Operational planning of cargo transportation by motor vehicles used on hourly payment conditions

In the modern practice of transporting goods in cities, the use of motor vehicles on an hourly basis has become widespread, although it is known that their use is much less efficient. The purpose of this paper is to increase the efficiency of cargo transportation in cities by motor vehicles on an hourly payment basis by developing methods for operational planning of cargo transportation in cities by motor vehicles used on an hourly payment basis and practical recommendations for its use. The developed methodology considers the existing practice of cargo transportation. By default, it is assumed that a client who rents a car on an hourly basis has the competence to organize cargo transportation in cities. In an order application, the client indicates a car, body type and order time. Thus, it seems that the decision of the client when ordering always contributes to the positive satisfaction of his needs. However, the results of the study suggest that the use of cars on an hourly payment basis for the transportation of building or commercial goods at different distances in urban environments gives different results. Applying the results of this study allows assessing customer satisfaction and prevent undesirable outcomes prior to experience.

Application of the Principle of Good Faith in Consumer Financing Agreements

Increasingly diverse community mobility now results in an increase in the need for transportation equipment, both in terms of quantity and quality, however, on the other hand the available public transportation facilities are far from what is expected. This encourages to be encouraged to have a private facility. Today the development of motorized vehicle use is increasing rapidly. This is because motorized vehicles have advantages compared to public transportation, for example in terms of comfort and safety when on the road. The increase in transportation needs also boosted the growth of Consumer Financing Institutions perceived by consumers as a simpler procedure compared to bank financing institutions. The agreement signed between consumers and the Consumer Financing Institution is a standard agreement, in which consumers have no right to determine the contents of the agreement. This leads to the frequent occurrence of defaults on the part of consumers, because consumers do not understand the contents of the agreement properly. Good faith is an agreement principle that can control the occurrence of agreements that tend to incriminate parties. This paper aims to reveal the role of the principle of good faith in the establishment and implementation of the Consumer Financing Agreement. The study method used is a normative and philosophical study method based on secondary data.

Using the abstraction hierarchy to identify how the purpose and structure of road transport systems contributes to road trauma

Research is beginning to demonstrate the merits of considering the broader road transport system when attempting to understand and prevent road trauma. This study involved the use of Work Domain Analysis, a systems analysis method, to develop a model of a road transport system based on Queensland, Australia. The model was subsequently used to identify the system wide contributory factors that play a role in road crashes, and to identify aspects of road transport systems that could be exploited when developing road safety interventions. The findings show that there are a set of crash contributory factors relating to the raison d'etre, values, and functions of road transport systems. This suggests that further significant reductions in road trauma will only be achieved through fundamental changes to the road transport system itself. Examples discussed include reducing the emphasis on the use of road transport for economic growth, reducing motor vehicle use and increasing active transport modes, and overhauling road safety strategies.

Disaster and unplanned disruption: Personal travel planning and workplace relocation in Christchurch, New Zealand

Christchurch, New Zealand, is a city dominated by car use. In the 2013 Census 84% of people travelled to work by car. In 2010 and 2011, a series of earthquakes resulted in widespread damage to horizontal infrastructure, and the relocation of many homes and businesses. Over 70 percent of buildings in the central business district were destroyed or deconstructed and many organisations, including government departments and private commercial enterprises, relocated to suburban areas.The relocation of businesses back to the central city in 2017 presented opportunities to rethink the travel network to and from the city, and to promote alternatives to private motor vehicle use such as public transport, car-pooling, walking and cycling. The Greater Christchurch Partnership undertook personal travel planning with some of these organisations to help facilitate the goals of the new transport plan. This action was based on the habitat discontinuity hypothesis that context change or disruption increases the likelihood that a behaviour will be reconsidered and different choices made.A personal travel planning programme was subsequently implemented. It included a pre-move survey (N = 834), individual interviews with staff (N = 1234) and a post-move survey (N = 624). Results showed that after businesses relocated to the central city, the mean number of trips per week made by walking, cycling, bussing and carpooling increased for those not interviewed (Group A) and those interviewed (Group B) and the mean number of trips by car per week decreased for both these groups.Results of the ANOVA showed the difference in mean trips per week between the group interviewed and the group not interviewed was statistically significantly higher for bussing after businesses moved. No other statistically significant differences were found between these two groups for any other mode.It is concluded that one-to-one interviews targeting workers about to relocate were effective in relation to bussing, but were not effective in relation to cycling, carpooling, walking and 'other' forms of transport. This study provides a unique situation involving large scale business relocation, rather than the fragmented relocation of individual residents.

