Abstract Youngjun MOON et al. The Korean Government seldom expands SOC Investment for road construction according to both the Low-Carbon Green Growth Policy implemented by the previous administration and Creative Economy for National Happiness Policy by the current administration. This limitation on new road construction brings not only traffic jams and congestion by increased numbers of vehicle to cities, but also safety and environmental issues by the emission of greenhouse gas. Taking these realities created by the government policy changes, there is a claim to maximize the transport efficiency of the current road system. During the last 20 years, intelligent transportation systems (ITS) were established in major metropolises. It is also expected to have interactions between intellectualized and safety-improved vehicles and road infrastructure in a later stage. Like this, factors and conditions are changing in road transport operation that will lead to increased
road efficiency and finally road capacity. ITS based on linkage between roads and vehicles has evolved gradually and will develop system optimization that enables strategies for user optimization and traffic demand control through real-time information, managing total traffic volume, and controlling traffic networks. Furthermore, cooperative adaptive cruise control (CACC) will be commercialized in the near future by the evolution of domestic and overseas research, resulting in greatly impacting road capacity. However current traffic models, such as the road volume calculation model, hardly reflect volume changes occurring under operation of ITS technology. Accordingly, research is needed on a new model that can reflect an increase of road capacity based on ITS operation. For this, this research proposes one model that focuses on traffic volume analysis and reflects changes during operation of ITS technology. This research analyzed the development trend of advanced ITS technologies that have influence on road volume and its models and reviewed ITS technologies such as CACC. In order to reflect the effects of volume increase of such ITS technologies, the research analyzed limitations in the methods of capacity analysis proposed by the current road capacity manual and suggested improvements. In particular, this research recommends a volume calculation model for consecutive-flow highway sections and short-flow signal intersections. It also conducted a simulation materializing advanced ITS technologies to identify the influential effects that advanced ITS technologies have on road capacity. Based on the simulation results, this report finalized a volume calculation model that can reflect ITS operational effects and suggests its applications. This research reflected advanced ITS technologies into the road
volume calculation model, which can be operated by updated paradigms based on the link between roads and vehicles. It has significance in terms of a viewpoint that it procures from the current limitation to analyze road capacity around road and traffic conditions and then reflects ITS technology influences on road capacity. Taking government policies and present road infrastructure, road expansion is reaching a breaking-point requiring government promoted next generational ITS technology development. This research is just an initiation for the solution and is limited by the usage of simulation results that materializes certain forms of geometry and assumptions. In the future, it should be credited by applying various ITS technologies and geometries, and obtaining data from real sites through calibration and validation of the model. This research attempts to contribute to future research where it identifies the effects of high-tech ITS technology on the road system and suggests solutions based on said effects.
