“…Wastewater including restaurant sewage, domestic sewage, toilet sewage, was mainly from the toll station, service area, maintenance working area and management center [3]. Many studies indicated that highway wastewater is close to domestic wastewater [3][4][5][6]. Water quality of a day monitored in highway service area in Jilin Province was taken as an example (Fig.…”

The present status about wastewater treatment at highway affiliated facilities of China including characteristics of wastewater and treatment technology, the effect of wastewater treatment were investigated. It was found that wastewater quantity was mainly depending on traffic volume entering the service area. Integrated process of wastewater treatment was the main technology used at highway affiliated facilities. 80.4% of the total devices discharge the water which can meet the “Integrated Wastewater Discharge Standard (8978-1996)”. About 69.6% of water was discharged into the road ditches, 22.2% was used for greening and flushing toilet. 3.9% of water evaporated naturally, 2.7% of water was discharged into the river, and only 1.6% was used for agricultural irrigation. The results provided scientific reference for the construction, improvement and management of wastewater treatment device at highway affiliated facilities by relevant departments in the future.

“…The verification results indicate that the speed predictor has fine accuracy, and the energy consumption of the proposed strategy is 9.85% less than that of the rule‐based strategy. Fu et al [ 36 ] proposed a torque distribution strategy based on the logic threshold to develop the control rules for the vehicle power system. The optimal working area of the engine and drive motor in different operating modes can be found by the strategy, and the torque demanded is reasonably distributed.…”

The eco‐driving strategy is of great significance in driving cost for plug‐in hybrid electric vehicles in driving trips, especially at signalized intersections. To address the issue of further energy saving, this study proposes an ecological approach and departure‐driving strategy by using syncretic learning with trapezoidal collocation algorithm. First, a syncretic learning‐based speed predictor is built by merging back propagation neural networks and radial basis function neural networks. Second, the syncretic learning‐based speed predictor and trapezoidal collocation algorithm are combined to optimize the speed trajectory. Third, the torque between the engine and the motor is distributed by the dynamic programming algorithm. Then, model predictive control optimizes torque output in the control time domain. Finally, the driving interval optimization method is designed to avoid mixed‐integer programming problems and redundant constraints, which make vehicles cross intersections without stopping. The numerical verification results show that the trapezoidal collocation algorithm with syncretic learning has more advantages than other methods in speed trajectory planning. Compared with the original trajectory, the driving time through the intersection is reduced and the total driving cost is lowered by 19.82%. Validation results confirm the effectiveness of the proposed strategy in energy consumption management at signalized intersections.