Vaccination, Risks, and Freedom: The Seat Belt Analogy.

We argue that, from the point of view public health ethics, vaccination is significantly analogous to seat belt use in motor vehicles and that coercive vaccination policies are ethically justified for the same reasons why coercive seat belt laws are ethically justified. We start by taking seriously the small risk of vaccines’ side effects and the fact that such risks might need to be coercively imposed on individuals. If millions of individuals are vaccinated, even a very small risk of serious side effects implies that, statistically, at some point side effects will occur. Imposing such risks raises issues about individual freedom to decide what risks to take on oneself or on one’s children and about attribution of responsibility in case of adverse side effects. Seat belt requirements raise many of the same ethical issues as vaccination requirements, and seat belt laws initially encountered some opposition from the public that is very similar to some of the current opposition to vaccine mandates. The analogy suggests that the risks of vaccines do not constitute strong enough reasons against coercive vaccination policies and that the same reasons that justify compulsory seat belt use—a measure now widely accepted and endorsed—also justify coercive vaccination policies.

Better transport accessibility, better health: a health economic impact assessment study for Melbourne, Australia

BackgroundPhysical inactivity is a global public health problem, partly due to urbanization and increased use of passive modes of transport such as private motor vehicles. Improving accessibility to public transport could be an effective policy for Governments to promote equity and efficiency within transportation systems, increase population levels of physical activity and reduce the negative externalities of motor vehicle use. Quantitative estimates of the health impacts of improvements to public transport accessibility may be useful for resource allocation and priority-setting, however few studies have been published to inform this decision-making. This paper aims to estimate the physical activity, obesity, injury, health and healthcare cost-saving outcomes of scenario-based improvements to public transport accessibility in Melbourne, Australia.MethodsBaseline and two hypothetical future scenario estimates of improved public transport accessibility for Melbourne, Australia, were derived using a spatial planning and decision tool designed to simulate accessibility performance (the Spatial Network Analysis for Multimodal Urban Transport Systems (SNAMUTS)). Public transport related physical activity was quantified by strata of age group and sex from Melbourne travel survey data (VISTA survey) and used with the SNAMUTS Composite Index to estimate input data for health impact modelling for the Melbourne population aged 20–74 years. A proportional multi-state, multiple cohort lifetable Markov model quantified the potential health gains and healthcare cost-savings from estimated changes in physical activity, body weight and injuries related to walking to access/egress public transport under two scenarios: (S1) public transport accessibility under current policy directions, and (S2) multi-directional, high-frequency network improvements.ResultsMulti-directional, high-frequency improvements to the public transport network (S2) resulted in significantly greater health and economic gains than current policy directions (S1) in relation to physical activity (mean 6.4 more MET minutes/week), body weight (mean 0.05 kg differential), health-adjusted life years gained (absolute difference of 4878 HALYs gained) and healthcare cost-savings (absolute difference of AUD43M), as compared to business as usual under both scenarios (n = 2,832,241 adults, over the lifecourse).ConclusionsBased on our conservative analyses, improving accessibility to public transport will improve population health by facilitating physical activity and lead to healthcare cost savings compared with business-as-usual. These wider health benefits should be better considered in transport planning and policy decisions.

