Photoluminescent paints for road marking have been evaluated through laboratory measurements and visibility computations. The luminance decay in the dark was measured after constant excitation during at least six hours. To study the effect of night-time lighting conditions, luminance was also measured under a constant low illumination simulating moon and light pollution, and a periodic lighting simulating automotive traffic. Measurements were also carried out on luminescent road markings applied in a full scale mock up. Then, possible uses and limits of photoluminescent road markings were investigated through visibility computations based on the COST 331 model. Findings suggest that luminescent road markings could strengthen the visual guidance of drivers on the road with traffic by increasing the visibility distance beyond the range of the headlamps during the first few hours of the night, but it depends on the night-time illumination level.

This paper presents the development of a road lane detection algorithm using image processing techniques. This algorithm is developed based on dynamic videos, which are recorded using on-board cameras installed in vehicles for Malaysian highway conditions. The recorded videos are dynamic scenes of the background and the foreground, in which the detection of the objects, presence on the road area such as vehicles and road signs are more challenging caused by interference from background elements such as buildings, trees, road dividers and other related elements or objects. Thus, this algorithm aims to detect the road lanes for three significant parameter operations; vanishing point detection, road width measurements, and Region of Interest (ROI) of the road area, for detection purposes. The techniques used in the algorithm are image enhancement and edges extraction by Sobel filter, and the main technique for lane detection is a Hough Transform. The performance of the algorithm is tested and validated by using three videos of highway scenes in Malaysia with normal weather conditions, raining and a night-time scene, and an additional scene of a sunny rural road area. The video frame rate is 30fps with dimensions of 720p (1280x720) HD pixels. In the final achievement analysis, the test result shows a true positive rate, a TP lane detection  average rate of 0.925 and the capability to be used in the final application implementation.

Safety of people and traffic police on road and the provision of prompt and appropriate treatment of injured persons in road accident are urgent concerns. The nine recommendations accordingly made are 1) Considering anyone who informs about or brings to the hospitals the accident victims as innocent until proved otherwise, 2) Annual payment by all vehicle owners (as per the cost of vehicles) to generate treatment fund for any road accident injured patients in the free general (not paying or private or extended health service) outdoor or emergency clinics or ward of the public hospitals irrespective of anyone’ fault in the accident (insurance or other agencies may be assigned to handle the amount deposited and reimbursement of the payments to the hospitals), 3) Implementation of helmet wearing by motorcycle riders and pillion riders in motorcycles, 4) Stricter fine for hazardous traffic offenses, 5) Drivers of the larger vehicles should not automatically be held responsible for any accidents involving other smaller vehicles (to prevent smaller vehicles and motorcycles to drive recklessly), 6) Drivers should not be just held responsible to bear health expenses of injured patients (which is much more than the compensation required in the event of death of injured persons); this is to encourage drivers to take injured persons immediately to hospitals and prevent inclination to allow their deaths indirectly or directly; the drivers should be proportionately fined or punished as per the traffic regulations if they are found to be negligent, 7) Safe and visible platform for the traffic police to stay on the road, 8) Provision of cost-effective respirators for traffic police and traffic supervisors, and 9) Compensation for occupational hazards to the traffic police and field traffic supervisors by distributing to them adequate proportion (e.g. one-third to one-half) of the fund collected by stricter fine paid for the hazardous traffic offences. Provision of various allowances, including for hazards, and benefits is a common practice in the country. Compensation for the occupational hazards of the traffic police provides incentives to and motivates them to remain vigilant about hazardous traffic offenses day and night everywhere and, thus, is essential for the safety of the people.

An experiment was conducted in the road district of Kuopio in the winters of 1992–1993 and 1993–1994 in which the use of salt in winter maintenance on rural main roads was reduced to 1 to 2 T/road kilometer from the approximately 10 T of salt that typically had been used per road kilometer in similar conditions in recent years. On the experimental roads, salting was replaced by sanding. The cost of winter maintenance on the experimental roads increased by 20 percent on average, and the increase was higher on roads with higher traffic volumes. Slippery conditions due to ice and snow on the road surface were twice as frequent (30 to 40 percent of the time) on the experimental roads as on the control roads in the neighboring road district. There were 27 injury accidents on the experimental roads in the first winter and 25 in the second. This was about the same as the average of the five previous winters. Because the accident trend on other roads in the same time was decreasing, it was concluded that the experiment increased the number of injury accidents by approximately 20 percent on most experimental road sections. Reduced salting decreased the sodium and chloride concentrations in the needles of roadside pine trees. There were also indications of decreased sodium and chloride concentrations in groundwater. Three quarters of the population in the area was pleased with the experiment.

The costs of construction and the future maintenance of expressways and motorways have a significant impact on the choice of technologies for their construction. The subject of the article is the analysis of the costs of construction and maintenance of rigid (concrete) and flexible (asphalt mixtures) pavements in Poland. The construction technologies and maintenance scenarios in service were analysed for selected pavement constructions of rigid and flexible motorways and expressways. The costs of construction and maintenance of these pavements in national conditions were determined. The fourth quarter of 2015 was adopted as the initial price level. On the basis of the analysis of the costs of construction and maintenance of the analysed structures, the advantage of rigid constructions made of cement concrete was demonstrated, especially in the aspect of the surface maintenance. The cost assessment was carried out for 30 years of exploitation. The concrete pavements on the road network in Poland have been used for over 20 years. They are present both on low-class roads and on the highest-class roads, i.e. motorways and expressways.

