Abstract

City clusters and metropolitan areas in China are flourishing in the midst of the deepening urbanization in the country, thereby resulting in the emergence of intercity rail transit. Intercity railways connect mainline and urban railways for an integrated regional transportation system that underpins and leads the development of city clusters and metropolitan areas. This study explores the development mode and service characteristics of intercity rail transit, as well as proposes overviews on this system and prospects of its future technology in China.

CharacteristicsRegional intercity (typically over 100 km)Suburban intercity (typically below 100 km)
Scope of applicationBetween major cities in one city clusterBetween big city and its satellite cities
Service objectIntercity commuting and business travel of medium distanceIntercity trading, schooling, and commuting of short distance
Passenger flow Evident tidal phenomenonSubstantially prominent tidal phenomenon and transportation in city centers
Service levelOne-way travel time of under 2 hEntire travel time of approximately 1 h; focuses on convenience
Operational organizationWith multiple operation modes; operating on main lines or dedicated intercity lines to build hour economy circles in city clustersTo build hour economy circle by intercity lines and suburban lines, bus-mode operation supplemented by trans-station and point-to-point stopping modes