A case evaluation of traumatic brain injury in Wahidin Sudirohusodo Hospital, Makassar during January 2016 - December 2017

Introduction: Traumatic Brain Injury is a case that is often encountered in emergency care installation and is one of the leading causes of death in the productive age range. Globally, the Traumatic Brain Injury incident increased sharply, mainly due to the increase in motorized vehicle use. In 2020, the WHO estimated that traffic accidents would be the third-largest cause of disease and trauma in the world. In Indonesia, at Cipto Mangunkusumo Hospital Jakarta shows that the mortality rate is high in patients with severe head injuries with a percentage of 35% -50%. This figure is higher than the international literature standard. This study aims to describe the traumatic brain injury case in Wahidin Sudirohusodo Hospital from January 2016 - December 2017.Methods: This descriptive study report the evaluation of cases of traumatic brain injury patients at Wahidin Sudirohusodo Hospital Makassar, from January 2016 - December 2017. The population and sample are 1217 patients (total sampling).Result: From 1217 samples, most are men (70%), and 30% are women, with age 11-20 years are the most (30%). The most common causes of traumatic brain injury are caused by traffic accidents (89%). The largest group of patients (50%) had a mild head injury (GCS 14-15). From a Head CT scan, the most lesion was epidural hemorrhage (EDH) (26-34%) followed by intracerebral hemorrhage (ICH) (23-28%). About 36% patients were treated by operations and the rest were conservative. Based on the outcomes, about 77% were discharged from a hospital in life and 23% died.  Conclusion: The highest mortality was in severe head injury, about 87% was died (161 of 186 patients with a severe head injury). From the Head CT Scan, about 95% (19 of 20 patients) with IVH lesions were died and followed by ICH lesions as 39% (122 died from 309 patients). Based on the therapy given both surgery and conservative, patients who were discharged from the hospital in life at 77-79% and died 21-23%.

From Peripatetic Anthropology to the Ethnography of Roads and Motorisation in Africa

This paper is based on 10 months of field work between 2009 and 2014 in Cape Verde, and provides an overview of the anthropological literature in which motor vehicles and African roads are studied as social phenomena. Until the end of the twentieth century, most ethnographies have failed to focus on the countless social processes linked to the development of mobility by road and the motorisation of transportation in Africa, or on the role played by cars and roads as symbols of a globalised modernity. The paper reviews the research by authors who, from the 1930s onwards, mention African roads and the use of motor vehicles as spaces in which social situations and processes take place. The several symbolic and instrumental dimensions of the motorisation of road transportation in Africa are discussed as well.

Stable isotopes and chemical characteristics of precipitation in Hangzhou and Huzhou, East China.

Atmospheric precipitation is a very important link in the water cycle. The characteristics of major ions (n= 341) and stable isotopes (δ2H, δ18O; n= 157) were analysed in Hangzhou and Huzhou, which are economically prosperous cities in East China. The δ2H and δ18O values of precipitation ranged from - 109.70 to 21.30‰ and from - 14.87 to - 0.95‰, respectively. Compared with the local meteoric water line (LMWL) of China, the slope and intercept of the LMWL were much higher in Hangzhou and Huzhou, which is related to the effects of the humid climate and less secondary evaporation. The δ2H and δ18O values were highest in spring because of the influence of air masses from the northern Asian continent and other nearby sources. In contrast, the air masses from the South China Sea and the western Pacific Ocean in the summer had the lowest δ2H and δ18O. The dominant ions in precipitation indicate that Ca2+, HCO3-, SO42-, NH4+ and NO3- are the main ions of precipitation in Hangzhou and Huzhou, and the dilution of precipitation leads to lower concentrations of ions in spring and summer, similar to the values found in most Chinese cities. The increase in motor vehicle use resulted in a lower [SO42-]/[NO3-] ratio (1.64) of precipitation, indicating mixed acid rain in Hangzhou and Huzhou (HZS). Based on a combination of the correlation analysis, enrichment factors and source contributions, we determined that SO42- and NO3- were introduced mainly from anthropogenic activities such as coal combustion and vehicle exhaust, accounting for 89% and 99%, respectively. The strong correlation between Cl- and Na+, as well as Ca2+, Mg2+ and K+, indicates that these ions commonly have marine and crustal origins, respectively, and 40% of Mg2+ comes from a marine source.

