<br />The consultant shall use whichever ACCMA model is the most current at the time <br />the consultant need the forecasts (Dowling Associates, lnc., as ACCMA' s <br />consultant, is currently updating the model, an cfft)rt which is expected to be <br />completed in mid-November). IYthe consultant must use the "old" model, the <br />consultant will extrapolate Year 2015 and 2030 volumes from the 2010 and 2025 <br />volumes, based on growth apparent from the two available years. <br /> <br />Dcliverables <br /> <br />Bxisting Conditiqns Memo - a summary of existing level of service and other traffic conditions <br />in the study area, including, if available, reduced size (8YlxI1) printouts of available engineering <br />drawings ofthe study area. <br /> <br />Traffic Forecast MQ[110 - documentation of methodology of obtaining forecasts and of the <br />forecasts themselves. <br /> <br />Task 2 - Traffic Operations Analysis <br /> <br />A. Enter the applicable existing tratTic data (counts, lane configurations, signal phasing and <br />coordination inputs, etc.) into the Synchro intersection analysis program, including <br />adjustments, i r applicable, to reflect results fronl the saturation tlow measurements. <br /> <br />B. Make further adjustments if the calculated results do not coincide with our field observations <br />of traffic conditions (e.g., if a calculated queue or delay is significantly longer or shorter than <br />actually occurs in the field). <br /> <br />C. Introduce the Year 2030 volumes into thc operational analysis and develop up to three <br />alternatives of lane and phasingltiming configurations to optimize operating conditions. <br /> <br />D. Enter the Year 2015 volumes to attempt to identify an interim intersection configuration that <br />could serve as an initial phase. <br /> <br />Deliverable <br /> <br />Technical MemQIgpd!J1Il- A briefmemo that reports the basic results ofthis task. Detailed <br />descriptions of inputs, assumptions, adjustments, etc. shall be included later in the Traffic <br />Assessment Report <br /> <br />Task 3 - Engineering Feasibility <br /> <br />A Review the basic altemativcs in the context ofthe available right-of-way, utility locations, <br />and other relev;Ult engineering issues. <br /> <br />B. Prepare conceptual drawings and order-of-magnitude costs of each altemative, in order to <br />compare them with one another. <br /> <br />Deliverable <br /> <br />Teglmical MemonUldum A bricfmcmo shall reports the basic results of this task. Key <br />engineering issues and brief summaries of potential solutions shall be provided. <br /> <br />Hesperian Boulevard/Lewelling J ntersection Trame Assessment <br /> <br />November 13, 2006 <br />Page 16 of21 <br />
