Replacing worn or damaged parts implies high material costs and financial expense for public tram transportation services, especially for the imported units and that is why it is preferable to recondition them, taking into consideration the safety requirements. In this paper, ISIM initiatives and achievements are presented in the field of cost reduction and maintenance during operation of trams, by introduction in the operation process of worn parts, within the safety limits. Aspects are presented regarding the possibilities for reconditioning and repair of parts with a circular geometry (e.g. wheel bands, axles, drum brakes). Some of these are being applied and implemented. Also, innovative ideas are presented for increasing the performance of equipment used for reconditioning.

This study proposes a framework to analyze public discourse in Twitter to understand the impacts of COVID-19 on transport modes and mobility behavior. It also identifies reopening challenges and potential reopening strategies that are discussed by the public. First, the study collects 15,776 tweets that relate to personal opinions on transportation services posted between May 15 and June 15, 2020. Next, it applies text mining and topic modeling techniques to the tweets to determine the prominent themes, terms, and topics in those discussions to understand public feelings, behavior, and broader sentiments about the changes brought about by COVID-19 on transportation systems. Results reveal that people are avoiding public transport and shifting to using private car, bicycle, or walking. Bicycle sales have increased remarkably but car sales have declined. Cycling and walking, telecommuting, and online schools are identified as possible solutions to COVID-19 mobility problems and to reduce car usage with an aim to tackle traffic congestion in the post-pandemic world. People appreciated government decisions for funding allocation to public transport, and asked for the reshaping, restoring, and safe reopening of transit systems. Protecting transit workers, riders, shop customers and staff, and office employees is identified as a crucial reopening challenge, whereas mask wearing, phased reopening, and social distancing are proposed as effective reopening strategies. This framework can be used as a tool by decision makers to enable a holistic understanding of public opinions on transportation services during COVID-19 and formulate policies for a safe reopening.

In recent times, there is an increase in the utilization of the ride-hail service (viz., mobile application-based shared service) by the younger generation due to tremendous changes in technology, extensive usage of smartphones, and perceived convenience during travelling. For evaluating ride-hail service further, it is necessary to understand the user perception towards the ride-hail service and public transportation system (viz., bus in this case) to efficiently plan the public transportation services. Hence, the present study analyzes user perception while making trips, using ride-hail service and public transport buses. A long stretch of 3.8 km has been selected in the Nagpur city for the study and the stretch attracts a good number of trips by ride-hailing and public transportation. To perform the analysis, a survey has been conducted in the stretch which includes an online survey (viz., based on the Google form) and an offline survey (viz., at selected bus stops on the route between university campus and shopping complex). A binary logit model has been developed to understand the user perception towards ride-hail service and to identify the significant contributing factors towards the preference of the ride-hail service over the public transport bus. From the model results, it has been noted that age, accessibility, waiting time, travel time, income, and travel cost of the trip are the most significant contributing factors that affect user decision for availing the ride-hail service. It has been concluded from the study that the inferences obtained would be useful in the direction of developing warrants for transport planners and policymakers to improve the service quality of public transport buses (viz., frequency and routes) in cities especially in the Indian context.

Increasing Trends

Bus priority routes (BPRs) promote public transport use in urban areas; however, their safety impacts are not sufficiently understood. Along with proven positive mobility effects, such systems may lead to crash increases. This study examines the safety impacts of BPRs, which have been introduced on busy urban roads in three major Israeli cities—Tel Aviv, Jerusalem and Haifa. Crash changes associated with BPR implementation are estimated using after–before or cross-section evaluations, with comparison-groups. The findings show that BPR implementation is generally associated with increasing trends in various crash types and, particularly, in pedestrian crashes at junctions. Yet, the results differ depending on BPR configurations. Center lane BPRs are found to be safer than curbside BPRs. The best safety level is observed when a center lane BPR is adjacent to a single lane for all-purpose traffic. Local public transport planners should be aware of possible negative implications of BPRs for urban traffic safety. Negative safety impacts can be moderated by a wider use of safety-related measures, as demonstrated in BPRs’ operation in Haifa. Further research is needed to delve into the reasons for the negative safety impacts of BPRs under Israeli conditions relative to the positive impacts reported in other countries.

