This paper tries to make study of the Improvement of highway capacity due to cycle track in urban area. As urban areas develop in our country and the world, some issue related to urbanization such as traffic congestion became a serious issue. Cycle tracks are exclusive bicycle facilities that are physically separated cyclists from motor vehicle lanes. Cycle tracks are important part of infrastructure proven to increase ridership and improvement in highway capacity. Increasing bicycling can improve the overall quality in the urban areas. A separate cycle track can increase the speed of remaining vehicles so that it can save time, fuel consumption, wear and tear, reduce pollution etc. It can also increase the transportation choices, reduce parking and traffic congestion. In urban planning, cycle tracks are designed to encourage bicycling to an effort to relieve traffic congestion and reduce pollution, reducing bicycling fatalities and injuries by eliminating the need for cars and bicycles to journey for the same road space and to reduce overall confusion and tension for all users of the road. Cycle track may be one-way or two-way, and may be at road level, at sidewalk level, or at an intermediate level. I tried to find improvement of highway capacity if we construct cycle track in urban area. For this I did survey work on Chinhat to Dewa section of Itaunja-Mahona-Kumhrawa-Kursi-Dewa-Chinhat road, Lucknow. I did two way classified traffic survey of the road and also calculate average speed of commercial vehicles, personal vehicles and two wheeler vehicles except cycle. We studied of speed of commercial vehicles, personal vehicles and two wheeler vehicles based on algorithm that there will be no cyclist on mixed traffic. Lastly we studied and comparison of fuel consumption, wear and tear cost, air pollution cost, accident cost etc and as well as total cost saving due to separate cycle tracks
