Is traffic police SERVQUAL assessment different among drivers in terms of experience?

Designing tailored services is critical to enhancing client satisfaction for private and public services such as road traffic. Among the factors associated with car accidents are traffic violations of established rules and regulations. Indeed, driving skills and practice have become crucial in a complex and dynamic road environment. The study’s objective was to advise traffic department managers on how to customize their service for drivers regarding their experience. A questionnaire assessing their expectations and perceived performance with regard to six traffic service quality dimensions, namely tangibility, reliability, promptitude, responsiveness, assurance, and empathy, was self-administered to 886 motorists chosen using a simple random sampling technique in the Philippines and South Africa. Data collected were analyzed using ANOVA and Post Hoc Tuckey HSD. Results indicate that less experienced drivers had a better appreciation of traffic service quality provided by traffic departments and officers. Therefore, more focus should be placed on experienced drivers to raise their level of satisfaction.

Who's Got My Back? Measuring the Adoption of an Internet-wide BGP RTBH Service

Distributed Denial-of-Service (DDoS) attacks continue to threaten the availability of Internet-based services. While countermeasures exist to decrease the impact of these attacks, not all operators have the resources or knowledge to deploy them. Alternatively, anti-DDoS services such as DDoS clearing houses and blackholing have emerged. Unwanted Traffic Removal Service (UTRS), being one of the oldest community-based anti-DDoS services, has become a global free collaborative service that aims at mitigating major DDoS attacks through the Border Gateway Protocol (BGP). Once the BGP session with UTRS is established, UTRS members can advertise part of the prefixes belonging to their AS to UTRS. UTRS will forward them to all other participants, who, in turn, should start blocking traffic to the advertised IP addresses. In this paper, we develop and evaluate a methodology to automatically detect UTRS participation in the wild. To this end, we deploy a measurement infrastructure and devise a methodology to detect UTRS-based traffic blocking. Using this methodology, we conducted a longitudinal analysis of UTRS participants over ten weeks. Our results show that at any point in time, there were 562 participants, including multihomed, stub, transit, and IXP ASes. Moreover, we surveyed 245 network operators to understand why they would (not) join UTRS. Results show that threat and coping appraisal significantly influence the intention to participate in UTRS.

RT-CBCH: Real-Time VPN Traffic Service Identification Based on Sampled Data in High-Speed Networks

Virtual Private Network (VPN) technology can bypass censorship and access geographically locked services. Some harmful information may be hidden in VPN traffic and circumvent the surveillance systems, bringing a significant challenge to network security. Considering the increasing richness of service types in VPN traffic, identifying traffic service facilitates further targeting harmful VPN traffic. Therefore, VPN traffic service identification is critical in network management. The existing identification methods use complete traffic for analysis. However, massive data analysis in high-speed networks consumes enormous resources, limiting the real-time processing of traffic identification. This paper proposes a real-time VPN traffic service identification method named RT-CBCH. We construct features that are still available after sampling and design a fast traffic processing structure based on Counting Bloom Filter and Chained Hash Table (CBCH). Experimental results validate the real-time capability, stability and accuracy of our method. At the sampling ratio of 1/256, it takes only 23.63 seconds to process the mixed traffic of 900-second traffic generated on a 10 Gbps link and our collected V2Ray traffic, which is increasingly common in VPN traffic. Under different sampling ratios, the identification results remain respectable, with an overall accuracy of about 90% for application service and over 99% for V2Ray proxy service. Furthermore, comparisons with similar work illustrate the high accuracy and low resource consumption of RT-CBCH. Experimental results show that our method can stably implement real-time VPN traffic service identification from sampled data in high-speed networks.

