This thesis deals with the topic of trip generation calculation, which is used in traffic studies to determine current and future traffic volume. A review of current methods for trip generation calculation is done. Strengths and weaknesses of each method are assessed. Based on review of the current methods and literature a methodolgy for creating an activity based trip generation tool is chosen. Main reason for creating a new tool is the lack of locally based data needed for performing calculations that will be accurate fort the territory of Slovenia.
The tool created for calculating trip generation is split into two parts. First part is meant for making calculations on the level of traffic models, the second part is useful for calculations on specific locations. For the purpose of creating the tool a set of socio-economic data is gathered, inquiries at the companies are made and traffic is counted for the areas of specific activites. With the help of gathered data travel habits of people are differentiated based on the regions and municipalities of Slovenia.
At the level of individual locations calculations of the tool are compared with calculations of existing methods. Results show a good match in the amount of generated traffic fort he majority of activities. The created tool at this level has already proven to be useful in a traffic study needed for a detailed spatial plan.
A comparison of tool based results on the level of traffic models with results of existing macroscopic traffic model for the greater urban region of Ljubljana is made. Validation of results with statistical data is also performed. Suggested trip generation model that is used in the tool follows a simmilar logic to the existing model for the greater urban region of Ljubljana and provides comparable reults.
