“…Conversely, drivers decelerate to avoid collisions with other vehicles, to stop at traffic lights, to reduce their speed at speed limit areas, and to negotiate speed bumps and pedestrian crossings. Unfortunately, these changes in speeds due to acceleration and deceleration, are the main sources of vehicles emissions [8,9,[17][18][19]26]. Also, in congested traffic, higher emissions are produced at low speeds [1,2,27,28].…”

“…Traffic emissions are identified as one of the primary sources of air pollutants, those with major potential health impacts are carbon dioxide (CO 2 ), nitrogen oxides (NO x ), volatile organic compounds (VOC) and particulate matter (PM) [2,3,7,8]. Actually, traffic emissions account for up to 80% of the total PM emissions [8,9]. Additionally, the main sources of NO x in urban areas are traffic emissions, these NO x react with other chemicals to generate ozone (O 3 ), both detrimental to human health [2,10,11].…”

“…The previously mentioned air pollutants, CO 2 , NO x ), VOC and PM are primarily generated by changing speed and due to the wear of tires by braking [8,9,[17][18][19]. Changing the speed of a vehicle is a common action of every driver during a journey.…”

“…Although their effect on traffic flow and pedestrian safety has been widely studied [21][22][23][24][25], there are few studies on their effect on air quality and pollutants generation. Some works monitor pollutants using specialized equipment mounted on cars or installed at control sites [1,2,9,[18][19][20]23]. Some others recommend to increase the number of traffic-calming measures and reduce the distance between them to improve safety on pedestrians [22,25].…”

Bad air quality due to free pollutants such as particulate matter (PM), carbon dioxide (CO 2 ), nitrogen oxides (NO x ) and volatile organic components (VOC) increases the risk of long- term health diseases. The impact of traffic-calming measures on air quality has been studied using specialized equipment at control sites or mounted on cars to monitor pollutants levels. However, this approach suffers from a large number of variables on the experiments such as vehicles types, number of monitored vehicles, driver’s behavior, traffic density, time of the day, elapsed monitoring time, road conditions and weather. In this work, we use a cellular automata and an instantaneous traffic emissions model to capture the effect of speed humps on traffic flow and on the generation of CO 2 , NO x , VOC and PM pollutants. This approach allows us to study and characterize the effect of many speed humps on a single lane. We found that speed humps significantly promote the generation of pollutants when the number of vehicles on a lane is low. Our results may provide insight into urban planning strategies to reduce the generation of traffic emissions and lower the risk of long-term health diseases.

The purpose of this research is the developing of decision support system (DSS) by integrating all working information systems (ISS) for wastewater pollution evaluation processes by contributing in achieving the common goal of the Helsinki Convention (HELCOM) for countries to preserve and restore the ecosystems of the Baltic Sea. Research methodology based on design approach for the development of DSS as a multi-layered system with the multi–componential, interoperable structure of databases (DBs), data warehouses, and IS, which are under the responsibility of different public administration institutions. Findings – presented results on integration of information sources and collaboration workflows help in searching of suitable indicators for revealing the situations of water pollution from wastewater bodies and objects in districts of Lithuania and the effluxes in the Baltic Sea. Research limitations – the complexity of pollution processes and the multi-layered structure of distributed ISs under different responsibilities identify problems and requirements for adequate DSS working online. Practical implications – the results will help for influencing the decisions provided for responsible institutions of Lithuania and other members of the HELCOM, responsible for the protection of the marine environment of the Baltic Sea. Originality/Value intend to assess the sustainability requirements in the wastewater sector, by providing integrated collaboration of ISs.
