“…On the other hand, the samples made from waste plastics possess a higher water percentage of absorption resistance of 5% than those made from cement whose highest percentage of water absorption resistance is 0.9%. Consequently, while waste plastic-bound paving stones cannot completely replace the use of cement cement-bound stones, they can still be used for pavements expected to carry light traffic ways, rural roads, or unimportant roads, walkways, and due to their high percentage of water absorption resistance, it will be suitable for use flood-prone and high water table areas [13,14].…”

Portland cement remains the major binder used in the construction of concrete pavements, interlocking stones, and many other aspects of construction, and this implies a high dependence on the commodity thus making it scares and expensive and hence the need to explore other alternatives. This research compares the use of waste plastics and Portland cement for the production of paving stones. In this study, three cases were considered, each case having a study sample and a control sample. Case 1, case 2, and case 3 had mix ratios of (in order of, binder to sand to granite) 1:1:1, 1:1:1.5, and 1:1.5:2.5 respectively, of which the controls were made using Portland cement as the binder and the samples were made with waste plastic as the binder. The comparison was done using compressive strength and water absorption resistance values of the controls and the sample. The results showed that paving stones made from Portland cement have better compressive strength in all cases compared to the samples, the highest compressive strength obtained from the controls was 45N/mm2 while that of the sample was 25N/mm2, however, the study sample showed the highest water absorption resistance percentage of 5%, when compared to the control samples which had as low as 0.8%. This infers that paving stones made from melted waste plastics may not be as strong as those made from Portland cement can be used for roads expected to carry lighter traffic, and are also very suitable for areas of high water table or areas prone to flooding. The samples in this research were made locally and were limited to the three mix ratios mentioned. Further research can be done using a mechanized method to produce the samples, also partial replacement of cement with waste plastic may hence the strength of the paving stone.

“…The most recent developments in detection and communication technology have significantly improved the capacity to gather real-time traffic data [28,29]. This data helps intelligent transportation system (ITS) applications in traffic signal control and enables traffic engineers at traffic management centers (TMCs) to react proactively to traffic condition changes to reduce traffic congestion and boost throughput.…”

In junction traffic operations, vehicle delay is one of the most essential performance measures of effectiveness. It allows traffic engineers to assess the performance of a traffic system component or the efficacy of a system-wide control plan. Real-time applications such as adaptive signal control, congestion management, and dynamic traffic assignment often use this technology. Obtaining real-time data on intersection performance, such as control delay, may be time-consuming and labor-intensive. This study presents a new approach for estimating network-level real-time delay from passive traffic counting. Total Travel Delay Estimation Technique (TTD) is proposed for signalized intersection delays that can be computed by examining real-time data from arrival and departure detectors upstream and downstream of a junction. The proposed estimation method mathematically manipulated equations that relate the input-output model and vehicle O-D data acquired from the Automatic Turning Movement Identification System (ATMIS). The developed methods utilize the obtained real-time traffic detection system as input data. The proposed methods are applied for three cases: simple, semi-generalized, and generalized networks, where any of them can be used as a building TTD estimation block for the whole actual network. Results from the TTD were compared to VISSIM output, and a statistical test was conducted under varying traffic conditions (low, medium, high, and saturated). The findings show that the proposed methodology can yield stable and reliable results in various traffic volumes and turning movement conditions. Future field implementation studies for the suggested methods are recommended to evaluate the model's reliability and efficacy in real-time traffic scenarios.

“…Mobile robots have gained widespread application in fields such as industrial production, transportation, and the service industry, becoming a focal point in current technological research [1,2]. Path planning refers to the process by which robots navigate autonomously based on environmental perception through their sensors [3,4], and its algorithm design and optimization cannot be separated from the effective deployment of sensors [5]. The autonomous navigation of mobile robots is an intelligent system encompassing technologies such as environmental perception, path planning, and navigation positioning [6,7].…”

In the domain of mobile robotic navigation, the real-time generation of low-cost, executable reference trajectories is crucial. This paper propounds an innovative path planning strategy, termed Dynamic Bridging Rapidly Exploring Random Tree (DBR-RRT), which endeavors to enable safe and expedited path navigation. Initially, a heuristic discrimination method is engaged in the path search phase, whereby the issue of sluggish search velocity is tackled by evaluating whether sampled points reside at “bridging locations” within a free space, and by assessing the spatial–geometric relationships between proximate obstacles and auxiliary points. Subsequently, by leveraging extended speed, additional sampling points are generated in the vicinity of existing points to augment the search’s efficacy. Ultimately, the path is optimized and pruned by synthesizing the local curvature of the sampling points and the proximity to obstacles, assigning varied priorities to nodes, thus ensuring that the path’s quality and smoothness is upheld.