There have been growing concerns involving the penetration of Electric Vehicles (EVs) due to the time required by its battery to attain full charge. Interests in EVs had recently experienced a dramatic turn down due to mileage limitation on full battery charge amidst the cost of purchase, but most notably due to the absence of quick chargers that can keep the vehicle on the road within few minutes of arriving at the charging station. Researchers had proposed different charging schemes such as level II ac charging, dc charging, and in some cases, wireless charging schemes that later appear to be inefficient. The use of dynamic or simply road-way powered electric vehicles was also proposed in the literature. However, the proposed cycloconverter-based circuit was simulated in Simulink, and the results obtained proved that the rate of charge increased when compared to the conventional EV charging circuit. Also, the focus is on battery charging technology and battery modeling for application in an electric vehicle

We explored the attitudes of Brazilians towards different methods to deal with boar taint in pork (surgical castration without pain control, SC; surgical castration with pain control, SC+PC; immunocastration, IC; raising entire males, EM). Two surveys (Sv1, n = 441 and Sv2, n = 768) containing closed and open questions were conducted. Nearly 70% of Sv1 and Sv2 participants were unaware that meat of entire males may have boar taint and that SC is widely used in pig production in Brazil. In Sv1, acceptability of SC+PC (63%) and IC (53%) was greater than of SC (15%). In Sv2, acceptability of IC (55%) and EM (52%) was greater than of SC (18%). Open-ended responses indicated that participants objected to inflicting pain to pigs to attain a production goal, and were concerned with organoleptic traits and risks of exogenous residues in pork. Participants’ views regarding the potential increases in the cost of meat due to adoption of alternative methods varied; some argued that avoiding pain justifies an increase in the price of pork and others that this would impact especially lower income citizens. Our findings indicate that participants opposed surgical castration without pain control, and supported alternative methods. However, the concern with potential risks of presence of residues in meat, expressed by a few participants, may need to be addressed among consumers.

Tree Method

Road departure is one of the main causes of single vehicle and frontal crashes. By implementing lateral support systems, a significant amount of these accidents can be avoided. Typical accidents are normally occurring due to unintentional lane departure where the driver drifts towards and across the line identifying the edge of the lane. The Lane Support Systems (LSS) uses cameras to “read” the lines on the road and alert the driver if the car is approaching the lines. Anyway, despite the assumed technology readiness, there is still much uncertainty regarding the needs of vision systems for “reading” the road and limited results are still available from in field testing. In such framework the paper presents an experimental test of LSS performance carried out in two lane rural roads with different geometric alignments and road marking conditions. LSS faults, in day light and dry pavement conditions, were detected on average in 2% of the road sections. A decision tree method was used to analyze the cause of the faults and the importance of the variable involved in the process. The fault probability increased in road sections with radius less than 200 m and in poor conditions of road marking.

Auto collisions have been taking a great many lives every year, dwarfing any savage ailments or cataclysmic events. Studies demonstrate that about 60% roadway crashes could be kept away from if the vehicle’s driver had been given cautioning at any rate one-half second before an impact. Human drivers experience the ill effects of recognition confinements on roadway crisis occasions, bringing about enormous postponement in spreading crisis alerts. Safety on the road is one of the key main impetuses behind the advancement, improvement, institutionalization and execution of ITS frameworks. Proposed system uses VANET Standards (VANET is a Mobile Ad-hoc Network (MANET)’s sibling which can organize its own communication model without any other infrastructure dependence). In this project, considering the different features and the cost, on a small scale a four- wheel vehicular robotic prototype has been designed that will follow the lane and avoid obstacles.

Pavement Thickness

There was a build-up of lumps of sand on the road, precisely Tambelang-Durjan. This build-up of sand chunks occurs because many of the piled sand hauling trucks that pass on the road is obstructed because the road section has been damaged (potholes) and is unfit for passage, resulting in obstruction of traffic flow. In addition, the width of the section is not in accordance with the technical requirements of the 2011 Government Regulation. Therefore, it requires a flexible pavement re-planning and a Cost Budget Plan for land transportation lines, so that motorist access is comfortable. Planning flexible pavement using Laston with a planning age of 10 years obtained flexible pavement thickness, namely 4 cm thick AC-WC, 6 cm thick AC-BC, and 40 cm of Upper Foundation Layers (LPA) with the estimated size of the Budget Plan The cost of the flexible pavement construction of Tambelang- Durjan of Sampang Regency with a length of 1,145 km in the amount of Rp 5,744,585,463.00Terjadi penumbukan bongkahan pasir urug tepatnya di ruas jalan Tambelangan-Durjan. Penumpukan bongkahan pasir ini terjadi karena banyak truk pengangkut bongkahan pasir urug tersebut yang melintas pada jalan itu terhambat karena ruas jalan mengalami kerusakan (berlubang) dan tidak layak dilalui, sehingga  yang mengakibatkan terhambatnya arus lalu lintas. Selain itu lebar ruas tidak sesuai dengan persyaratan teknis Peraturan Pemerintah tahun 2011. Oleh karena itu, memerlukan perencanaan ulang perkerasan lentur dan Rencana Anggaran Biaya untuk jalur transportasi darat supaya akses pengendara nyaman. Perencanaan perkerasan lentur menggunakan Laston dengan umur rencana 10 tahun didapatkan tebal perkerasan lentur yaitu AC-WC setebal 4 cm, AC-BC setebal 6 cm dan Lapis Pondasi Atas (LPA) setebal 40 cm dengan besar perkiraan Rencana Anggaran Biaya pembangunan perkerasan lentur ruas Tambelangan-Durjan Kabupaten Sampang sepanjang 1,145 km sebesar Rp 5.744.585.463,00.
