Problem. Currently, there exist two main types of service on public transport routes – headway-based and timetable-based. They differ by the frequency of service at the stops and by the information available for passengers. The required frequency of service significantly affects transport operator costs and passenger travel time which, in turn, influences the cost for a passenger. One of the ways to reduce costs for both parties of the transportation process is to make a reasonable choice of the type of service or switch between the types during the day depending on the passenger flow volume. Goal. In the paper, to justify the choice of between the types of service, the cost of public transport vehicles operation and the losses of passenger travel times are taken into account. Methodology. The developed way of making a choice about the type of service allows increasing the efficiency of urban public transport due to reducing the passenger waiting time by switching from the headway-based service in rush hours to timetable-based service in the periods of passenger flow volume decline. Results. The relationship allowing making a decision about the type of service on the route is developed. It allows to correctly introduce the type of service which will ensure the balance between the transport operator and passenger costs. Originality. The developed approach to make a decision on the type of service allows reducing the passenger waiting time by switching from headway-based service in rush hours to the timetable-based service in the periods of decline in passenger flow volume during the day. Practical value. The results of the research based on the survey data allowed estimating the numerical value of the headway at which it is expedient to switch to the timetable-based service.

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 Relationship

Background: Literature on the negative socio-economic and environmental externalities generated by informal public transport (IPT) in developing countries is vast, vibrant and growing fast. These externalities include but are not limited to noise, air and land pollution, accidents and, more importantly, a source of congestion (human and vehicular) because of poor driver behaviour. In this article, the research does not seek to reinstate these, but rather, it argues that poor driver behaviour is a dependent variable to some regulatory policy stimuli. Yet, an extensive literature survey has shown that the driver behaviour and urban transport regulation linkage remain little explored.Objective: The purpose of this article was to unpack the relationship between informal public transport driver behaviour and the prevailing regulatory framework.Method: Based on a case study of Harare, Zimbabwe, the researcher adopted a mixed-methods paradigm and interrogated the prevailing urban public transport regulatory regimes and applied professional judgement, oral interviews backed by some quantitative data and relate these to obtaining IPT driver behavioural characteristics.Results: Poor driver behaviour exhibited by IPT were generated, exacerbated and or eased by the prevailing regulatory policy. This is well depicted through an IPT driver behaviour and regulation loop reinforcing diagram.Conclusion: Following this argument, the article cautions policy makers and urban managers alike that direct approaches and interventions when trying to regulate IPT poor driver behaviour and its secondary negative effects will be futile as long as the regulatory policy remains the same. Failure to recognise and connect the dots between IPT driver behaviour and policy partly explains why globally, the IPT sector has proved difficult in prohibiting, restructuring or even formalising it.

Urban public transport is an effective way to solve urban traffic problems and promote sustainable development of urban traffic. A scientific operation scheduling system has an important guiding significance for optimizing the configuration of urban public transport capacity resources, improving the level of operation organization and management, and providing for the sustainability of the transportation system. According to the inhomogeneous distribution of passenger flow along transit lines, this study develops a combinational scheduling model in which the enterprise supplies zonal service based on regular service. The objective function minimizes the sum of passenger travel cost and operation cost, and the simulated annealing algorithm is designed to solve the optimization model. This paper abstracts an ideal example by taking a real-world case of Bus Line 131 in Lanzhou, China. The numerical example is used to verify the validity of the model and algorithm. Results show that the combinational operation scheme can effectively satisfy passengers’ demand and reduce the total cost by 7.03% in comparison with the regular operation system. The optimal combinational system with the lowest total cost can increase the vehicle load factor and improve the utilization ratio.

The Relationship

Urban public transport ensures a high level of service for its users. Despite the challenges of comprehensiveness of the measurement of the level of transport service, the one of the most important unit assessment is in-vehicle crowding level. Excessive crowding level of the vehicle compartment causes passengers feeling uncomfortable during trip. Consequently, the crowding level is a factor, should be rationing. Assessment of in-vehicle crowding level observing using different indicators which have variation in units of measurement, descriptive properties, circumstances of apply, etc. Simultaneously, it makes it harder to assess and compare conditions of public transit according to occupancy rate, via dissimilar measures of its value, as well during the observation, as well as the address the challenges of urban public transport organization. In view of the above-mentioned, formalization of the relationship between the crowding indicators in urban public transport is a pressing task that needs to be addressed. The research presents the relationship between these in-vehicle crowding level: the passengers density per sq. m of the vehicle’s floor intended for standing passengers (passenger density) The floor area of the vehicle intended for single standing passengers; load factor which is defined as the ratio of the number of passengers in the cabin of the vehicle to its capacity; load factor is defined as the ratio of the number of passengers in the cabin of the vehicle to the number of seats. The relationship between considering indicators of occupancy rates of vehicles have been established. Its value is entirely determined via dependencies of the ratio of seats in the passenger capacity of vehicles and the passenger density at which its was found. Further research is focused on the application of the proposed dependencies in solving the problems of rationing the public transit crowding level and assessing the influence of the occupancy rate on the passenger’s route choice decisions. Keywords: public transit, passenger transportation, vehicle capacity, in-vehicle crowding level, load factor.