PENGARUH PENAMBAHAN ZAT ADITIF TERHADAP KONSUMSI BAHAN BAKAR PADA MOTOR BAKAR BENSIN SUZUKI 4-TAK DOHC (16 HP)

The level of motorized vehicle use is increasing every year and will lead to high fuel consumption. Then a vehicle that has good performance and minimum fuel consumption is needed. The government introduced a new fuel, pertalite, which has better fuel quality than premium. Additive substances are ingredients that are added to motorized fuel which are useful for increasing engine performance ranging from durability, acceleration to engine power. The purpose of this test is to find out how much fuel is used when testing braking, how much fueling has been mixed with additives when braking loads occur, analyzing the reduction of fuel mixed with additives and without additives mixed. So that the resulting fuel composition without using additives reaches max torque 5,488 Joules, power 2010.4 Watts, and mass flow rate 0,000082 kg / s with fuel consumption 0,4 l /hr, from substanceless testing additives and using the most maximal additives with a time of 120 seconds, 7000 rpm and a load of 2 kg, a comparison of the reduced use of fuel is 0.06 l / h. The fuel composition using additives reaches max torque 5.488 Joules, power 2010.4 Watts, and mass flow rate 0.000071 kg / s with fuelconsumption 0.36 l / hr. Testing with additives as a mixture of fuels in certain compositions can improve engine efficiency which has a low mass flow rate, but is proportional to the torque and power produced. Based on the testing and analysis that has been done, the best mixture composition for pertalite is 1: 1.

Stakeholders’ perceptions of protected area management following a nationwide community-based conservation reform

People’s perceptions can point to reasons for conservation support or lack thereof. In this study, we surveyed the perceptions of conservation among local stakeholders who participated in protected area (PA) management following a reform towards community-based conservation in Norway. We analyzed the link between perceptions of threats to conservation values, prioritized management actions and trust in PA governance, and assessed how these perceptions aligned with the stakeholders’ preferred overarching conservation approach and their support for PAs. Conservation perceptions differed mostly between property owners and representatives of nature conservation (such as NGOs). Property owners perceived modern farming, grazing and hay making, and securing the interests of rights holders as a priority. They had a lower support for PAs and favored a conservation approach focusing on “people and nature”. Representatives from nature conservation prioritized management actions to increase biodiversity and reduce land development, had higher trust in environmental authorities and identified motorized vehicle use as a threat to conservation values. They had a high support for PAs and favored a conservation approach that mitigates threats from human activity (i.e. “nature despite people”). The nationwide reform aimed at increasing support for PAs, but 31% of the members of the stakeholder advisory councils were willing to downgrade or degazette PAs for the benefit of economic development, which is much more than general population surveys. However, the level of trust in local governance was less polarized among the members of stakeholder advisory councils compared with the former state governance, which suggests that that the community-based conservation reform has the potential to improve collaboration and conflict mitigation.

EVALUATION OF OPERATIONAL RISK MANAGEMENT IN TECHNICAL IMPLEMENTATION UNITS OF MOTOR VEHICLES IN SUPPORTING THE CONTINUATION OF LOGISTIC PATHWAYS IN WEST JAVA

Risk management is important in supporting all objectives of the West Java Province Motor Vehicle Testing Technical Implementation Unit, namely providing technical safety guarantees for the use of motorized vehicles, trailer trains and postage trains on the road, supporting the realization of environmental sustainability from possible pollution caused by motorized vehicle use. trailer and train carts on the road, and provide public services to the community. Vehicles operated on the road include bus cars, goods cars, articulated cars, train carts, special vehicles and public transportation.The application of risk management can be used in all fields of work and even in various activities, including decision making, operations, processes, functions, projects, products, services and assets (ISO 31000, 2009). In Indonesia transportation has an important role in supporting national development. Indonesia is an archipelagic country where the development of the transportation sector is designed to support the movement of the economy, national stability and also reduce development inequality between regions by expanding the reach of the distribution of goods and services throughout the archipelago. With the existence of transportation, the economy of the community is more evenly distributed so that it is expected that people's welfare will increase, because the community is easier to get the goods and services needed. One of the important facilities in the land transportation sector is motorized vehicles.Keywords: Environmental, Sustainability, Pollution, Transportation

Auto Detection of Number Plate of Person without Helmet

Automated Number Plate Recognition organization would greatly enhance the ability of police to detect criminal commotion that involves the use of motor vehicles. Automatic video investigation from traffic surveillance cameras is a fast-emerging field based on workstation vision techniques. It is a key technology to public safety, intelligent transport system (ITS) and for efficient administration of traffic without wearing helmet. In recent years, there has been an increased scope for involuntary analysis of traffic activity. It defines video analytics as computer-vision-based supervision algorithms and systems to extract contextual information from video. In traffic circumstancesnumeroussupervise objectives can be continue by the application of computer vision and pattern gratitude techniques, including the recognition of traffic violations (e.g., illegal turns and one-way streets) and the classification of road users (e.g., vehicles, motorbikes, and pedestrians). Currently most reliable approach is through the acknowledgment of number plates, i.e., automatic number plate recognition (ANPR).

