This purpose of this paper is to evaluate the experiences of public-private partnerships (PPPs) in China's urban rail development, investigates the critical factors impacting on the project viability and derives lessons for future urban rail PPP projects in China and elsewhere.
A case study of the Beijing Metro Line 4 project was adopted as the main research method with semi-structured interviews with senior practitioners and experienced academics as the primary data collection instrument. Qualitative data were collected and subjected to content analysis.
The case study provides six critical factors which are required to facilitate PPP urban rail development: streamlined approval process; robust tendering; strong leadership within the public procuring authority; effective organisational structure and the private sector innovation; commensurate charging approach and government subsidising scheme; and appropriate risk allocation. The research shows that the potential to directly re-apply the Beijing Metro Line 4 model to future urban rail development is limited, but lessons for future urban rail PPPs can still be drawn from the study.
The paper serves as an illustration to public procuring authorities and potential private investors on how to structure and manage urban rail PPPs.
The research presents an original investigation of China’s first urban rail PPP, the Beijing Metro Line 4 project and assesses the applicability of the Beijing model to future PPP projects in urban rail development.

Purpose – The chapter studies methods of integrating the connection between land use and traffic surrounding rail transit stations. It offers guidance to urban planners about how to arrange transfer facilities scientifically and promote more efficient use of land nearby.
Methodology – The chapter describes studies of station type, station positioning, recommended building floor area ratio (FAR), traffic connection and land use functional demand for five stations on No. 2 Metro Line in Nanjing, determining the traffic connections and layout for the land use surrounding the five stations.
Findings – This study of the integrated connection between land use and transport surrounding rail transit stations will act as a guide to help arrange the building of essential transfer facilities scientifically and help cities to make better use of the scarce amount of urban land available for development. This study also shows that the transport system plays an important part in adjusting the functional layout of land use surrounding rail transit stations.
Social implications – The results of this study will be particularly significant in the integration of urban planning management and transport management. Furthermore, the coordinated interaction between land-use planning, traffic planning and urban design will benefit Chinese cities as they continue to grow throughout the 21st century and beyond.

Traffic congestion and disorderly development of land will affect the development of cities. How to make efficient use of urban land is a major issue for cities. Based on this, the problems existing in the planning and construction of urban rail transit in our country were analyzed. The method of rail transit network layout, as well as the site size, site selection and spacing optimization methods were analyzed. The combinatorial network layout planning of Metro Line in a city was studied. According to the layout of rail transit stations, a layout optimization model was proposed. Three basic network layouts were used to lay down the subway lines in this city, and the site size, spacing and intersection points were planned. The effective utilization rate of urban land was increased, and people's travel time was saved, so as to provide a new idea for the layout of rail transit

Light Rail Transit (LRT) systems have emerged as an attractive form of public transport both in industrialised as well as developing countries. This paper reviews the implementation mechanism of LRT projects proured by private finance, through Build Operate Transfer (BOT) type concession contracts. A case study approach is used to model an actual LRT project. The case study analysis shows that the uncertainty factor could be converted to monetary terms and the process would enhance ability of the decision makers to have a better understanding of the consequences of risks.

Regenerative braking is an efficient energy saving technology in urban rail system, in which the recovery energy from braking trains is collected by some equipments and released to accelerating trains when needed. However, the high cost and low lifetime of storage devices prevent the widespread use of this technology. The purpose of this paper is to conduct thorough cost-benefit analysis to facilitate China’s urban rail companies to make decisions on the use of such technology.
To evaluate the benefit from regenerative energy storage, the authors formulate an improved integrated scheduling and speed control model to calculate the net energy consumption associated with different energy recovery rates and then define the benefit as the amount of energy saving arising from the usage of storage equipments. With the frequent charge/discharge operations on storage equipments, the energy recovery rate generally decreases which lowers the benefit, but the maintenance cost increases. By trading-off benefit and cost, the authors derive the optimal scrapping time, the maximum profit and the profitability condition for storage devices.
Simulation studies based on the Beijing Metro Yizhuang Line of China are given. The results show that compared with the current timetable and speed profile, the integrated scheduling and speed control approach with energy recovery rate of 0.5 can reduce the net energy consumption by 12.69 per cent; the net energy consumption can be well approximated as a linear function of energy recovery rate; and the maximum profit and the optimal scrapping time on regenerative energy storage devices are both positively related to the electricity price. The allowance proportion and the number of service trains such that busy lines with higher electricity price or allowance proportion have advantages to use the regenerative energy storage devices.
In this work, a linear energy recovery rate and a linear maintenance cost are used in the cost-benefit analysis process. In future research, the more accurate expressions on energy recovery rate and maintenance cost should be considered if more data on recovery rate and maintenance cost can be gathered.
The main values of this paper are to develop the integrated optimization approaches for train scheduling and speed control and, on this basis, make thorough cost-benefit analysis for regenerative energy storage to improve the operations management of urban rail transit.

Beijing rail transit can actively control the density of rail transit passenger flow, ensure travel facilities and provide a safe and comfortable riding atmosphere for rail transit passengers during the epidemic. The purpose of this paper is to efficiently monitor the flow of rail passengers, the first method is to regulate the flow of passengers by means of a coordinated connection between the stations of the railway line; the second method is to objectively distribute the inbound traffic quotas between stations to achieve the aim of accurate and reasonable control according to the actual number of people entering the station.
This paper analyzes the rules of rail transit passenger flow and updates the passenger flow prediction model in time according to the characteristics of passenger flow during the epidemic to solve the above-mentioned problems. Big data system analysis restores and refines the time and space distribution of the finely expected passenger flow and the train service plan of each route. Get information on the passenger travel chain from arriving, boarding, transferring, getting off and leaving, as well as the full load rate of each train.
A series of digital flow control models, based on the time and space composition of passengers on trains with congested sections, has been designed and developed to scientifically calculate the number of passengers entering the station and provide an operational basis for operating companies to accurately control flow.
This study can analyze the section where the highest full load occurs, the composition of passengers in this section and when and where passengers board the train, based on the measured train full load rate data. Then, this paper combines the full load rate control index to perform reverse deduction to calculate the inbound volume time-sharing indicators of each station and redistribute the time-sharing indicators for each station according to the actual situation of the inbound volume of each line during the epidemic. Finally, form the specified full load rate index digital time-sharing passenger flow control scheme.
