• Data for meta-analyses may be biased by evaluation quality and journal quality. • We explored this in the context of effectiveness of physical road safety measures. • We combined CMF Clearinghouse (1000 + evaluations) and 8 journal ranking lists. • Most rankings showed that the better journal ranking, the better evaluation ranking. • The finding is critical with regards to predatory journals impacts on meta-analyses. Meta-analyses are an important source of road safety evidence. However, their source data may be biased by both evaluation quality and journal quality. This motivated us to explore the link, focusing on the effectiveness of physical road safety measures. We collected and combined two kinds of datasets: evaluation quality of research (seven samples) and journal quality (eight ranking lists). In the end, only the CMF Clearinghouse dataset of more than 1000 evaluations could be used. Despite some inconsistencies, six of eight rankings showed the expected positive relationship: the better journal ranking, the better evaluation ranking (and vice versa). This calls for the attention of authors and readers, as well as meta-analysts, particularly in the context of predatory journals and their potential impacts on the quality of road safety meta-analyses.

The improvement of public transportation service quality is highly influenced by the competence, performance, and behavior of drivers, who serve as the frontline of service delivery. The Public Transport Driver Certification Training (SPAU) is conducted to enhance professionalism, driving safety, and service ethics; however, its effectiveness in the field needs to be evaluated comprehensively. This study aims to assess the effectiveness of SPAU training on drivers’ performance and behavior, as well as its impact on passenger satisfaction, using an integrated analytical approach. The research employs a quantitative approach with data triangulation from drivers, their direct supervisors, and passengers. Analyses are conducted using Structural Equation Modeling (SEM) to examine causal relationships among variables, Importance Performance Analysis (IPA) to identify service attributes requiring priority improvement, and the Customer Satisfaction Index (CSI) to measure overall passenger satisfaction. The results indicate that competencies acquired from the training significantly influence improvements in drivers’ performance and behavior, which in turn positively affect passenger satisfaction. IPA analysis reveals several service attributes that still require improvement, while the CSI score shows that overall passenger satisfaction falls within a good category. These findings underscore the importance of strengthening the curriculum, providing post-certification guidance, and implementing continuous monitoring to ensure the sustainability of the training’s impact on public transportation service quality.

Penelitian ini menyoroti peran strategis konektivitas lintas negara dalam mendukung integrasi sosial-ekonomi dan pertumbuhan kota di wilayah perbatasan, dengan studi kasus rute darat Singkawang–Kuching. Fokus utama adalah analisis preferensi moda transportasi berdasarkan faktor biaya dan waktu. Menggunakan pendekatan kuantitatif dan metode stated preference dalam delapan skenario atribut (tarif, waktu tempuh, dan waktu akses), data dikumpulkan dari 91 responden. Analisis dilakukan menggunakan model logit binomial dan regresi linier berbasis generalized cost . Hasil menunjukkan bahwa biaya perjalanan menjadi faktor utama dalam pemilihan Bus Damri, sedangkan kenyamanan dan mobilitas lebih mempengaruhi pengguna angkutan sewa. Model memiliki koefisien determinasi R² sebesar 0,652, yang mengindikasikan bahwa 65,2% variasi dalam pemilihan moda dapat dijelaskan oleh perbandingan biaya total. Temuan ini menegaskan pentingnya menyediakan transportasi lintas batas yang efisien dan terjangkau untuk mendukung daya saing kota perbatasan seperti Singkawang. Studi ini memberikan dasar bagi perumusan kebijakan transportasi berbasis data, pengembangan infrastruktur seperti terminal internasional, serta penguatan konektivitas sebagai bagian dari strategi pembangunan kawasan perbatasan dalam konteks integrasi regional ASEAN.

We present an overview of wildlife-vehicle collision (WVC) liability covering 36 European countries. We reviewed approaches to WVC liability which are currently in effect across Europe and their potential consequences for WVC reporting. To obtain relevant information, we conducted a survey, including a web-based questionnaire. We retrieved answers to questions related to human fatalities from WVC, the existence of WVC databases, roadkill data systems and recommendation for drivers in the event of WVC. In 19 countries, no one is liable when a motorized vehicle collides with a wild animal. In the remaining countries, road managers or road owners may be liable as well as drivers or hunters, either consistently or under certain conditions. Liability can, in some countries, be changed after a legal assessment. Human fatalities due to WVCs have been reported in 27 countries, with approximately 90 deaths annually across European roads. The number of injured people and estimates of socio-economic losses were not possible to obtain at a European level as many countries lack reliable databases. We discuss how existing WVC liability across countries provoke some actors to transfer liability to another actor or avoid reporting these incidents altogether. WVC underreporting in certain national databases is one of the consequences of the existing WVC liability rules in the given countries. This fact reduces the potential to identify hotspots and define appropriate mitigation measures. In conclusion, we propose several procedures for modifying WVC liability that could enhance wildlife protection and road safety.

The intention of the research project of the Technology Agency of the Czech Republic is to propose a classification scale for the evaluation of the noise level of pavement layers based on long-term repeated measurements using the Close Proximity Method (CPX). With regard to the other variable parameters (skid resistance, surface unevenness, bearing capacity and defects) that are monitored in the Czech Republic, a five-point scale was also proposed. The scale was tested on the busiest motorway section in the Czech Republic between Prague and Brno, which has been modernized in recent years. The first sections were put into operation in 2014 and the last in 2021. The evaluation of the results of the CPX measurements carried out in regular one-year cycles from 2013 to the present allowed to test the proposed classification scale. This paper will present the results obtained from the modernization of the highway and the proposed classification scale.

Road Administrations (RAs) implement Building Information Modelling (BIM) through pilot projects developed for new or reconstructed structures. Each model is processed with respect to BIM standards and practices valid at the time of its creation. Consequently, models are incompatible and cannot be interconnected to create a combined model of the managed network or even its selected parts. Existing structures are often not included in the BIM effort until some major repair is planned. In addition, RAs usually store data on fixed and variable parameters of structures in relational databases. This results in a situation in which a relatively small number of structures are included in mutually incompatible models and data regarding the majority of structures is contained in relational databases. It creates a heterogeneous data environment for RAs. The goals of the paper are as follows: to analyse the described problem, to propose a method of model unification models, a method of creation of simplified compatible information models using data on existing structures stored in relational databases and a method of storing data at the level of the managed network, to support RA asset management systems which can be treated as a dynamic part of BIM.
