Overall, the proportion of foot and bike experienced a downward trend, whilst car witnessed an upward trend from 1950 onwards.
As is shown by the diagrams, the rate of people who walked in 1950, comprised approximately 40%, while bike users were responsible for near 30%. Furthermore, in 1970 these rates were in decline, accounting for about 20%. Similarly, this amount finally reached around 5%, a quarter of percent that was in 1970.
By contrast, the number of drivers who used card took up from 5% to 25% in 1970, rising further roughly 40% in 1990. Turning to the bus passengers, this figure fluctuated during this period, which was responible for almost 15% in 1950 to about 25% after two decades. However, in 1990 transporting by bus fell to near 15%, nearly the same rate in 1950.
