What has been depicted in the diagram is the map of changes that took place at a city hospital between 2007 and 2010. Overall, there was the addition of public parking, bus stations, and roundabouts, along with the expansion of transportation.
According to the graph, in 2007, surrounding the hospital was Ring Road, which was connected to City Road by Hospital Road, surrounded by six bus stations. However, by 2010, roundabouts had been added on both sides of Hospital Road, and two small lanes had been built off Hospital Road to link up with the new bus station.
Additionally, what is particularly notable is that the car park, used by both staff and the public in 2007, was located on the west side of Hospital Road; however, in the following three years, it was divided into two separate places, with the first one remaining unchanged, and the second one being constructed in the southwest of Ring Road.
