title: Design and application of sewage treatment process in expressway service area
abstract: In order to improve the efficiency, impact resistance and purification effect of sewage treatment in service areas, the composition and quantity of sewage water quality in expressway service areas were studied. A highway service area in Yunnan Province uses a combined process for sewage treatment, and the scale has been reached 4000m3/d. The specific process is "multi point water inlet A/O process denitrification sand filter phosphorus removal filter chlorine dioxide disinfection activated carbon filter".The actual effluent quality meets the"Discharge standard of pollutants for municipal wastewater treatment plant" (GB18918 2002) And the first class standard meets the requirements of "The reuse of urban recycling water Water quality standard for urban miscellaneous water consumption" (GB/T18920 2002) The engineering practice proves that it is completely feasible to use this combined process to treat sewage in the highway service area, which can be used for reference and reference by similar projects.

title: Hydrologic performance of bioretention in an expressway service area.
abstract: Bioretention can be an effective measure for stormwater treatment. However, there is a lack of systematic analysis of the impact of bioretention design parameters on hydrologic performance. Herein, SWMM and RECARGA models were applied to generate the typical annual rainfall runoff and simulate the water balance of the bioretention system in an expressway service area. The purpose of the investigation was to identify key design parameters for the bioretention system and delineate the priorities in developing the design. Results showed that the average groundwater recharge ratios for bioretention basins with and without an underdrain were 58.29% and 92.27% respectively, the average overflow ratios were 4.13% and 4.19% the average evapotranspiration ratios were 4.48% and 4.47% and the average outflow ratio for bioretention with an underdrain was 33.94% The ratio of the bioretention area to drainage area, and the saturated infiltration rates of planting soil and native soil were the main factors influencing water balance, while the underdrain diameter and gravel layer depth exerted little effect. Based on the impact analysis, multivariate nonlinear regression models of runoff reduction rate for two types of bioretention basin were established, which both exhibited high determination coefficients and acceptable Nash Sutcliffe coefficients.

title: Economic feasibility of ground source heat pump system deployed in expressway service area
abstract: In an attempt to mitigate the reliance on fossil fuels as main power sources for expressway service areas in South Korea, a ground sourced heat pump (GSHP) is explored as an alternative power source, especially for high oil consuming service areas, and its economic feasibility is evaluated using three investment financing metrics: Payback Period, Net Present Value (NPV) and Internal Rate of Return (IRR) Fuel consumption and energy load data collected from 174 (out of 197) expressway service areas are analyzed to characterize their energy profile, and along with the energy per unit price, 20 simulation targets (service areas) with high oil consumption are selected to maximize the potential benefits of the GSHP system. Rather than a conventional peak load design concept, a base load (an energy load corresponding to 65% of total annual energy) is introduced for an optimal system design and operation. A pilot test building is constructed to verify the coefficient of performance (COP) of a GSHP system applicable to the target service areas. The results show that the payback period of GSHP systems is less than three years, regardless of energy loads and deployment options (new and retrofit) In addition, positive net present values and higher internal return rates suggest the proposed GSHP systems should be a viable option to save operation costs while maintaining higher energy efficiency. Finally, the potential greenhouse gas reductions of GSHP systems relative to oil furnace/air conditioning systems are calculated over the selected service areas.

title: Management of expressway service area based on integrated optimization
abstract: In view of the imperfect construction and the widespread loss on domestic expressway service areas, simply relying on the capital and human resources investment cannot improve the economic benefits efficiently. The M Expressway service area is one of the most representative service areas in the Shanghai Nanjing region. In this optimization project, we optimized the main revenue item and allocated parking spaces based on profit contributions, finally optimized the parking layout. With profit as the core, we linked the scattered business in the service area and achieved the goal of sequential optimization and overall optimization.

title: LID Facility Layout and Hydrologic Impact Simulation in an Expressway Service Area
abstract: In order to solve the problem of rainwater discharge in expressway service areas, low impact development (LID) facilities are arranged systematically in an expressway service area in China. A storm rainwater management model is applied to simulate the hydrologic process so as to analyze the influence of a bioretention area on rainfall runoff regulation under three LID situations: separate bioretention, bioretention and permeable pavement in series, and bioretention, permeable pavement, and grass swales in series. Based on the results, increasing the ratio of bioretention area to drainage area increases the average values of runoff reduction rate, runoff peak reduction rate, and runoff peak delay time under five types of rainfall. The results indicate that permeable pavement can significantly reduce the hydraulic load of bioretention while grass swales have little effect. Under different rainfall levels, the runoff reduction rate of the LID service area increases by 16.16 68.41% the runoff peak reduction rate increases by 49.31 59.07% and the runoff peak delay time increases by up to 326 min compared with a traditional service area.
