The master equation approach is proposed to describe the evolution of passengers in a subway system. With the transition rate constructed from simple geographical consideration, the evolution equation for the distribution of subway passengers is found to bear skew distributions including log-normal, Weibull, and power-law distributions. This approach is then applied to the Metropolitan Seoul Subway system: analysis of the trip data of all passengers in a day reveals that the data in most cases…

Modification of the gravity model and application to the metropolitan Seoul subway system.
The Metropolitan Seoul Subway system is examined through the use of the gravity model and it is found that the number of passengers between stations does not grow with the decrease in the distance, thus deviating from the power-law behavior.
Spatiotemporal distributions of population in Seoul: joint influence of ridership and accessibility of the subway system
This study sheds light on the interplay of a public transportation system and land use, which is of relevance to planners and policymakers wishing to develop neighborhoods in support of sustainable modes.
A Three-Layer Model for Studying Metro Network Dynamics
A three-layer model, consisting of a rail layer, a train layer, and a passenger layer, is proposed to describe the structure and operation of a metro system, which permits assessment of the operational effectiveness of metro systems, which helps the metro operators to improve the performance and reduce the cost.
Emergence of Criticality in the Transportation Passenger Flow: Scaling and Renormalization in the Seoul Bus System
This work considers the criticality of the urban transportation system entailed in the massive smart card data on the Seoul transportation network and demonstrates that such ideas of physics as scaling and renormalization can be applied successfully to social phenomena exemplified by the passenger flow.

Hub-Periphery Hierarchy in Bus Transportation Networks: Gini Coefficients and the Seoul Bus System
It is revealed that the hub type evolves according to the controlled growth process while the peripheral one, displaying a number of new constructions as well as sudden closings of bus stops, is not described by growth dynamics.
Examining the effect of land-use function complementarity on intra-urban spatial interactions using metro smart card records
Three types of land-use function complementarity indices according to the spatiotemporal characteristics of human mobility are proposed and could be used for predicting spatial flow and trip distribution and also could be considered as factors in researches about transportation and land- use planning.
Spatiotemporal behaviors of the ridership of a public transportation system during an epidemic outbreak: case of MERS in Seoul
The spatial correlation function of the ridership changes is observed to follow a power law, sharing the same exponent as the spatial relaxation of the response function, which offers a useful tool for understanding responses of public transportation system to epidemic or accidental disasters.
Ranking Station Importance With Human Mobility Patterns Using Subway Network Datasets
A novel ranking method of station importance (SIRank) by utilizing human mobility patterns and improved PageRank algorithm is proposed, which demonstrates that the hit ratio in SIRank reaches 60% in the top five stations, which is much higher than that of ranking by a weighted mixed index and ranking by node degree approaches.


Modeling the world-wide airport network
A new model is proposed that explains the behavior of the world-wide airport network in terms of the geo-political constraints that affect the growth of the airport network and hypothesizes that in other infrastructures, critical locations might not coincide with highly-connected hubs.
Emergence of skew distributions in controlled growth processes.
This work derives the evolution equation for the size distribution of elements in an evolving system, where each element can grow, divide into two, and produce new elements, to obtain such skew distributions as power-law, log-normal, and Weibull distributions, depending on the growth or division and production.
How skew distributions emerge in evolving systems
A master equation approach gives a unified description of those three types of skew distribution observed in a variety of systems, providing physical derivation of them and disclosing how they are related.

This work first maps each router to its geographical location using two different state-of-the-art tools, then studies the relationship between router location and population density; between geographic distance and link density; and between the size and geographic extent of ASes.
Crossover from scale-free to spatial networks
A simple model which combines both preferential attachment and distance selection characterized by a typical finite "interaction range" shows that if the total length is fixed, the optimal network which minimizes both thetotal length and the diameter lies in between the scale-free and spatial networks.
The architecture of complex weighted networks.
This work studies the scientific collaboration network and the world-wide air-transportation network, which are representative examples of social and large infrastructure systems, respectively, and defines appropriate metrics combining weighted and topological observables that enable it to characterize the complex statistical properties and heterogeneity of the actual strength of edges and vertices.
Discriminating between the Weibull and log‐normal distributions
The asymptotic distribution of the logarithm of the maximized likelihood ratio has been obtained and it is observed that the asymPTotic distribution is independent of the unknown parameters.
