Evolution of Commercial Space near the Subway Stations of Community Type Based on Self-Organization Theory: A Case Study of Chengdu Wannianchang Subway Station

The subway stations of urban community type are not only main nodes in the urban traffic network, but also important places for peopled daily life. Widi the rapid development of urban metro and urban economy, the commercial space near tiie subway station has become the focus of urban planning and urban spatial development, and commercial self-oiganization pkys an important role in the development of commercial operations, commercial structures, and commercial scales, so how to make effective use of the inherent laws of the commercial space evolution, and further guide the rational development of community businesses needs more attention and research. This paper takes Chengdu Wannianchang Subway Station as an example to study the evolution stage, influencing factors, evolution characteristics and laws of the neatby commercial space. Moreover, suggestions were put forward such as coordinating competition and collaboration, optimizing space design and management, co-directional self-organization and heter-oiganizations, in order to provide a new reference for the healthy and ordedy development of the neighboring commefdal space near the subway stations of community type.

Energy management and coordination control of microgrid in elevated station of urban rail transit

The rapid development of urban rail transit brings convenience to the public,but its huge energy consumption problem cannot be ignored.A microgrid composed of photovoltaic power generation unit,regenerative braking energy feedback unit and battery energy storage unit is proposed,which provides green power for the station.In order to suppress the fluctuation of photovoltaic power generation and the intermittence of regenerative braking feedback energy,the energy management mode of microgrid is designed according to the illumination situation,braking energy feedback situation,battery state of charge and so on.In addition,a coordination control method based on virtual synchronous generator(VSG)is proposed to realize smooth switching among modes.Finally,the proposed energy management and coordination control method for elevated station microgrid is verified by Matlab/Simulink.The results show that the elevated station microgrid can operate safely and reliably under various energy management modes and realize smooth switching among modes.

Simultaneous optimization of transit network and public bicycle station network

The traditional manner to design public transportation system is to sequentially design the transit network and public bicycle network. A new public transportation system design problem that simultaneously considers both bus network design and public bicycle network design is proposed. The chemical reaction optimization(CRO) is designed to solve the problem. A shortcoming of CRO is that, when the two-molecule collisions take place, the molecules are randomly picked from the container.Hence, we improve CRO by employing different mating strategies. The computational results confirm the benefits of the mating strategies. Numerical experiments are conducted on the Sioux-Falls network. A comparison with the traditional sequential modeling framework indicates that the proposed approach has a better performance and is more robust. The practical applicability of the approach is proved by employing a real size network.

A Lattice Hydrodynamic Model for Trafc Flow Accounting for Driver Anticipation Efect of the Next-Nearest-Neighbor Site

In this paper, a new lattice hydrodynamic model is proposed by incorporating the driver anticipation effect of next-nearest-neighbor site. The linear stability analysis and nonlinear analysis show that the driver anticipation effect of next-nearest-neighbor site can enlarge the stable area of traffic flow. The space can be divided into three regions： stab/e, metastable, and unstable. Numerical simulation further illuminates that the driver anticipation effect of the next-neaxest-neighbor site can stabilize tramc flow in our modified lattice model, which is consistent with the analytical results.
