AECIM growth rates calculated from the RTP model SED, reconstruction of atemporary at-grade crossing to as described above. facilitate construction ofthe grade separation. 3. Future year traffic volumes will be developed for the four build alternatives described above. Railroad Permitting 4. Opening year traffic volumes will be developed We will be responsible for assisting the SCRRA/OCTA in using growth rates calculated from the RTP model obtaining the Agreement with the SCRRA/OCTA. This will SED for an intermediate year, to be determined by be done by: the PDT. 5. The resulting intersection levels of service will be Coordinate with the SCRRA/OCTA duringthe calculated using Highway Capacity Manual (HCM) development of the preliminary plan for the 2000 analysis methodologies. grade separation and solicit their input and 6. Based on the future levels of service, intersection separation requirements. lane geometrics will be identified to maintain minimum level of service standards. Request the SCRRA/OCTA to prepare the 7. The results of the traffic operations analysis will be Construction and Maintenance Agreement. presented in a technical study. This study will document the level of service analysis Meet and confer with the SCRRA/OCTA methodologies employed, existingtraffic regardingtheterms and conditions ofthe conditions, forecast future (openingyear and Agreement. design year) traffic conditions for each alternative, and improvements needed to maintain satisfactory Furnish plans and cost estimates to the operations in each analysis year.
