<br />1. Network Development <br /> <br />A computerized network which classifies each roadway within the <br />City as a collector, minor arterial, principal arterial, or interstate is <br />developed. The network represents existing roadway plus <br />committed roadway improvement projects. Attributes of the street <br />network in the modeling procedure include: <br /> <br />. Roadway speed relative to other roadways in the network <br /> <br />. Roadway capacity based on the number of and width of <br />travel lanes <br /> <br />· Distances between intersections included in the network <br /> <br />2. Trip Table Development <br /> <br />The trip table was developed by: <br /> <br />. Determining the number of trips being generated in each <br />study area T AZ based on the level of socioeconomic data <br />and trip generation factors developed for the area. <br /> <br />. Distributing the trips being generated between TAZs within <br />the study area and between study area T AZs and external <br />station locations using the gravity model. Using the gravity <br />model, trips are distributed in direct proportion to the <br />relative size of a T AZ and in inverse proportion to the <br />relative distance between TAZs. <br /> <br />Trips within the study area were divided into categories based on <br />the purpose of the trip. For this study, the following trip purpose <br />categories were used. <br /> <br />a) Home Based Work - Trips between the home and workplace. <br />The origin or the destination of the trip is the home. <br /> <br />b) Home Based Other - Trips between the home and any other <br />non-work place destination (i.e., shopping, school, recreation, <br />etc.). <br /> <br />c) Non-Home Based - Trips which have neither an origin or <br />destination at the home place. <br /> <br />Roseville Comprehensive Plan - 2003 Update Transportation - Page 17 of 28 <br />