Smart traffic routing and service allocation strategy to reduce water consumption in data centers through power reduction

Influence of Building Layout and Weather Conditions on Air Traffic Services

I Gusti Ngurah Rai International Airport is one of the busiest airports in Indonesia that serves a variety of flights, ranging from scheduled, unscheduled, cargo, and military, to recreational flights. All flights are regulated by the Air Traffic Controller which is divided into two units, namely the Aerodrome Control Tower and Approach Control Surveillance. The Aerodrome Control Tower has the responsibility of regulating flight traffic in the "vicinity of aerodrome" area. From the tower, ATC must be able to monitor all movements of flight operations in the area of responsibility. However, at the I Gusti Ngurah Rai Airport tower, several things can affect ATC's view in monitoring the movement of flight operations, namely airport buildings that block several parking stands, dark night conditions in the maneuvering area, and extreme weather. Of course, these problems will also affect the performance of ATC in providing flight traffic services. In addition, it can cause doubts in ATC in making decisions for aircraft that are being handled. This research aims to analyze the problem of ATC's limited view in monitoring the movement of flight operations in its area of responsibility. The research method used is qualitative with data collection techniques in the form of observation, literature study, interviews, and documentation. The development of Advanced Surface Movement Guidance and Control System that can monitor the movement of flight operations in various conditions can be one solution to the problem. In addition, the installation of CCTV in several areas that are not visible from the tower can also assist ATC in monitoring the movement of flight operations in the area. The results of this study are expected to assist ATC in monitoring the movement of flight operations both in dark night conditions and extreme weather. The author also hopes that the results of this study can be useful in improving organized and efficient flight traffic services at I Gusti Ngurah Rai International Airport.

The author encourages relevant authorities to consider and implement the proposed solutions to establish a more efficient, effective, safe, and comfortable air traffic control environment at Tarakan APP, ultimately benefiting air navigation services.

Development and Balance Evaluation for Land Use and Transport Interaction Using Node‐Place Model and Data Envelopment Analysis

To meet the evolving demands of land use and transport interaction (LUTI) assessment within China’s national territory spatial planning (NTSP) system, this paper introduces the level of development (LoD) and the level of matching (LoM) evaluation models, based on the traffic facility and land use factors. The LoD model, founded on the modified node‐place model, provides a comprehensive assessment of the traffic facility and land use development scales. Conversely, the LoM model, grounded in data envelopment analysis methods, evaluates the relative relationship between transport services and the travel demand generated by land use. The integrated use of LoD and LoM can both reflect the development scale and matching status between traffic services and travel activities, which are crucial contents in the planning works, especially within the NTSP framework. The proposed models are tested in the city of Guangzhou, and the LoD values exhibit peaks in central urban zones, suburban towns, and areas adjacent to railway transit, with a decline observed in rural farmland and ecological regions. In contrast, the LoM distribution performs a distinct pattern, highlighting numerous underperforming areas with congestion or idle problems in urban centers, alongside well‐coordinated regions showcasing a balance between traffic facilities and land uses in rural regions. Furthermore, the LoM scores revealed frequent instances of facility crowding in urban regions and intensive occurrences of facility idleness in rural areas. By marking regions with low LoD scores, the LoD model finds suitable application in determining the urban development border, essential for restricting land development and preserving farmland and ecological areas. Meanwhile, LoM aids in improving urban renewal efforts by assessing and optimizing the balance between intensive land uses and limited traffic facilities. Validated against the existing metrics, the combined use of LoD and LoM efficiently captures the most details of the LUTI process at the lowest computational cost.

Estimation of Road Service Quality Using the Two‐Fluid Model Considering the Resilience of Traffic Flow

In an urban road network, the ability of the traffic flow itself to alleviate congestion caused by external disruptions is overlooked. This study applied the two‐fluid model to simulate mesoscopic traffic flow, focusing on the resilience of urban road networks under normal disturbances. Three resilience indices—plasticity, transition of elasticity, and elasticity—were introduced based on the failure deformation process of rigid materials. These indices were used to modify the two‐fluid model’s parameters, considering the effects of bus operations and temporary roadblocks on traffic flow and service quality. A hidden Markov model (HMM) was employed to predict service quality transitions (distinction, merit, and pass), with validation using dynamic bayonet traffic data from Xuancheng and video recordings from Xi’an, China. The results confirmed that resilience varies significantly across different times and locations, with peak hours and dense urban areas exhibiting lower resilience and higher susceptibility to disruptions. Bus queuing was found to degrade service quality, and rainstorms had a more severe impact than construction zones. The study can aid in the development of management efficiency of urban road networks.
