Transit network design

Due to air pollution and traffic congestion brought on by the fast development in urban travel demand, there is an increasing need for alternate means of transportation in metropolitan areas. By reducing the negative effects of network congestion, a transit system may significantly contribute to improving the sustainability of transportation in these places. A substantial fraction of customers may be persuaded to leave their own vehicles at home and take public transportation instead if the service quality was comparable to that of the automotive mode. By reducing the number of circulating cars and raising the average speed of traffic flow, a competitive transit system can increase user mobility and lower emissions from circulating vehicles. However, the amount of network travel demand that a transportation system captures primarily relies on the level of user service it provides. As a result, it's critical to balance operating costs with service quality by reducing the social, economic, and environmental costs associated with putting in place an effective and sustainable transportation system design.
