In vibrant Thailand, the city of Bangkok pulses with life! Covering an area of over 1,550 square kilometres, it is estimated that over ten million people live there, over 15 per cent of the country's population. The capital city is home to a bustling urban infrastructure, featuring a complex network of traffic circles and highways. In 1864, the completion of Charoen Krung Road marked a turn in the city's transit by serving as a pioneering construction project utilising western techniques. The introduction of a complex elevated expressway network in 1972 and the Don Mueang Tollway has made it easier to drive in and out of the city. Over the years, the road network has evolved to meet the demands of this sprawling urban expanse.
