Abstract
Designing of modern transport systems involves the need to meet a large number of requirements. The influence of designed road infrastructure on the environment is very wide and important. The most valid aspect in this case is the reduction of emissions of harmful compounds by increasing the fluency of vehicles flow and building collision free road intersections. But it should be started from establishing the initial emission level of harmful compounds. This paper presents a methodology for determining exhaust emissions from vehicles moving on the national road no. 50 in area of Zyrardow. Modern measuring tools such as the PEMS and the microscopic road simulation software, using the application to determine exhaust emissions, were used for this purpose.
Highlights
Important issues in case of the impact of automotive on the environment are traffic congestion, its fluency and the share of heavy vehicles
The directions of development of road infrastructure and transport systems have been included in the relevant documents: European Transport Policy [2, 3] and Transport Policy of the Country 2006-2025 [4]
Reducing the negative impact of transport on the environment can take place in many ways. Most often these actions are directed towards changing vehicles moving on the road to more environmentally friendly. Another aspect that can contribute to reducing environmental pollution is a well-designed road infrastructure that ensures the smoothest possible flow
Summary
Important issues in case of the impact of automotive on the environment are traffic congestion, its fluency and the share of heavy vehicles. To accurately assess the exhaust emission of a single vehicle and the entire traffic stream, existing and new designed road infrastructure, there should be the appropriate method selected. Computer simulations are gaining popularity, which has several advantages, including the ability to change arbitrary the traffic density and parameters of the road infrastructure, limited only by the functionality of the software, and time savings compared to traditional methods. In future the authors will determine the influence of road infrastructure on particulate matter emission This aspect needs to be considered very precisely, because there are some important cases that must be taken into consideration, as: mass and number evaluation or particulate filter regeneration [8,9,10]
