GIS and Remote Sensing in urban transportation planning: A case study of Birkenhead, Auckland

  ater years the corner carried on the tradition of being the centre of transport, and Birkenhead Transport Limited later taking on the site (Haddon, 1993, pp. 34-36).

Birkenhead Transport Limited is currently the major private operator of scheduLED bus services on the North Shore. The realm of this company cover much more area than the four suburbs mentioned above. The scope of this research, however, is determined by the available remote sensing data. Bus transportation in Birkenhead is considered to be one of the most important services in the region. The adequacy of bus routes and bus stops is a vital aspect not only to the population of the area but also to the planners in North Shore City. Therefore, by integrating the capabilities of geographic information systems and remote sensing, bus routes and bus stops in Birkenhead Region are studied as a problem in urban transportation planning.

1.2 Research Objectives
This research has the following three main objectives:

1. To draw accurate maps showing existing bus routes and bus stops in the study area.
2. To evaluate the adequacy of Birkenhead bus routes and bus stops for the residents of the region. This is determined by generating buffer zones around the sides of the roads in the case of the bus routes and around given points in the case of bus stops.
3. To recommend modification schemes to certain routes or stops depending on the level of adequacy in both facilities. It is aimed that the percentage of a land-use cover inside certain buffer zones in the region can help in determining the acceptance or the rejection of two assumptions related to such an adequacy.

1.3 Assumptions of the Research:
This research has the following assumptions:

1. It is assumed that bus routes in the Birkenhead region are adequate if 80 percent or more of the
