“…Sugiyanto et al conducted a study on the effect of speed limit signs, and the results showed that the installation of speed limit signs on the highway is less effective to reduce vehicle speed. After the speed limit sign is installed, the vehicle speed is reduced only about 2.9 km/h to 5.5 km/h (5.6 to 10.1%) [37]. e speed limit studied in this paper is 80 km/h and 120 km/h.…”

Different vehicular speed limits may have an impact on the balance between safety and efficiency of travel on mountainous road corners associated with complex road conditions. Placing suitable speed limit warning signs does not merely effectively improve traffic safety but can also improve traffic efficiency. In this study, a global positioning system (GPS) terminal and Metrocount were used to collect vehicle speed data from more than 40 provincial-level curves in 8 provinces over the course of 1 year. Each road data collection time-period lasted approximately 8 hours. A descriptive statistics method was adopted by means of data screening and pretreatment. Additionally, both a velocity difference estimation model was established and a linear model of velocity differential estimation was constructed. Quantitative analysis was carried out on the safe speed, the driver’s expected speed, and the location of the speed limit warning signs. This demonstrated a positive correlation with the initial speed. When the difference in speed was greater than 15 km/h, a safety warning sign was required to limit the design speed to 80 km/h. A safety warning sign was also required when the corner radius was less than 300 m. The location of safety warning signs could be calculated based on the operating speed and taking driving safety and the visual range of drivers into consideration. The results can provide a theoretical reference for setting up appropriate safe speed limiting signs on road corners in mountainous areas.

“…According to the study, this led to a 41.9% decline in the number of road accidents, based on the number of road casualties at that time [22]. Recent studies, such as Aldred (2019) or Sugiyanto (2018), also take up this argument of increased safety at lower speeds in further analyses [23,24].…”

Responding to pressing problems arising from growing urban populations and mass motorization, municipalities need to take action. The resulting conditions include congested cities, poor air quality and quality of life. Providing contextual conditions and thereby increasing the amount of small electric vehicles could help reduce land use and improve air quality. Based on outcomes of expert interviews and an online survey, the status-quo of antecedences and barriers as well as potential measures for the implementation of small electric vehicles on a municipal level is outlined. To get an international and comprehensive view, experts from the USA, Asia and Europe participated. Results show that there are several obstacles that have to be overcome on local, national and international levels. For local policymakers especially, there is an array of measures available. The combination of push and pull measures is one key element. In this way, infrastructural changes, financial incentives, strategic implementations and soft measures to raise awareness could help the process of a market take-off immensely.

Angka kecelakaan lalu lintas semakin meningkat seiring dengan bertambahnya jumlah kendaraan khususnya sepeda motor dan mengendarai kendaraan melebihi batas kecepatan maksimum yang diijinkan atau speeding Sugiyanto & Malkhamah, 2018;Sugiyanto et al, 2019a Metrics and Evaluation, 2018). Tiga faktor penyebab kecelakaan lalu lintas yaitu manusia, kendaraan, dan lingkungan (Sugiyanto & Santi, 2015).…”

Vulnerable road users are pedestrians, un-motorized users, children, and elderly people. The problem of traffic safety is not only zero accidents, but also broader the creation of safe and comfortable environment for road users. Based on international understanding of traffic safety contained in the Global Road Safety Partnership (GRSP), traffic safety has involved elements of government, business, and civil society with the primary goal of raising awareness about the importance of safety and reducing mortality and injuries due to past accidents cross a sustainable basis, especially in developing and transition countries. To reduce the number of accidents can be done by carrying out and implementing the results of road safety audits, through forgiving roads that are able to minimize the severity of victims, roads that are able to explain intentions without communication (self-explaining road), and roads that are capable of creating compliance without warning (self-regulating road). One of the causes of traffic accidents is human error behavior and speed of vehicles which exceed the speed limits (speeding). One of the strategies to reduce the speeding by way speed restrictions of vehicle. Based on the analysis of the 85 th percentile and the probability of a pedestrian fatality rate when hit by a vehicle, the value of the speed limit on school hours at 30 km/h and 50 km/h for outside the school hours according to the terrain of the existing road with a flat and straight terrain. In Mayjen Sungkono Street (in front of Engineering Faculty Unsoed Blater Campus) along 150 m, the speed limit at 40 km/h. The results of road safety audit analysis are then implemented in the field by installing traffic signs. Determination of the location of the installation of speed limit signs and crossing road signs is coordinated with Balai Pengelola Sarana Prasarana Perhubungan Wilayah V, Transportation Agency, Central Java Province. There are four traffic signs that are installed on the Mayjen Sungkono Street, Blater which are two speed limit signs of 40 km/h and two road crossing instructions.
