Surakarta is a city that has very rapid growth in many sectors such as in industry, services, settlements, education, trade and transportation. The main trading activity center or CBD (Central Bussiness Distric) in Surakarta City, is located in the Coyudan Surakarta shopping area, which makes this area becomes a strategic and congested traffic access point. This condition cause a high volume of traffic in the area. Motorized vehicle’s traffic activity on its road segment has a negative impact to surrounding area along the road segment as an air pollution. The more rapid transportation activities, especially motorized vehicles, are the main sources of air pollution in urban areas. The research method for this study is a survey method (for selecting research points) and approach analysis methods (using an empirical formula). The results of this study indicate that the parameters of exhaust emissions which include CO, HC, NO, and PM still meet the permitted air quality standards. However, it is expected that all people keep paying attention to both environmental conditions and the use of transportation facilities, as well as good traffic conditions, so that the problem of exhaust emissions due to traffic will not occur. Keywords: traffic, CBD and exhaust emissions.

One of the most important sources of air pollution, especially in urban areas, is the exhaust emissions from passenger cars. New European emissions regulations, to minimize the gap between manufacturer-reported emissions and those emitted on the road, require new vehicles to undergo emission testing on public roads during the certification process. Outlined in the new regulation are specific boundary conditions to which the route on which the vehicle is driven must comply during a legal test. These boundary conditions, as they relate to the design and subsequent driving of a compliant route, are discussed in detail. The practicality of designing a compliant route is discussed in the context of developing a route on the Gold Coast in Queensland, Australia, in a prescriptive manner. The route itself was driven 5 times and the results compared against regulation boundary conditions.

The HOV carpooling lane offers a feasible approach to alleviate traffic congestion. The connected vehicle environment is able to provide accurate traffic data, which could optimize the design of HOV carpooling schemes. In this paper, significant tidal traffic flow phenomenon with severe traffic congestion was identified on North Beijing road (bidirectional four-lane) and South Huaihai road (bidirectional six-lane) in Huai’an, Jiangsu Province. The historical traffic data of the road segments were collected through the connected vehicle environment facilities. The purpose of this study is to investigate the effect of adopting two HOV schemes (regular HOV scheme and reversible HOV carpooling scheme) on the urban arterial road under connected vehicle environment. VISSIM was used to simulate the proposed two HOV carpooling schemes at the mentioned road segment. The simulation results showed that the reversible HOV carpooling scheme could not only mitigate the traffic congestion caused by traffic tidal phenomenon but also improve the average speed and traffic volume of the urban arterial road segment, while the regular HOV scheme may exert a negative impact on the average speed and traffic volume on the urban arterial road segment.

Abstract   Air pollution is a process that causes changes in the composition of air from normal conditions, resulting in changes in air temperature. Air pollution is not only bad for health, but also has a negative impact on the environment. Currently, the Indonesian Railways Polytechnic has an Inspection Train which is not equipped with a device capable of reducing exhaust emissions. In this study, a particulate reducer was designed to reduce exhaust emissions on the Inspection Train. Furthermore, the design results were tested on the Inspection train, using 3 types of diesel fuel, namely Pertamina Dex, Dexlite, and Biosolar. This study shows that the particulate reducer designed in this study can significantly reduce emissions, namely 23.9% for Pertamina Dex fuel, 17.9% for Dexlite fuel, and 10.6% for Biosolar fuel.   Keywords: particulate reducer; air pollution; air temperature; diesel fuel.     Abstrak   Pencemaran udara adalah suatu proses yang menyebabkan terjadinya perubahan pada komposisi udara dari keadaan normal, sehingga mengakibatkan temperatur udara berubah.

Air Pollution Control

The development of industry and the increase of transportation mode are directly proportional to the decrease in air quality. Some important pollutants have a negative impact on human health and the environment such as nitrogen dioxide (NO2) and ozone (O3). Distribution of NO2 and O3 concentrations from various sources of emissions in urban areas will provide basic information in the determination of policies, programs and regulations related to air pollution control. This study aims to map and analyze the concentration distribution of NO2 and O3 pollutants in Medan City. This research was conducted by a manual sampling of NO2 and O3 at 12 (twelve) points in Medan City. The sampling of NO2 and O3 concentrations is using impinger and then analyzed in a laboratory. The results showed that NO2 pollutant concentration in Medan City ranged from 21.33-306.19 |ig/m3. Meanwhile, for O3 concentrations ranged from 19.7-205.8 |ig/m3. Mapping of NO2 and O3 concentration using Geographic Information System obtained area that has the highest concentration of both NO2 and O3 is in Sub District of Medan Belawan. Furthermore, efforts to control air pollution can be done by applying clean technology to industry and encouraging the use of mass transportation.

