and more cars are running in many cities.
Although the car is a very convenient vehicle, it causes serious problems inside city: traffic jams, car accidents, air and noise pollution, and so on.
The streetcar can be one of the solutions for these problems.
It does not give off gas in the city, it does not cause congestion, it can be friendly to the elderly, to children, and to disabled people.
In this project, I analyze the existing
line in my hometown of Kagoshima,
Japan, as an alternative for cars,
The map to the right is a map I digitized from a paper map of Kagoshima (2002 source). It covers about 30km from left side to right side. Orientation is north to the right and tipped very slightly toward the top edge.
In this paper, based on a larger project, the role of an animated map is emphasized.
|In Kagoshima City, the streetcar line
the Central Business District (CBD) to the Southern Residential area.
The total length of streetcar lines
is 13.1km. Kagoshima City is a car-oriented
most people use cars. Walking comes second. About 18% of people use the
public transportation system. This fact suggests that more
convenient public transportation
systems might prevent increasing car usage.
The theme of this paper is to begin to identify The Possibility of Extending the Streetcar Line in Kagoshima City, Japan. In order to develop the recommendation, it is necessary to conduct a demand analysis. One important factor in that analysis is to assess the current usage (demand) of streetcar lines. Thus, I will investigate, using animated maps, the current usage (demand) for streetcar lines.
The animated maps below show current streetcar usage: thicker lines (Figure 1) indicate heavier flows of passenger traffic [ed. much as maps of the Napoleonic armies traced declining numbers of soldiers on the eastward thrust to Russia]. In Figure 2, larger circles at streetcar stops mean heavier passenger usage. The survey was conducted on May 18, 2001, by Kagoshima City Transport Company. Data includes all passengers over 5 years old on that day.
The remarkable fact is that the stop with the most passengers' usage is not in city center, but in the suburb, Taniyama, which is located at the south edge of the streetcar line. That implies that the Taniyama streetcar stop is used not only by Taniyama area residents, but also by the residents around Taniyama area.
The other stops with many passengers' usage are more of the sort one might expect:
