Transportation study metropolitan CEBU

Abstract

In this transportation study attention is paid to the most normative issues that influence the traffic circulation in a fast growing Metropolitan. Impacts of new infrastructure are being analyzed with the help of existing mathematical models in order to describe a new or adapted policy with regard to urban and transportation planning. This is done in general terms and also illustrated with the case Metropolitan Cebu, the second fast growing Metropolitan in the Philippines. In order to describe a proposed land use and transportation strategy for Metropolitan Cebu it is necessary to get insight in the actual (traffic) situation in Metropolitan Cebu. A distinction is made between demographic and transportafion characteristics. A socio-economic profile is given in which several tables and maps illustrate trends and growth rates of among others demographic information. The combined population in Metropolitan Cebu is approximately 1.5 million; the total population of only Cebu City is approximately 700,000 Metropolitan Cebu is suffering from severe congestion and other related traffic problems that have laid a base for the objectives described in the Metro Cebu Development Projects (MCDP). Some of these projects have already been completed while other projects that are part of the MCDP phase 3 are still in the implementing phase. For the MCDP phase 3 a reclamation area and a coastal highway are being constructed. When completed the reclamation area will house approximately 100 000 employees. The coastal highway will serve the through traffic coming from the southern part of Metropolitan Cebu and going to the north and will also serve the extra generated traffic flows by the reclamation area. Before using the available information and applying this data in a transportation model the theory behind transportation modeling is described. The classical four stage traffic model is explained. In this model four steps are distinguished which refer to four different quantities of traffic volume. The first two steps describe how often people make trips as a function of their personal and spatial conditions and how these trips are distributed over the different zones in the study area (trip generation and trip distribution). The third step is a sub model that determines which transport modes the travelers will use for their trips (modal split). The last step deals with how travelers choose routes through the network (traffic assignment). Once the scientific theory is described and explained on the basis of the case Metropolitan Cebu the model can almost be applied. The first calculafions can be made when the necessary input for the model is obtained. The necessary demographic characterisdcs, that are the main ingredients of the total input, will be put in order and in case of lack of data obtained by calculations such as linear trend extrapolation. It is important to keep in mind that only the demographic characteristics of population and employment are taken in consideration and that the obtained results are with regard to work-home trips. The first calculations are with regard to the total number of work-home trips that are produced and attracted (trip productions and attractions) by the 12 traffic zones in which Metropolitan Cebu is divided, this is done for both a present and future situation.