The Impact

The problem of road traffic is one of the key challenges that cities will have to deal with in the future. It is also a problem directly related to the concept of sustainable development. Reducing the negative impact of road traffic in future cities can be achieved through cooperation in the following areas: social—shaping customer behavior and habits, economic—changing attitudes towards owning a car, and environmental—aimed at reducing the vehicle’s impact on the natural environment. A literature review was used to identify the research gap concerning the impact of the incentive system on increasing the environmental performance of drivers under short-term rental. Referring to the research gap, the main goal of the article is to identify the attractiveness of eco-driving incentives for drivers under short-term rental. The study used the survey method. The study was based on 323 completed questionnaires (female—122 and male—201). The following methods were also used in the analysis of the results: Anderson–Darling, Mood’s Median test and Kruskal Wallis multiple pairwise comparisons. The evaluation of the attractiveness of the incentive to eco-driving depends on the characteristic of the client who rents the car. Thus, it is possible to shape incentive systems for car rental customers that can shape their positive behavior on the road. Among the most attractive incentives for eco-driving in a rented car are: the possibility of upgrading a car in the next rental, discount for future rental and free car-wash.

One of the consequences of the constant urban development in numerous countries is a growing concentration of air pollution, which adversely affects both the environment and people’s health. One of the ways of changing this negative trend is to maintain green areas and trees within cities, as they serve many ecosystem functions, including biological absorption of particles and other types of air pollution. This article provides the findings of a study carried out among the residents of Warsaw, the capital of Poland, in order to assess social awareness of air pollution and the importance of trees. The study of the residents’ awareness was supplemented with the assessment of the parameters of the trees’ capacity for pollution absorption in selected locations performed with the help of the i-Tree Eco tool, which allowed the authors to compare the residents’ impressions on the role of trees in the process of absorption of pollution with their actual potential. The analyses showed that the majority of city residents are concerned with the problem of air in the city, but at the same time failing to notice its negative impact on their health. The majority of respondents were not aware of the role the trees play in the process of pollution absorption, suggesting that there is a real need for raising social awareness of functions served by trees and green areas in urban spaces. The comparison of the city residents’ opinions on the importance of trees in the process of pollution absorption with objective data obtained with the help of i-Tree Eco tool shows that the majority of people’s impressions of pollution absorption by trees in urban areas is correct.

Environmental concerns have continued to be on the increase as human activities soar. One such environmental concern is air pollution. A major contributor to air pollution is the road transportation activities. This paper sets out to provide a management strategy for air pollution owing to road transportation in urban areas, with Owerri Nigeria as a case study. A field study was conducted in Owerri to ascertain the total passenger requirement, number and mix of passenger vehicles as well as measure three main road transport-induced air pollutants at five locations in the city. The result of the field work showed existing commuter vehicles mix of 56.2:63.7: 19.6:1.6:1 of salons, wagons, mini-buses, coaster buses and big buses respectively, of a total of 85,950 vehicles and air ambient pollutants level higher than the recommended standards. A new model was developed to achieve a remix of 10:33:53: 14:1 of same vehicle types and reduction in traffic volume and target air pollutants. The analyses show that mini-buses and coaster buses have advantage over salon cars, wagon vehicles and big buses in terms of traffic congestions and pollutants release into the environment. The two bus types could be said to have least pollutants release per passenger carried. An optimal vehicle remix, which gives higher priority to these buses have been shown to reduce congestion by 40%, Carbon monoxide by 40%, Nitrogen Dioxide by 50% and Methane by 50%. It therefore recommends that vehicular remix of 10:33:53: 14:1, for salon: wagon: mini-buses: coaster buses: big buses be adopted for Owerri commuters’ transportation need. It concludes that governments should adopt economic instruments embedded in a “push and pull” strategy, leveraging on disincentive and incentive measures to skew road transportation to the use of mini and coaster buses as a deliberate means of reducing air pollution in cities.

The purpose of the study. Hygienic evaluation of discharges from the road-vehicle complex to justify recommendations for handling it in urbanized areas. Material and methods. The object of the study was discharges from the road-vehicles complex (RVC) in four cities of Russia - Saint-Petersburg, Chelyabinsk, Perm and Ufa. The research program included the analysis of the chemical composition of RVC discharges; determination of hazard classes of waste for the health of the person at the SP 2.1.7.1386-03 “Sanitary rules on determining the hazard class of toxic production wastes and consumption” (2003) and the calculation of class of danger according to the degree of negative impact on the environment in accordance with the “Criteria for classification of wastes of hazard classes I-V according to the degree of negative impact on the environment” (2014). Results. In the analyzed samples silicon dioxide (up to 92%) appeared to be the main component of RVC discharges in cities of Petersburg, Perm, Chelyabinsk and Ufa. In RVC discharges the content of seven chemical substances hazard class 1 and 2 exceeded their MPC in soil: copper - by 10 to 35 times, Nickel - from 2.6 to 61.7 times, zinc - from 3 to 5.5 times, arsenic - from 2 to 4.4 times, chromium - 2.1 to 36.6 times, cobalt - from 1.3 to 2.8 times, benzo(a)pyrene from 1 to 4.4 times. According to class of danger to human health RVC discharges waste in four cities refer to hazard class 2- highly hazardous waste, and on the basis of indices, the total index of hazard waste for the environment to hazard class 4 - low hazard waste. Mandatory collection and removal from RVC from urban areas is recommended. It is necessary to perform additional studies to assess of migration-water hazard index RVC discharges with the aim of the determination of regulations for its disposal and storage outside the city.
