Truck Driver Behavior and Travel Time Effectiveness Using Smart GPS

The pattern of coal transportation is very dependent on the behaviour of the driver, which influences the effectiveness of travel time. Good driver behaviour will affect the optimization of travel time, and scenarios need to reduce travel time wastage. This study aims to optimize travel time and sensitivity analysis based on the influence of driver behaviour, truck travel movements and the use of travel time on coal haul roads. The research method uses a field survey with a GPS tracker, a smart GPS server 3.3, google earth and statistics. The results showed that the driver's behaviour greatly influenced the pattern of use of travel time and truck travel speed. Coal transportation in the morning can be more optimal than night so that that travel time wastage can reduced by 40%. The proposed optimization scenarios can save 36.7% - 48.61% of the existing travel time and the transport cycle can be increased to four to five times. So that with the addition of the cycle, it will increase the income of the transport company and the driver's income. With smart GPS, companies can improve the performance of transportation services in company management, get coal supplies on time

Analysis of bus performance on the risk of traffic accidents in East Java-Indonesia

Bus transportation performance must be able to demonstrate safety performance capabilities, one of which is the condition of the vehicle. Therefore, to achieve bus vehicles' safety performance, research must be carried out to determine the causes of accidents. This study aims to determine the causes of accidents related to vehicle conditions. Some of the variables that are observed include brake, wheel, equipment, stability, and worthiness. The data collection method used is to collect secondary data on the incidence of accidents from each Resort Police Office in each district traversed by the intercity public bus route. The roads traversed by the public bus transportation routes between the cities that are the object of the study include Sidoarjo Regency, Pasuruan Regency, Probolinggo Regency, Mojokerto Regency, Madiun Regency, and Ngawi Regency. The analytical method to obtain mathematical modeling is to use Principal Component Analysis (PCA). The results show that five factors analyzed, four main actors, cause intercity bus accidents, namely brakes, wheels, stability, and worthiness. The four factors are interrelated with each other, where these factors support each other and trigger accidents and obtained a mathematical model of the factors causing the accident which can be explained by two mathematical equations, namely PC1=0.61X1+0.70X2+0.46X3+0.63X4+0.72X5 and PC2= 0.47X1 0.17X2+0.76X3 0.26X4+0.31X5. The study results also illustrate that accidents caused by an inappropriate wheel are always followed by a breakdown of the braking system that is not functioning properly, and the wheel system consisting of wheel and brake conditions will be a problem triggering the acciden

Evaluation of Road Roughness and Road Deterioation

There are two road condition survey methods commonly used, the roughness-based equipment such as NAASRA and the distress and severity type road evaluation method as presented by ASTM D-6433. The objective of the study is to evaluate the relationship between road condition obtained from roughness type equipment and road distress. To achieve the objective, a condition survey using the two methods were performed on two road segments in the East Java Provincial road system. Data obtained from the field was evaluated to obtain International Roughness Index (from NAASRA) and Present Condition Index value (from field condition survey). The results show that the two methods provide a comparable result when the distress type is of un-even surface such as rutting and bumping. A slight different result is observed when the major distress occurred in the road is of crack-type such as fatigue and block cracking

ROAD RECONSTRUCTION WORK ZONE MANAGEMENT TOWARD A GREEN CONSTRUCTION CONCEPT

Abstract During road reconstruction period, a negative impact was imposed on road users and the surrounding environment. These impacts are the result of the work zone which is used as working space and road reconstruction. This work zone is potential to influence the drivers' stress and to decrease road traffic performance such as travel delays, congestions and road accidents. Guidelines for green (environmentally friendly) infrastructure defined in New Road Construction Concept (NR2C) in European infrastructure vision 2040 concept, can be used to mitigate this negative impact. Twenty projects of Balai V National Roads Improvement in East Java, and Balai VIII in Bali for fiscal year 2013 is used as a case study. Descriptive method used for the discussion of case studies. Management traffic safety in work zones assessed the suitability of the setting up of signs, markings and guardrail. Shift arrangements work during the day (peak hours) or night (off peak hour), is used as an indicator of the negative impact of road users and the environment. The analysis showed that the work zone management in the implementation of national road reconstruction projects toward green (environmentally friendly) construction concept. It is shown from the implementation of safety attributes average 68%, and the implementation of the reconstruction in the off peak hours by 55% of the projects. Keywords: road reconstruction, work zone, negative impact, green construction  Abstrak Pada saat pelaksanaan rekonstruksi jalan, dampak negatif akan  terjadi pada pengguna jalan dan lingkungan sekitarnya.

