Each lane is calculated to provide a certain capacity. Level-of- <br /> capacity <br /> service 'D', the standard adopted in TransPlan (Eugene-Springfield Metropolitan Area <br /> ~I ~ Transportation Plan), the area's long-range transportation plan, is used as the. basis for the <br /> ' calculation. The cost of increasing capacity is based on the average cost paid by the City <br /> for each lane mile of arterial and collector streets. Note that the cost calculation excluded <br /> the assessable costs and evaluated only the arterial and collector system.

The Transportation <br /> SDC is calculated by multiplying the cost per trip (indicated by the gray shaded areas) by the <br /> units in a development, multiplied by the average trips generated for similar types of <br /> development. <br /> Typical Trips Generated per Unit =The number of vehicle trips caused by the development <br /> during the hours of peak afternoon traffc (P.M. peak hours). The P.M. peak hour trip rate <br /> varies according to land use.. Transportation facilities must be built to accommodate the <br /> peak demand, thus the use of the P,M. peak hour trip generation rate. Trip rates are to be <br /> delermined using paragraph 3, Trip Generation Rates, of this Appendix C. <br /> ' Units per Development =the unit of measure which represents the size of a development, <br /> ~ such as thousand gross square feet (TGSF). The unit value is determined by the developing <br /> project's size, and the type of units is set for each land use in Attachment #1 of this <br /> Appendix. , <br /> March 01, 1997 Methodologies: City of Eugene SDCs Page C-1 <br /> <br />
