Abstract

High intensity rainfall that occurs can cause puddles if the condition of the drainage system is not well maintained. The development of Pontianak City Infrastructure has resulted in land use changes that was originally in the form of vacant land converted into residential areas or other economic activities. The existing condition of the drainage channel at M. Sohor Road is not able to accommodate rainwater discharge in the rainy season. In the existing conditions for land use, there is no rainwater catchment area. The management of floods with arranging the drainage system has been ineffective so we need an environmentally drainage system arrangement concept.  Identification of the hydrological and hydrolic conditions that exist in the catchment area of the M. Sohor channel is required. The hydrological analysis in this study includes testing the consistency of rainfall data in Pontianak City, selecting a rain distribution that matches the rainfall data pattern, calculating the time concentration, rainfall intensity and the total discharge from domestic discharge and design discharge of 2, 5, 10 years. The hydraulic analysis in this study includes the design of a channel cross section design as a channel normalization plan. The total flow discharge in M.Sohor channel for a 2-year return period is 2.22 m3/s, a 5-year return period of 2.75 m3/s and a 10-year return period of 3.09 m3/s. Environmental insight drainage can be done by planting shrub plants that can reduce air pollution such as Croton and Bougainvillea, arranging M. Sohor Road to be friendly with pedestrians controlling excess rainwater discharge caused by the rain process through rain water harvesting techniques.

Abstract

The majority of traffic accidents in Surabaya are dominated by motorcycles and drivers which whom mostly were teenagers This study aims to examine the relationship between attitudes, driving behavior, and traffic accidents among young motorcyclist in Surabaya. The study used a primary dataset of 435 motorcyclists from 17to 25-year-old. This study uses a structural equation modelling approach to determine the relationship between attitudes towards risky driving behavior, driving behavior, and traffic accidents. The driving behavior parameters used are divided into six parameters: traffic errors, speed violations, control errors, traffic violations, safety violations, and stunts. The results of this study indicate that all driving behavior parameters are significantly influenced by the driver's attitude towards risky driving behavior. In which the parameters that have a significant effect on traffic accidents are traffic errors and traffic violations.

Abstract

Motorcycle accidents remain a serious road-safety problem in developing countries, particularly among young riders who often exhibit risky riding behaviors. Risk perception is considered an important factor influencing such behaviors and accident involvement; however, the relationships among these variables remain poorly understood. This study aims to examine the relationships among risk perception, risky riding behavior, and accident involvement among young motorcycle riders. A quantitative approach was employed, using primary data collected via structured questionnaires distributed to young motorcycle riders, yielding 368 valid responses. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM), including evaluation of the measurement and structural models. The results indicate that risk perception has a significant negative effect on traffic errors (p = 0.010), speeding violations (p = 0.025), traffic violations (p = 0.002), and safety violations (p = 0.002), but has no significant effect on control errors and dangerous actions. Furthermore, traffic errors, speeding violations, and control errors significantly increase the risk of accidents. These findings suggest that improving risk perception can reduce risky riding behavior and contribute to motorcycle accident prevention efforts.
