The annual increasing use of motorized vehicles requires improvements in infrastructure to support the reliability of urban transport systems in Surakarta City. The Government of Surakarta City has attempted to improve the infrastructure of the Gilingan Viaduct by creating an underpass. The traffic performance of the model developed is analysed using Indonesian Capacity Manual 1997 (IHCM 1997). The result shows that the development of the Gilingan Underpass has a potential to improve the performance of Jenderal Ahmad Yani road and the performance of the Balapan and Cengklik Intersections. The change of public transport routes of goods (freight) and people to Jenderal Ahmad Yani road has an opportunity to reduce acute congestion at the Joglo Intersection and decrease the accident rate in Monginsidi road.

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.

Using Data

In recent years fare-free public transport (FFPT) found itself at the centre of attention of various groups, such as economists, transport engineers and local authorities, as well as those responsible for the organisation of urban transport. The FFPT is hoped to be the answer to contemporary transport-related problems within cities, problems which largely result from insensible proportions between trips carried out via personal mode of transportation and those completed by the means of public transport. This article reviews the motives and effects connected with the introduction to date of fare-free transport zones across the globe. It also presents, using data obtained in market research, the actual impact of a selective extension of the entitlement to free fares on the demand for urban transport services. The effects observed in other urban transport systems were then compared against those observed in relation to one, examined system. Analyses of observed FFPT implementation effects were then used to establish good and bad practices in the introduction of FFPT. The article also contains forecasts on the effect of the extension of entitlement to free fares and an increase in the public transport offer may have on the volume of demand for such services. The analyses have shown that an increase in the public transport offer (understood as an increase in the volume of vehicle-kilometres) would increase the demand for urban transport services more than the selective implementation of FFPT (assuming that the costs incurred by the local authorities remain unchanged).

Cilegon is one of the National Activity Centre (PKN) in Banten Province. As PKN, Cilegon generate movement from out of town towards Cilegon, either using AKAP/AKDP buses and urban transportation from the place of origin. Many AKAP/AKDP bus passengers fell in the shadow of the terminal, while the urban transport passengers from the outside get into the city of Cilegon and drop off passengers . The number of outer urban transport operating in Cilegon Cilegon City area adds to congestion in Jalan Sultan and Jalan Ahmad Yani Ageng Tirtayasa , especially at rush hour. Therefor, the Government of Cilegon Municipality then implement the construction of SeruniTerminal, officially put into operation on April 1, 2013. With the expected Seruni terminal buses no longer drop off passengers at the terminal shadow, and urban transport outside the city of Cilegon not get into town. Positivistic approach and methods used in this study is a quantitative method , as well as some analysis used : (1) the analysis of the characteristics of SeruniTerminal, (2) analysis of traffic volume in Seruni Terminal, (3) analysis of urban transport route network in Cilegon, and (4) policy analysis for development of The Seruni Terminal, is expected to answer the research question, namely : " the role of Seruni Terminal in the urban transport system in Cilegon Municipality? "The results obtained from this study is the lack of Seruni Terminal has a role in urban transport systems in Cilegon. To enhance the role, it’s can be done with urban transport route A.01 Cilegon-Anyer and Merak-Cilegon M.01 directed toward Seruni Terminal, and/or the addition of a new trajectory Cilegon-JLS. Therefor, Seruni Terminal is expected to increase the role of the movement in serving urban communities in Cilegon.

<p>Bogor Regency has an economic growth rate including the highest among cities and other districts around the Jakarta Capital Region. Regarding the condition of the vehicle population in Bogor district, the number of motorized vehicles in 2017 and 2018 experienced a growth of between 2% and 12%. In contrast to the growth rate of vehicles, the road growth rate is only 0.1% per year. Nurul Hidayah Mosque is located on Jalan Salabenda, the object of the author's research to find out how much influence the sound of motorized vehicles has on worship activities around the Nurul Hidayah mosque. In public transport car speed, motorcycle speed, and private car speed do not have a significant effect on the noise pollution produced. The noise level around the Nurul Hidayah Mosque, Jalan Salabenda Raya, Bogor Regency which has been measured the smallest is 56.4 dBA. This value exceeds the noise threshold of the Noise Level Standard Value for the Ministerial Decree, which is 55 dBA. So that it requires attention and cooperation from the government and the community to overcome the noise in the worship area. The calculation and analysis obtained is on the equation with the largest R Square value on the fourth day of the study, the third point (Sound Level Meter 3), with a contribution of 22.67%. Like the equation on the side, y = 73.251 + 0.004x<sub>1</sub>-0.311x<sub>2</sub>-0.003x<sub>3</sub>. The meaning of this equation is that if there is no decrease in the speed of motorbikes, private cars and public transport cars, the noise pollution level in SLM3 is 73,251 dBA. If there is an increase in the speed of public transport cars by 0.004, the decrease of motorbikes by 0.311, and an increase in the speed of private cars by 0.003, the noise pollution level will decrease by 0.31 dBA at SLM3.</p>

