تأثیر فاکتور انسانی بر تشکیل رسوب در راه های شهری

Road urban transport and traffic engineering in general are long-term discussed topics. Traffic problems are solved from many aspects, such as transport infrastructure, transport organization, high share of car traffic, a negative impact on air quality, emissions etc. Finally, the problem of traffic congestion on urban roads is also highly topical. With increasing economic development of individual states the numbers of cars are increasing as well − the traffic volumes are increasing at the expense of road capacity. The paper deals with the formation of congestion particularly on urban roads, where the driver reaction time influences the size of congestion as well. In the first part of the paper the issues of traffic flow and congestion formation are theoretically discussed. The second part of the paper outlines in practice an influence of human factor (the driver's Perception − Response Time) on the congestion formation.
