
Advanced traffic information data, which are collected by intelligent transport system (ITS), provide real-time traffic information. They have been mostly been used to maximize the efficiency of urban traffic management, but have been inadequately utilized for transport policy making including transport planning and assessment.
￭ Advanced traffic information data are traffic information data collected every second for 24hours a day by means of ITS. Since they allow for the diagnosis of urban mobility and monitoring of time series changes without time and space limitations, these data can be very useful for drafting transport policies.
￭ Building on the characteristics of advanced traffic information data, this publication will present empirical analysis cases including road bottleneck point analysis, corridor analysis and yearly mobility change analysis.
Developed countries have built a basis for utilizing advanced traffic information data in the phase of ITS introduction.
￭ The US has laid out a standardized data management system for advanced traffic information data, and developed and supplied an analysis tool, while conducting an analysis of urban mobility through mobility monitoring program and issuing the corresponding monthly reports.
It is suggested to draw up a wide range of policy proposals and provide support for them to use domestic advanced traffic information data for drawing up transport policies.
￭ Notably, as most of the advanced traffic information centers at municipalities do not manage advanced traffic information data in a proper way, they are scrapping those data on grounds of lack of data storage.
❶Urban mobility monitoring management and analysis tool (tentatively named) based on advanced traffic information data should be developed and supplied by the central government to enhance the use of advanced traffic information data by local governments. In addition, a standardized mobility assessment indicator should be drafted and data management system should be beefed up.
❷To expand the role of advanced traffic information centers in local governments in drawing up transport policies, it is suggested to develop mobility assessment indicators and an interconnected system for their effective connection with road policy or public transport policy.
❸Besides, it is recommended to bolster the collection system for traffic data, a gauge of basic assessment of urban mobility, to evaluate urban mobility based on advanced traffic information data and issue monthly or annual reports, and recruit analytic professionals.
