Abstract
Passenger ropeways are a promising alternative for the development of public transport infrastructure in large cities. However, the construction of ropeways has a rather high cost and requires taking into account a significant number of restrictions associated with the features of the existing urban development and the placement of urban infrastructure. The main objective of this research is to develop optimization models that minimize the total cost of modular intermediate towers of a discretely variable height and a rope system due to the optimal placement and selection of the height of these towers, taking into account the features of the surface topography and urban development. The proposed modular principle for the construction of intermediate towers also enables the cost of construction to be further reduced. As a specific example, the design of a ropeway in the city of Bryansk, which has a complex terrain, is considered. The developed models are conveniently used at the initial stage of the design of the ropeway to compare the cost of various options for the location of the ropeway route in order to reduce the risk of error when choosing the least expensive option. The calculation results can serve as a guide for a preliminary assessment of the number and height of intermediate towers, their installation locations on the ground and the characteristics of the cable system.
Highlights
At present, the aerial ropeway is considered as a promising alternative to the development of transport infrastructure in large cities and megacities [1, 2], as well as in territorial clusters [3, 4]

5 Optimal Design Results Analysis Calculations were made for a number of possible variants of the aerial passenger ropeway using the computer program ‘‘Optimization of the ropeway lines with unified towers’’ [27]
Summary
The aerial ropeway is considered as a promising alternative to the development of transport infrastructure in large cities and megacities [1, 2], as well as in territorial clusters (for example, tourist or recreational) [3, 4]. Mobile aerial rope systems placed on wheeled or tracked chassis of high carrying capacity and cross-country are promising [12] They solve the problem of rapid deployment of the transport system, even in conditions of unequipped and inaccessible territories