Competence Disputes Relating to Liability of the Insurance Guarantee Fund and an Insurance Undertaking on the Background of Compulsory Motor Liability Insurance - Practical and Legislative Solutions

The authors of this article, having analyzed the role of the Insurance Guarantee Fund in the compulsory insurance system, show the most significant differences in the liability of motor liability insurers and the IGF towards the injured. In their opinion, the identified differences in the liability principles and the differences in the interpretation of the applicable laws are the most frequent sources of competence disputes between insurance undertakings and the Fund, particularly about the competence of one of them in the claims settlement of victims of incidents involving unidentified perpetrators. On the one hand, these disputes are essentially held over formal issues, such as the existence or non-existence of insurance cover of the perpetrator and, on the other hand, over substantive ones, namely the recognition of the liability of either the IGF or the insurer in the circumstances of the event. Owing to their complex nature these disputes are frequently long-lasting, which results in the victims waiting for an extremely long time for their compensation. The authors emphasize that in the European Union the above problem has already been identified and was mostly regulated by the Directive 2009/103/EC of the European Parliament and Council of 16 September 2009 relating to insurance against civil liability in respect of the use of motor vehicles, and the enforcement of the obligation to insure against such liability. In Article 11 of the regulation it is stated that in the event of a dispute between the guarantee institution and the insurer, about determining who must compensate the victim, the Member States are required to designate one of those parties to be responsible in the first instance for paying the compensation to the victim without delay. The Insurance Guarantee Fund has repeatedly pointed to the negative effects of the lack of full implementation of this regulation to our national legislation. It consequently must have led to competence disputes and the need for conflict resolution in courts, at the expense of victims waiting long for being paid the compensation. Having recognized the importance of the above problems, the Polish legislator finally resolved this issue by the Act of 23 October 2018, amending the act on compulsory insurance, the Insurance Guarantee Fund and the Polish Motor Insurers’ Bureau in accordance with the directive. In the above amendment it has been indicated that in the event of a competence dispute the insurance undertaking is required to satisfy the justified claims, but at the same time the obligation has been imposed on the Fund to reimburse the paid compensation to the insurer, in the situation when the responsibility of the Fund to the victim of the accident was established. According to the authors, the entry into force of this regulation on 31 December 2018 should eliminate from the market the phenomenon of justified claims being not settled in due time.

Evaluation of the Use of a City Center through the Use of Bluetooth Sensors Network

In order to achieve the objectives of Smart Cities, public administrations need to take measures to regulate mobility, which undoubtedly requires a high level of information and sensorization. Until the implementation of the connected vehicle takes place, it is still necessary to install sensors to obtain information about mobility. Bluetooth sensors are becoming a useful tool due to the low cost of equipment and installation. The use of Bluetooth sensors in cities, with short distances between sensors, makes it necessary to propose new classification algorithms that allow the trips of pedestrians and vehicles to be differentiated. This article presents the study carried out in the city of Valencia to determine the use of motor vehicles in the historic center and propose a new classification algorithm to distinguish between an onboard Bluetooth device and the same device carried by a pedestrian when it is not possible to use the travel time for the classification due to the short distance between sensors. This causes very similar or even indistinguishable travel times for vehicles and for pedestrians. We also propose an algorithm that allows vehicles to be classified according to what type of trip is made always through the historical center of Valencia, whether it is to make a shorter itinerary through the city or to access the center for any type of business. This algorithm would enable the Origin-Destination matrix of an urban network with short distances between sensors if they are available in all entries and exits. Likewise, the results obtained have allowed to positively evaluate the algorithm defined to distinguish between trips made by a pedestrian or a vehicle in a city, using the MAC address of their mobile devices with very short distances among sensors. The results of this study show that it is possible to use Bluetooth technology, with low cost installations, to evaluate the use of the city by motor vehicles.

