Selection Of

The selection of an optimal urban public transport system is prepared by a feeding-back planning process based on systems analysis. The decision situations are presented graphically, they define a plausible area of value judgements and insert into the figure indifference lines for each pair of alternative systems. The scheduling problem is handled by applying utility profile theory and zero–one optimization technique. By means of a particular formulation of variables and constraints, horizontal and vertical interdependencies between investment alternatives can be integrated.

The article presents basic rules for creating schematic maps of public transport systems. It is focused on the creation of map keys and their symbols and on utilising different styles of depicting public transport networks. It describes schematic map creation process and emphasizes factors, which influence selection of means of expression. The subsequent section of the article deals with the method for evaluating the quality of schematic maps. The method examines user-friendliness of a psychological method using a structured interview. The article also presents schematic maps as a useful method for cartographic presentation of research results in geography of transport.

Overall Performance

Robustness studies on integrated urban public transport networks have attracted growing attention in recent years due to the significant influence on the overall performance of urban transport system. In this paper, topological properties and robustness of a bus–subway coupled network in Beijing, composed of both bus and subway networks as well as their interactions, are analyzed. Three new models depicting cascading failure processes on the coupled network are proposed based on an existing binary influence modeling approach. Simulation results show that the proposed models are more accurate than the existing method in reflecting actual passenger flow redistribution in the cascading failure process. Moreover, the traffic load influence between nodes also plays a vital role in the robustness of the network. The proposed models and derived results can be utilized to improve the robustness of integrated urban public transport systems in traffic planning.

The present article discusses economic issues related to the design of optimal regulatory contracts on the example of the urban public transport industry. It highlights the importance of the design of efficient regulatory contracts in the context of changes facing the urban transportation industry in the European Union. Furthermore, it provides an overview of the main issues put forward in economic literature related to the design of regulatory contracts. It discusses several problems relevant in this context such as informational asymmetries, transaction costs, and regulatory capture. It also comments on a selection of views presented in economic literature dealing with these issues. Finally, the article presents the regulatory framework, contractual practices and characteristics of the French urban public transport industry. France is well known for its long standing tradition of contracting between the State and the private sector in transportation. The analysis of the French example may help to prove useful insights in this regard.

Tourist Center

Identification of the role of the waterbus system in the development of tourism in a large coastal city – a tourist center of international importance. Cartographic materials, qualitative and quantitative data on the waterbus system, spatial development and tourist traffic were used. Quantitative temporal and spatial analyses were conducted, including GIS analyses. Service of the tourist traffic is the dominant function of the waterbus in Gdańsk. This is determined by three categories of factors: (i) the seasonal nature of the system and a low level of integration with the public transport system; (ii) low potential demand for transport services due to the fact that most of the stops are far away from large residential or work centers; (iii) proximity of most of the city’s main tourist attractions to the stops. The obtained results are helpful in programming the development of public transport systems, especially in large tourist coastal cities. The conditions of spatial development are of key importance for shaping the dominant function of the waterbus.

Speed Up

There is a large number of tools for the simulation of traffic and routes in public transport systems. These use different simulation models (macroscopic, microscopic, and mesoscopic). Unfortunately, these simulation tools are limited when simulating a complete public transport system, which includes all its buses and routes (up to 270 for the London Underground). The processing times for these type of simulations increase in an unmanageable way since all the relevant variables that are required to simulate consistently and reliably the system behavior must be included. In this paper, we present a new simulation model for public transport routes’ simulation called Masivo. It runs the public transport stops’ operations in OpenCL work items concurrently, using a multi-core high performance platform. The performance results of Masivo show a speed-up factor of 10.2 compared with the simulator model running with one compute unit and a speed-up factor of 278 times faster than the validation simulator. The real-time factor achieved was 3050 times faster than the 10 h simulated duration, for a public transport system of 300 stops, 2400 buses, and 456,997 passengers.

Last Mile

Bicycle Sharing Systems (BSSs) are exponentially increasing in the urban mobility sector. They are traditionally conceived as a last-mile complement to the public transport system. In this paper, we demonstrate that BSSs can be seen as a public transport system in their own right. To do so, we build a mathematical framework for the classification of BSS trips. Using trajectory information, we create the trip index, which characterizes the intrinsic purpose of the use of BSS as transport or leisure. The construction of the trip index required a specific analysis of the BSS shortest path, which cannot be directly calculated from the topology of the network given that cyclists can find shortcuts through traffic lights, pedestrian crossings, etc. to reduce the overall traveled distance. Adding a layer of complication to the problem, these shortcuts have a non-trivial existence in terms of being intermittent, or short lived. We applied the proposed methodology to empirical data from BiciMAD, the public BSS in Madrid (Spain). The obtained results show that the trip index correctly determines transport and leisure categories, which exhibit distinct statistical and operational features. Finally, we inferred the underlying BSS public transport network and show the fundamental trajectories traveled by users. Based on this analysis, we conclude that 90.60% of BiciMAD’s use fall in the category of transport, which demonstrates our first statement.
