Research On The Operational Organization Scheme And Key Issues Of Mountain Tourism Tram Based On Benefit-Efficiency

Mountain Ridge tourist tram as a scenic traffic travel tool pays more attention to providing passengers with comfortable travel services and quality sightseeing experience.As the basis of the daily transportation organization of the tram system,a scientific and reasonable operation organization strategy is the key to improving the economic efficiency and transportation efficiency of the enterprise.Compared with the conventional city trams,the mountainous area tourist trams have the problems of overlapping long ramps and complex operating environments during operation.The optimization of the operating organization plan needs to consider the unique line conditions in the mountainous area,and the traditional optimization methods cannot meet the actual operating requirements.At the same time,the tourist tram is based on a semi-independent right-of-way,and the signal control at the intersection needs to take into account the operation of both trams and social vehicles to maximize the overall benefit.Therefore,it is important to evaluate and give feedback to adjust the operation organization scheme of tourist trams according to the characteristics of mountainous areas,to study the influence of long ramp section operation on tram passing capacity,and to optimize the tram timetable in combination with signal priority strategy to improve the business effectiveness-efficiency.This paper evaluates the operation organization scheme of tourist trams in mountainous areas from the dual perspectives of enterprise economic benefits and transportation efficiency and studies the key issues in the operation process.The specific research results are as follows:(1)Taking into account the economic efficiency and transportation efficiency of enterprises,the effectiveness-efficiency evaluation index system of operation and organization program is constructed from four dimensions of enterprise efficiency,transportation capacity,technical organization,and transportation service,and the calculation methods of each evaluation index are analyzed to refine and filter the index system.(2)With the comprehensive optimum of effectiveness-efficiency as the goal,an evaluation model of the effectiveness-efficiency of the tourist tram operation organization scheme in the mountainous area is constructed,and a projection feedback adjustment model is constructed with the evaluation results as the feedback basis.Taking Lijiang rail transit line 1 as an example,specific adjustment values are provided for the enterprise in terms of the number of train pairs,train travel speed,and train full load rate,and specific suggestions are provided for optimizing the operation organization scheme.(3)To study the effect of speed limit on tram passing capacity in long downhill sections.The tram traction calculation model and interval running time calculation model are constructed.Taking Lijiang rail transit line 1 as an example,four-speed limit schemes are designed,the interval running time and tram passing capacity under different schemes are calculated,and the train running diagram is completed.From the dual perspective of effectiveness-efficiency,it is suggested that the line adopt the speed limit scheme C to improve the passing capacity of the tram while maintaining a certain travel speed in order to meet the travel demand of passengers and improve the service level.(4)A tram timetable optimization method with different signal priority control strategies at different travel times is proposed.A tram timetable optimization model with integrated optimization of tram travel time and negative utility of signal priority strategy is constructed.Taking Lijiang rail transit line 1 as an example,the optimization results of this paper are compared with the original timetable scheme.The comprehensive optimization scheme of this paper better balances the conflict between objectives making the tram travel time as small as possible while greatly reducing the negative impact of signal priority strategy on social vehicles verifies the feasibility of the model and provides a theoretical reference for enterprises to design timetables.
