Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 19 April 18, 2019 3.0 Year 2040 Conditions Increases in vehicle traffic resulting from regional infrastructure, regional connectivity, business and residential development, and demographic changes will influence the long-term operation of the Lexington Avenue corridor and corresponding intersections. This traffic study evaluated intersection geometric and traffic control needs based upon the forecast year 2040 design horizon. The following section documents the forecast year 2040 conditions analysis completed for the Lexington Avenue corridor. 3.1 Trip Generation To account for traffic impacts associated with the ongoing Lexington Station development (see Figure 6), trip generation estimates were developed for the weekday a.m., midday, and p.m. peak hours as well as on a daily basis. The trip generation estimates were developed utilizing trip generation rates for similar land uses as documented in the ITE Trip Generation Manual, 10th Edition. The ITE Trip Generation Manual provides peak hour and daily trip generation rates based on studies of similar land uses. 3.1.1 Lexington Station – Phase 2 Lexington Station – Phase 2 was observed to be complete with approximately 50 percent of retail space occupied at the time of data collection (September 2018). No additional trips were included for the remaining 50 percent of the development as background growth rates included as part of traffic forecasting will provide appropriate estimates of side-street growth through the year 2020. 3.1.2 – Lexington Station – Phase 3 The ITE Trip Generation Manual was utilized to estimate the trip generation potential for Lexington Station – Phase 3, which is expected to be complete in 2021. Estimated site generated traffic for the Lexington Station Phase 3 development is detailed in Table 5. It should be noted that midday peak hour trips were assumed to be equal to p.m. peak hour trips to provide a conservative estimate of generated trips. Table 5.
