Thesis (MBA)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: The study involved a detail empirical investigation into the different road studs in use on South Africa’s national road network and how they performed on the network under different road conditions in order to establish which road stud, under what conditions, offers best value for money in terms of life-cycle cost for the South African National Roads Agency Limited. These main questions were asked: What is the most cost-effective/value-for-money stud option for SANRAL to choose for each of the specified road categories? Under

Abstract:

Chevron pavement markings have seen rising interest in the United States as a means to reduce speeds at high-speed locations and improve safety performance. In Atlanta, there are two freeway-to-freeway ramps where chevron markings are being used. A previous study analyzed before-and-after speed data at these ramps and found only a modest reduction on overall vehicle speeds. However, a cursory crash analysis indicated that the ramps had crash reductions of over 60%, suggesting that safety benefits exist even though vehicle speeds are not significantly affected. This research aims to evaluat

L'estimation de la pose (position et l'attitude) en temps réel est une fonction clé pour les véhicules autonomes routiers. Cette thèse vise à étudier des systèmes de localisation pour ces véhicules en utilisant des capteurs automobiles à faible coût. Trois types de capteurs sont considérés : des capteurs à l'estime qui existent déjà dans les automobiles modernes, des récepteurs GNSS mono-fréquence avec antenne patch et une caméra de détection de la voie regardant vers l’avant. Les cartes très précises sont également des composants clés pour la navigation des véhicules autonomes. Dans ce travai

Abstract:

Per prevedere la visibilità della segnaletica orizzontale sono stati sviluppati diversi modelli sia negli Stati Uniti (DETECT / PCDETECT) che in Europa (CIE 73 / COST 331). Il livello di visibilità viene definito come il rapporto tra il contrasto presente tra la luminanza del segnale e quella della superfice stradale, e un contrasto soglia. Per calcolare quest’ultimo (Cth), tutti questi modelli si riferiscono ai dati di Blackwell o al modello di Adrian. Tuttavia, essi sono in grado di valutare il Cth per oggetti di forma circolare, mentre la segnaletica orizzontale ha una forma poligonale. Pe

The objective of this dissertation is to develop a Multi-Camera Lane Departure Warning (MCLDW) system and a framework to evaluate it. A Lane Departure Warning (LDW) system is a safety feature that is included in a few luxury automobiles. Using a single camera, it performs the task of informing the driver if a lane change is imminent. The core component of an LDW system is a lane detector, whose objective is to find lane markers on the road. Therefore, we start this dissertation by explaining the requirements of an ideal lane detector, and then present several algorithmic implementations that m

Public roads without road markings, especially roads carrying high traffic volumes, would lead to chaos and accidents resulting in injuries and loss of life. The road authorities need to ensure that all signage is well maintained and conforms to the Southern African Development Community Road Traffic Signs Manuals (SADC RTSM) (1999) and the South African Road Traffic Signs Manuals (SARTSM) (1999). The most important aspect of road markings is that they must be retroreflective. The minimum RL for white and yellow road markings is 100 mcd/m2/lx and 70 mcd/m2/lx respectively (SADC RTSM, 1999).

Abstract:

Current New Zealand guidelines encourage the installation of painted centrelines and edgelines on rural roads. Though it is known that speed is directly proportional to both accident likelihood and severity, the effect of pavement markings on speed is unclear. This study looked at the effect of pavement markings (centrelines and edgelines) on speed. The study method involved speed surveys at matched pairs, to compare sites with an edgeline and centreline, to centreline only sites, and to compare a further set of centreline-only sites to sites with no markings. Sites within pairs were all on

The results show that a reduction or an increase in lane width, the presence of posted speed signage or a change in the posted speed limit, horizontal curves, and centre line marking influence driver speed

碩士<br>逢甲大學<br>運輸與物流學系<br>107<br>The most common road markings in traffic engineering are closely related to the use of passers-by. The markings have functions such as regulating traffic, warnings, prohibitions and instructions. They are closely related to driving safety, and Taiwan is often humid and rainy in the monsoon climate. It is often useful for passers-by to go through the marking line to cause slipping, resulting in loss of life and property. When similar traffic accidents occur too often, we must check whether such traffic facilities are designed correctly. The "marking line" is divi

碩士<br>國立成功大學<br>測量及空間資訊學系碩博士班<br>96<br>Recently, the issue of integrating airborne LiDAR and aerial photogrammetry has been in academic and industrial spotlight, because both technologies have their unique characteristics respectively and some advantages of airborne LiDAR can compensate for shortcomings of aerial photogrammetry, and vice versa. An absolute prerequisite for combining both data sets is to establish a common reference frame. The main objective of this study is to utilize the point features in LiDAR point cloud and aerial image to determine external orientation of aerial images de

碩士<br>國立高雄應用科技大學<br>模具系碩士在職專班<br>105<br>At present, hot-melt road markings is used most in Taiwan. According to Traffic Engineering Code of the Ministry of Transportation and Communications, the general road marking anti-skid coefficient needs to be higher than 45 BPN (British pendulum number), with the material hot melt resin, and add glass beads, to achieve reflective effect. Although it can increase the visibility at night, it also cause scooter slipping when it is raining. This study is aimed at changing the existing pattern of road marking, design with drainage function and increase the a

Abstract:

The Indiana Department of Transportation (INDOT) manages and maintains over 3,000 miles of interstates across the state. Assessing lane marking quality is an important part of agency asset tracking and typically occurs annually. The current process requires agency staff to travel the road and collect representative measurements. This is quite challenging for high volume multi-lane facilities. Furthermore, it does not scale well to the additional 5,200 centerline miles of non-interstate routes. <div><br></div><div>Modern vehicles now have technology on them called “Lane Keep Assist” or LKA, tha
