“…Therefore, they allow vehicles to adjust their direction of travel gradually. However, changes in the geometry of highway sections with an H curve often pose safety concerns (Sil, Nama,, Maji, & Maurya, 2020); (Ma, Yang, Wang, Xie, & Yang, 2020). Sharp turns have been known to cause driver instability (positioning themselves on a passing line), leading to a collision.…”

In general, the geometric planning of roads is done manually using drawing tools and mathematical techniques. When done manually, geometric design is complicated, time-consuming, and prone to errors. Therefore, this study will use AutoCAD Civil 3D®. This study aims to redesign the Trans Flores road because of the frequent accidents found on curves and climbs and the current road drops on the Trans Flores road. This study will use research methods using secondary data and qualitative research methods. When designing geometric roads using AutoCAD Civil 3D®, data from Google Maps, Google Earth, and Global Mapping is also required. This research will focus on the 3.5 km of road traffic starting from Sta 0+000 to Sta 3+500. The result of this study is that corners P1-P4 are planned with the type of Bend S-C-S. By using AutoCAD Civil 3D®, this research can be completed quickly and accurately.

“…Put simply, some researchers concentrate on enhancing the overall safety of an entire traffic network or a specific region [8,9], such as downtown New York City. Others address crash-related issues occurring on highway segments [10], on ramp/off ramp sections [11], weaving areas [12], and curved segments [13]. Additionally, efforts have been made to improve safety at intersections [14].…”

Traffic management systems play a vital role in ensuring safe and efficient transportation on roads. However, the use of advanced technologies in traffic management systems has introduced new safety challenges. Therefore, it is important to ensure the safety of these systems to prevent accidents and minimize their impact on road users. In this survey, we provide a comprehensive review of the literature on safety in traffic management systems. Specifically, we discuss the different safety issues that arise in traffic management systems, the current state of research on safety in these systems, and the techniques and methods proposed to ensure the safety of these systems. We also identify the limitations of the existing research and suggest future research directions.

“…To evaluate the effectiveness of friction treatments in improving traffic safety on curves, researchers have developed safety prediction models to quantify the relationship between curve crash frequency and curve geometry, pavement skid resistance, pavement characteristics, wet-weather conditions, and so forth ( 8 – 10 ). However, because of the scarcity of curve-related crash data, coupled with the large number of variables involved and the highly varied operating conditions under which crashes occur, statistical empirical equations have not been found satisfactory in establishing the safety effectiveness of different friction improvement treatments ( 11 , 12 ).…”

In friction management of horizontal-curve pavements, highway agencies develop treatment strategies for friction-deficient pavements mainly based on past experience or industry recommended practices. In the absence of an engineering procedure to evaluate the effectiveness of friction treatments, there is no sound basis for comparing the effectiveness of different treatment strategies. To overcome this limitation, this study explored a mechanistic approach to analyze friction treatments for a horizontal curve and compare the magnitudes of skid resistance improvement, reductions of skidding potential, and terminal polished skid resistance. This was achieved by applying the finite element simulation technique to calculate the tire–pavement skid resistance available and the safe vehicle speeds under a given set of design operating conditions. For illustration, five friction treatments for pavement curves were analyzed: resurfacing/overlay, high-friction resurfacing, longitudinal grooving, transverse grooving, and resurfacing/overlay plus raising of superelevation. The skid resistance, safe vehicle speed, and terminal skid resistance were determined for different wet-weather operating conditions. The operating conditions were defined by horizontal-curve geometric parameters, pavement surface properties, wheel load, geometric and structural properties of tire, and water film thickness. The effectiveness of an improvement treatment is evaluated by skid resistance improvement, skidding potential reduction, and terminal polished skid resistance. Two quantitative indicators were introduced for effectiveness evaluation: safe skid resistance margin ΔSN and safe vehicle speed margin ΔV. The proposed approach presents a quantitative engineering assessment procedure for highway agencies in the selection of a suitable treatment, and maintenance planning in their friction management of horizontal-curve pavements.