The Development of Motorcycle Accident Models Based on Riders’ Characters

Human errors have commonly been perceived as the dominant cause of accidents. Different individuals may behave differently towards certain situations, leading to accidents. This study aims to model the relationship between the riders’ personalities, riding performance, and the probability of being involved in an accident. Adding mindfulness as a mediating variable and demographic factors as moderating variables are also essential points to developing the model. The Big Five Inventory (BFI) and Mindful Attention Awareness Scale (MAAS) were used to measure the respondents' traits, while the Honda Riding Trainer (HRT) was used as a simulation tool. The Structural Equation Modelling (SEM) analysis shows that only the neuroticism variable significantly predicts mindfulness and riding performance. The openness and conscientiousness variables only significantly predicted mindfulness, while agreeableness is the only Big Five personality that significantly predicted riding performance. The results also show that although the mindfulness (M) variable in this study has not been able to become a mediating variable, it is strong enough as an exogenous variable for riding performance. The logistic regression analysis found that the worse the rider's performance, the greater the chance of an accident. Female riders are more than twice as likely to have an accident as male riders. These results indicate the need to research road safety that is differentiated by sex and its characteristics based on it. Doi: 10.28991/CEJ-SP2023-09-018 Full Text: PD

KEBIJAKAN PENATAAN JARINGAN TRAYEK ANGKUTAN UMUM PERKOTAAN JEMBER

Abstract A thriving city should have a reliable public transport system. A continued decline in the performance of services can not be separated by a detachment of people using public transport, as uncomfortable and unreliable existing services, until unresolved overlapping route yearly by the regulator. Restructuring the route network and preposition institutional arrangement of public transport management are needed to improve public transport services in the community. Restructuring the route network into two, namely: first, the subsidiaryp route network that serves the main line of Jember city use the concept of road based public transport (BRT) with medium buses; second, develop twigs routes of feeder line to serve distrct road network in urban areas. Formulation of public policy was conducted through four stages: formulation of the problem, preparation of policy agenda, selection of policy alternatives to solve the problem, and determination of the policy to minimize the two groups resistance (pro and contra).                                                                                  Keywords: policy formulation, policy agenda, problem solving, policy setting  Abstrak Sebuah kota yang berkembang harusnya memiliki sistem angkutan umum yang dapat diandalkan. Terus menurunnya kinerja pelayanan tidak lepas dari menjauhnya masyarakat menggunakan angkutan umum karena tidak nyaman dan tidak handalnya pelayanan yang ada, hingga overlapping lintasan trayek yang sudah bertahun-tahun tidak terselesaikan oleh regulator. Penataan kembali jaringan trayek dan kelembagaan pengelolaan angkutan umum diperlukan untuk meningkatkan pelayanan angkutan umum di tengah masyarakat. Penataan jaringan trayek dilakukan terbagi dua, yaitu: pertama, jaringan trayek cabang yang melayani jalur utama perkotaan Jember menggunakan konsep angkutan umum berbasis jalan dengan armada bus sedang; kedua, jaringan trayek ranting yang melayani jaringan jalan kabupaten di kawasan perkotaan yang semakin berkembang. Formulasi dalam kebijakan publik dilakukan melalui empat tahapan, yaitu: perumusan masalah, agenda kebijakan, pemilihan alternatif kebijakan untuk memecahkan masalah, dan penetapan kebijakan dilakukan untuk mengurangi resistensi dua model kelompok (pro dan kontra). Kata kunci: perumusan kebijakan, agenda kebijakan, pemecahan masalah, penetapan kebijaka
