Comprehensive Plan Transportation Element o Transit Alternatives With respect to transit, the Indian River County MPO modeled expanded transit service on the 43rd Avenue Corridor as part of the recently completed five-year Transit Development Plan — Major Update. According to consultant estimates, expanded transit service on 43rd Avenue operating at the system standard one-hour headways would result in 10,843 riders/year. On a peak -hour basis, this would translate into approximately 1,000 riders. Divided out over 250 annual service days, the impact of expanded service on the 43rd Avenue corridor would equal approximately 4 peak hour trips. Even if the route were operated at one-half hour headways, the TDP analysis indicates that the route would not carry nearly enough riders to mitigate sufficient trips to maintain level of service "D" on 43rd Avenue. o Level of Service Alternatives Given the absence of viable roadway or transit alternatives in the 43rd Avenue/27th Avenue corridor, the county adopted Level of Service `B" plus 20% as the minimum acceptable level of service standard for the following roadways: - 27th Avenue — South County Line to SR 60 - 43rd Avenue — Oslo Road to 16th Street Since that decision, a subsequent analysis determined that a four lane section (as opposed to the original five -lanes) on these roadways would enable the county to maintain its LOS "D" standard while minimizing the impacts to surrounding properties. Consequently, both 27th and 43rd Avenues have been programmed for improvement to four -lane divided facilities. Therefore, the adopted level of service standard of "E+20%" for 27th and 43rd Avenues can be changed back to level of service "D" when these roadways are in the first three years of the county's capital improvement program. Since 27th and 43rd Avenues are arterial roadways with strategic countywide and regional significance, the county should construct these roadways as four -lane divided facilities and restore the countywide adopted level of service of "D" to these facilities. • Intersection Analysis Even after all 2030 LRTP improvements are constructed in Indian River County, a small number of corridors will exceed their adopted levels of service. To address this issue, the MPO identified corridors with v/c ratios in the range of 0.98 and 1.2 for additional analysis to determine if any corridor improvements, other than widening, could improve level of service. Since signals are almost always the constraint points in urban area corridors, improvements to intersections within constrained corridors can sometimes mitigate congestion within the corridor. Potentially congested intersection locations include: - SR AlA @ 17th Street - US 1 (Sebastian) @: Barber Street Schumann Drive CR512 - SR 60 @: Community Development Department Indian River County 71