Mobility Solution

The continuing growth of urbanisation poses a real threat to the operation of transportation services in large metropolitan areas around the world. As a response, several initiatives that promote public transport and active travelling have emerged in the last few years. Mobility as a Service (MaaS) is one such initiative with the main goal being the provision of a holistic urban mobility solution through a single interface, the MaaS operator. The successful implementation of MaaS requires the support of a technology platform for travellers to fully benefit from the offered transport services. A central component of such a platform is a journey planner with the ability to provide trip options that efficiently integrate the different modes included in a MaaS scheme. This paper presents a heuristic that implements a scenario-based journey planner for users of MaaS. The proposed heuristic provides routes composed of different modes including private cars, public transport, bike-sharing, car-sharing and ride-hailing. The methodological approach for the generation of journeys is explained and its implementation using a microservices architecture is presented. The implemented system was trialled in two European cities and the analysis of user satisfaction results reveal good overall performance.

Nowadays, the age of most transport facilities in Russian Federation is estimated in many decades. Consequently, there is an urgent need for periodic surveys and monitoring of the state of each structure, its individual structural elements. The main purpose of these measures is to maintain the high performance indicators of the transport structure, the achievement of which is impossible without examination, analysis and evaluation of parts of the structure that are in the aquatic environment and, as a consequence, the occurrence and development of various types and degrees of defects and damages. The most important conditions for ensuring uninterrupted and safe traffic along the bridges of vehicles and pedestrians are: the normative load-carrying capacity of the structure; required clearance of the roadway and sidewalks; compliance with traffic safety requirements for bridges; observance of characteristics and maintenance of the bridge capacity for the period of ice drift and high water; timely performance of work on the care, maintenance and repair of the elements of the bridge. Technically sound structures and their reliability can be ensured if all the parameters of the road category structure and the requirements of regulatory documents are met. The work presents the survey materials of the bridge. Classification of defects by group and class of danger. The results of determining the carrying capacity on the basis of the survey are given.

Elderly Users

Due to the rapid increase in population and the change in age structure toward the elderly, the phenomenon of societal ageing is being witnessed in many countries. The elderly travel less than the adult population due to decreasing mobility with an increasing age. In this study, we aimed to analyze the expectations and satisfaction of public transport users in Thailand using traditional importance performance analysis (IPA), gap analysis, and IPA integrated with competitor performance. We aimed to explain the differences in the analysis results produced by the three methods. The data were obtained from surveying 2250 elderly and 450 non-elderly adults. This study presents guidelines for improving the public transport service quality in Thailand to meet user needs. The results of this research showed that each approach provides its own distinctive aspects and theoretical differences, which lead to different interpretations. The results from the three approaches showed that equipment that increases safety for public transportation service users is an important factor for all elderly passengers that must be improved. Public transportation services in different regions should be developed to provide more reliable and regular services.

Vulnerable Road Users

Every year approximately 1.35 million people die as a consequence of road accidents. Almost 50% of road fatalities are vulnerable road users (VRUs). This research reviews the history of traffic safety for VRUs, presents an interesting insight into the statistics and evaluates the current legislation in Europe for pedestrians, cyclists, children on bicycle-mounted seats and motorcyclists in terms of impact situations and applied criteria. This enabled the author to have a better perspective on how the VRUs’ safety is currently verified. Furthermore, the VRU safety requirements are contrasted with the author’s research, which is mainly focused on VRU’s head biomechanics and kinematics. Finally, a new coherent method is presented, which encompasses the sub-groups of VRUs and proposes some improvements to both the regulations as well as technical countermeasures to mitigate the injuries during an impact. This study highlights the importance of numerical methods, which can serve as a powerful tool to study VRUs’ head injuries and kinematics.
