Both parties recognize that City staff may not be able to provide ail information requested. TASK 4. PREPARE PEAK HOUR TRAFFIC FORECASTS Objective: Identify year 2010 weekday traffic volume forecasts for major roadways in the City of Fayetteville and convert to AM and PM peak hour volumes. Approach: This task consists of :he creation of year 2010 "most likely" AM and PM peak hour traffic forecasts. Subtasks include the following: a. Examine AHTD's 1980 and 2010 weekday traffic assignments and compare against current counts and existinejprected land use data. b.

[Note: the inventory excludes "local" streets that were not coded in AFITUs traffic model network]. c. Assis: City staff :n :he adjustment of the "rawcomputer forecasts to obtain realistic year 2010 weekday traffic volume estimates; incorporate the estimates into the roadway network datanase. d. Based on available (or synthesized) K Factors and directional distributions, convert the 2010 weekday traffic volume estimates into AM and PM peak hour directional link volumes and add to the network database. e. For the intersections identified in Task 2.d, translate the AM and PM peak hour directional link volumes into turning movement volumes. Product: One (1) reproducible original of a memorandum documenting the findings of this task; one (1) diskette containing the roadway network database (in Lotus 123 format). City Supporj: We expect Ci y staff to perform the following: • Work closely with AIITD staff in the adjustment of AHTD's yea:- 2010 weekday traffic volume estimates. • Identify the changes to the existing roadway system that will represent :he current year 2010 "baseline" network. • Assist in the creation of reasonable K Factors and directional distributions. A - 4 TASK 5. ANALYZE PEAK HOUR FORECASTS Objective: Identify future peak hour levels of service and capacity deficiencies in the roadway system. Approach: We will identify year 2010 :evels of service for a baseline condition ir. which the future roadway network consists of the existing network plus improvements already programmed for construction. This task consists of two types of analysis: a. A link -level volume/capacity analysis for all major roadway segmer.ts. For sum:nary purposes, .he segrnen:s will be sorted from the highest to the lowest volume/capaci:y ratio. b. An intersection capacity analysis for the intersections identified in Task 2.d.

Conduct AM and PM peak period data collection (for estimation of AM and PM peak hour turning movement volumes) at six locations: • Mt Comfort/Garland and adjacent side streets • Happy Hollow/Huntsville • Cato Springs/South School • Sycamore/Garland and Deane/Garland • Millsap/North College • Green Acres/College 2. Perform a current -year AM and PM peak hour traffic operations analysis of the Mt. Comfort/Garland location; perform a current -year AM and PM peak hour signalized intersection capacity analysis for the remaining five locations. 3. Examine the results of Task 2 and identify modifications required to achieve a reasonable level of service. 4. Prepare year 2010 estimates of AM and PM peak hour turning movement volumes. 5.
