Lak Si is regarded as a convenient transit place since it connects to many routes, including Vibhavadi Rangsit Road, Ngam Wong Wan Road, and Chaeng Watthana Road. These roads provide access to a variety of sites, as well as a good road with wide lanes. Moreover, there are various public and private government sectors surrounding, which are densely populated, making the area congested with the traffic. Despite this, the Don Muang Toll Way is a special route that avoids traffic jams. Moreover, there is also public transportation, SRT Dark Red Line, which was developed and opened recently, including Thung Song Hong SRT and Lak Si SRT. In addition, The BTS Pink Line will be opened in the future with 2 stations, such as Chaeng Watthana 14 BTS and Bang Bua BTS. However, the bus is a good choice for public transportation because it is inexpensive and there are many bus lines that run throughout the whole day, including bus no. 52 (Pak Kret - Bang Sue), bus no.150 (Happy Land - Pak Kret), and bus no.51 NGV (Kasetsart University - Pak Kret), etc.
