To investigate the health impact of vehicular pollution of Kolkata (former Calcutta), a cross-sectional study was carried out during 2007-2010 among 932 male non-smoking residents of the city and 812-ageand gender-matched rural subjects as control. The urban group included 460 men who were occupationally exposed to vehicular pollution: 56 traffic policemen, 188 street hawkers, 82 auto rickshaw ...

Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...

Traffic flow systems are nonlinear and uncertain, so it is very difficult to find their optimal points. In traditional traffic control systems, the traffic lights of crossings change in a fixed time period that is not optimal. On the other hand, most proposed systems are sufficiently capable of coping with the uncertainties of traffic flow. To solve this problem, there is a need to develop expe...