Regarding intermodal urban transport systems for passengers, there is no recognized standard for performance analysis. Detecting the weaknesses of such systems can allow managers to carry out more assertive, corrective actions and make them more attractive to users. The main objective of this article is to propose a model for evaluating the performance of intermodal travel for passengers in urban environments. The exploratory factor analysis was the method used to evaluate and classify the variables that constitute the proposed standard. The results show that the factors related to travel time, infrastructure and available information are the most important characteristics for the interviewed public. The operational performance analysis carried out in the Metropolitan Region of Recife, state of Pernambuco, Brazil, reveals the difficulties faced by the citizens while making an intermodal trip, which may be contributing to a reduction in the number of users of the passenger transport system.

Obvious Effect

This article has taken up an issue concerning the influence of the implementation of electromobility assumptions on reduction of air pollution in cities in terms of sustainable urban transport systems. The essential nature of the subject is confirmed by the following figures: transport is responsible for almost 25% of greenhouse gas emissions in Europe and is the main cause of air pollution in cities, almost 90% of city dwellers in the EU are exposed to levels of air pollutants deemed harmful by the WHO, and approximately 95% of vehicles on European roads still use fossil fuels. Therefore, the implemented transport policy, both in the international and domestic aspect of particular countries, is facing the need to significantly reduce the negative influence of transport on people and the environment. Electromobility has become one of the concepts that makes it possible to achieve this goal. Its main objective is to reduce emissions of harmful substances into the environment by deploying electric vehicles (EVs). Research conducted by the authors showed that public transport, apart from the obvious effect of decreased number of private vehicles and decreased congestion, can contribute to reduced air pollutant emissions and become a significant driver for the implementation of electromobility in cities. However, the achievement of this goal depends on taking appropriate actions not only in the transport branch but also in other sectors of economy. The following research methods were applied in the article: literature analysis, documentary method, case study, and mathematical methods. The research area was the city of Szczecin, Poland.

Transport Modes

Active transport modes play a key role in developing sustainable transport systems by making cities accessible, safe, inclusive, and green. In Latin America and the Caribbean, walking and cycling represent a large share of total trips, especially for low-income groups. But for them, the decision to travel by using active transport modes, especially walking, is not based on sustainability but affordability. Income disparities in the region are also reflected in pedestrian and cycling infrastructure, with poor neighborhoods lacking infrastructure of sufficient quality or size. Despite some successful experiences in the region, there is a lack of integration between transport modes, particularly public transport and cycling, which is crucial for improving the accessibility of low-income people, who usually live in peripheral areas, face long commutes, and require connecting infrastructure and services. The region has the opportunity to improve low-income groups access to livelihood opportunities and key services by developing infrastructure supporting nonmotorized transport, increasing citizen participation in planning, improving planning and regulation, and integrating active transport modes in urban transport systems, especially public transport.

The intensification of public transport in urban areas due to increased mobility at the regional and state levels, discrepancies between urban areas with the same population and the lack of statistics related to the efficiency and quality of public transport services are the main factors of our work. It is necessary to draw boundaries between the quality of services and the performance indicators of the public transport system. The quality of services is the subjective result of many intangible variables. The quality of service can be approached from four sides: from the point of view of the passenger, the performance of the vehicle, the specialized passenger transportation company, and the Government. Accessibility, comfort and convenience-these are the main indicators that should be evaluated by the population as having high ratings for the good quality of urban transport services. The tool used to collect the data is the preference survey. Keywords: service quality, public transport, evaluation, efficiency, methods, passenger, survey

Abstract A policy instrument promoting a free fare public transport policy (FFPT) has recently been put into practice in 66 municipalities across Poland. By contributing to the academic debate on the concept of FFPT (e.g. Kębłowski 2019), the main goal of this paper is to create a typology of the schemes where FFPT is in operation in Poland based on analyses of a geographical mapping of these projects. This study analyses how different municipalities are implementing the concept in order to define a typology of FFTP projects and to understand how the development landscape of the urban transport system is changing in the light of free fare transport policies, topics which are not fully covered in the academic literature. The findings confirm that there is a new dynamic in the development of urban transport systems and permit the identification of key characteristics of this trend. Besides the typology of implementation of FFPT, the study also presents an up-to-date inventory of FFPT projects with the key characteristic features of each system. Although the study does not provide specific recommendations regarding the introduction of a FFPT policy, it represents a good starting point for future and more detailed studies. Such studies are necessary in order to understand the role of FFPT not only in the context of the development of a given transport system, its impact on modal split, and travel behaviour, but also to uncover the different politics which lie behind them.