Optimization Study of Parametric Thermal Bimetal Material Module for Green Building in Tropical Humid Climate

The largest energy consumption that we use is the consumption of electrical energy in terms of meeting the lighting needs and building air conditioning requirements (World Energy Consumption, 2016). According to the Ministry of Energy and Mineral Resources (2017), Indonesia’s largest energy use in commercial buildings is for flight systems (63%), lighting systems (20%), vertical transportation (7%) electronic devices (10%). The use of energy in the fulfillment of excessive needs result in worsening conditions on earth. Data can be a reflection of how the condition of the earth that we live at this time. Energy savings should be made to reduce the damage already occurring on this earth such as electricity usage savings, optimization of use of materials, the use of motor vehicles that cause air pollution, and others. The way that can be used to reduce artificial energy use is to utilize the existing passive building design such as the use of solar energy that can be maximized during the day, so that the use of electrical energy for lamps and artificial air conditioning. reduced. In addition, it can also be considered the optimal use of wind direction and speed that can suppress the use of Air Conditioner (AC) in excess. Building envelope with bimetal thermal material module application is part of kinetic architecture via biomimicry approach. Kinetic architecture is a concept where buildings are designed to allow parts of buildings to move without compromising the unity of the structural system. Approaches that can be applied in green building design is by optimizing bimetal material module that utilizes the thermal coefficient of a material. With this approach, building envelopes are improvised so that they can adapt to the existing environment. This research take location of case study in Kampung Juminahan, Yogyakarta, Indonesia which has characters of comunal housing.

Never mind the bollards: The politics of policing car attacks through the securitisation of crowded urban places

This paper follows an example of security bollarding in response to car attacks, now widely offered as a solution to the ‘new normal’ use of motor vehicles as weapons for terrorist attacks in crowd...

Estimation of CO vehicular emission on arterial roads in Makassar City based on Caline-4

Transportation is one of the most important and strategic of basic needs in daily life. Increased the use of motor vehicles and energy consumption in cities give an impact on air pollution, traffic jam, and public health disorder. The purpose of this research is estimate of Carbon Monoxide (CO) pollutants received in receptors on Arterial Roads in Makassar City. This research was conducted in A.P. Pettarani, Sultan Alauddin, Urip Sumoharjo, and Perintis Kemerdekaan road in peak hour of the morning, afternoon, and evening. Analysis of measurement data is using software WRPLOT View and CALINE-4. The result showed that the highest estimation of CO pollutant in A.P. Pettarani road is KFC receptors with 4,3 ppm, in Sultan Alauddin its happen in Polsek Rappocini with 3,8 ppm, in Urip Sumoharjo its happen in Ridha Allah Mosque with 1,4 ppm, and STIKES Nusantara receptors in Perintis Kemerdekaan road is the place with the highest CO value pollutant estimates, that is 4,4 ppm.

EMMISION OF POLLUTANTS ORIGINATING FROM MOBILE SOURCES ON THE EXAMPLE OF THE CITY OF KRAGUJEVAC

Traffic jam makes cities less pleasant for living and it also decreases traffic efficiency whereas travel time, fuel consumption and drivers’ stress are increased. A special problem is its influence on people’s health caused by emission of exhaust gases. Emission of pollutants originating from mobile sources is primarily conditioned by a level of technologies applied to the vehicle, vehicle’s technical state, traffic intensity, traffic density, local climate conditions, etc. Air pollution due to use of motor vehicles is becoming one of the major problems in urban areas across the world. With the increase of the number of motor vehicles and traffic intensification, the influence of exhaust gases on human environment also has increased. Considering the average age of the vehicles participating in traffic in the city of Kragujevac and the traffic capacity of traffic arteries, most frequently not designed for such a large number of vehicles concentrated at the core of the city, it is to be expected that the air pollution coming from mobile sources will become a problem that requires detailed analysis. For that purpose, a detailed statistical analysis of the vehicle fleet of the city of Kragujevac is conducted. An estimation of the influence of the vehicles on the air pollution in the city of Kragujevac, has been given in the paper.
