2.0 Vehicular Safety The St. Johns County Annual Crash Report (2002) was used to evaluate crash rates along the corridor. The 2002 report was the most recent crash report available as of July 2004. The St. Johns County Annual Crash Report (2002) presents intersection crash rates for the 28 intersections countywide with the highest crash rates. The ratings reflect the application of a crash exposure rate, which takes into account roadway volumes. Of the top 28 intersections in the County with the highest crash rates, four are located along SR A1A. Crash Rate Ratio = Number of Crashes x 1,000,000/Average 24 hour total of entering

vehicles x 365 Source: St. Johns County, FL 2002 Annual Crash Report

• Motorists using the paved shoulder to pass vehicles stopped to turn left. • Permitting passing in the two-lane sections of SR A1A in areas where streets are closely

spaced. Specifically, the concern was raised in Vilano Beach near Surfside Park, where travelers turning right onto SR A1A from a local street find a vehicle passing a car on SR A1A in their travel lane, creating the potential of head on collisions.

Safety concerns identified above were voiced by residents during the Corridor Charrette. See Scenic and Historic A1A Master Plan: Appendix A – Charrette Reports.

During the Visual Preference Survey, residents voiced their concern over a bicycle facility as part of the shoulder. Residents believe that the proposed shoulders would increase speeding by visually widening the road. Furthermore, the existing bicycle facilities on the shoulder are perceived as unsafe for inexperienced bicyclists. Community concerns identified above were voiced by residents during the Corridor Charrette. See Scenic and Historic A1A Master Plan: Appendix A – Charrette Reports.

4.0 Speed Study As voiced at both the Corridor Charrette and the South Anastasia Island Charrette, the South Anastasia community is interested in reducing posted speeds to help reinforce safe driving behavior along SR A1A in South Anastasia Island. To evaluate the possibility or need to re-evaluate the posted speed limit, Glatting Jackson conducted spot speed studies in three locations in South Anastasia Island. The studies were conducted in accordance with FDOT Manual Number 750-010-002, Speed Zoning for Highways, Roads, and Streets in Florida. The spot speed studies were conducted on October 21, 2004. The study coincided with “Biketoberfest.” Therefore, there were a number of motorcyclists on the corridor. So as not to skew the results, a platoon of motorcyclists was counted as one vehicle, and not separate vehicles. Traffic was functioning at free flow conditions during the analysis period; therefore, the impact of the motorcyclists should be minimal. Along SR A1A south of the SR A1A/CR A1A intersection, the character of SR A1A changes based on the land uses types and densities it serves. For this analysis, the roadway has been classified into three categories based on land use types and densities. SR A1A has been categorized a Town Center around the 206 intersection, where the future land use map shows commercial development. This area also includes Crescent Beach Park and serves as a gateway to the Scenic Highway. SR A1A is categorized as a Community Street, between Green Street and the north boundary of Fort Matanzas National Park, where it provides regional mobility as well as direct access into residential homes and condominiums. SR A1A is categorized as rural in areas from the north boundary of Fort Matanzas National Park to the St. Johns County/Flagler County Line, where there are few access points, open views, and many undeveloped properties and publicly owned lands.

The large number of access points into single family residential lots, local streets, and large condominium complexes result in a large number of turning movements throughout the day. Turning vehicles will be traveling more slowly than vehicles traveling long distances. The difference in travel speeds may pose conflicts between the driver types (local vs. long distance). To evaluate travel characteristics in the Community Street area, a speed study was conducted along SR A1A south of SR 206 across from Crescent Sandpiper condominiums. The posted speed limit in this area is 55 mph.

Speed (MPH)

The above graphic shows there is a large dispersion of traveled speeds. 8% of vehicles travel under 40 mph. 77% of vehicles travel within the 10 mph pace (44 to 54 mph). 15% of vehicles travel between 55 and 65 mph.

Page 12: “Scenic and Historic A1A” Transportation Technical Report · 2011-08-26 · Bridge #780077 0.099 2009 Source: FDOT Web Site, August 4, 2004 A1A Scenic Highway St Johns County

A preliminary analysis of the 85th percentile speed at this location may lend to posting the speed at 55 mph. Further analysis of the broad dispersion of travel speeds and the number of access points on SR A1A suggest posting the speed limit lower. A 55 mph posted speed implies to the driver uninterrupted high speed travel, leading to frustration and dangerous passing when confronted with vehicles slowing to access homes. The highest travel speed, 65 mph, was clocked when a vehicle was passing another vehicle slowing to turn. While there are no standards directly linking posted speed limit to the number of access points, the Florida Department of Transportation does have guidelines that link the two.

35 mph or less – Special Case 125 35 mph or less 245 36 mph – 45 mph 440 Over 45 mph 660 SR A1A north of Vilano Town Center has land use characteristics similar to the area under consideration. This area is posted at 50 mph. The FDOT Manual Number 750-010-002, Speed Zoning for Highways, Roads, and Streets in Florida permits posting the speed limit up to 8 mph lower than the 85th percentile speed based on engineering judgment. For consistency along the corridor, to balance the demand for regional travel with the need for local access, and to reduce the speed distribution, it is recommended that the speed limit for the area south of SR A1A/CR A1A and north of Ft. Matanzas National Park currently posted 55 mph be updated to 50 mph. Rural Area There is a precedent for reducing the posted speed on bridges along and near the SR A1A corridor. The posted speed along SR 206 bridge over the Intracoastal approaching SR A1A is 40 mph. The posted speed along SR A1A on the Matanzas Bridge is 45 mph. This suggests that the two 500 foot bridges located north of the Town of Marineland, Bridge No. 780076 and Bridge No. 780077 commonly know as the Summer Haven Bridges, should also be posted at lower speed limits.

A speed study was conducted on the Matanzas Bridge and the northern Summer Haven bridge to evaluate current speed profile on the bridges. It should be noted that, as is a common occurrence, there were many people fishing off the Matanzas Bridge when the study was conducted. There was one individual fishing off of the northern Summer Haven bridge when the study was conducted. The presence of fishermen on the bridge, as well as drivers slowing to park on or near the bridge, may influence driving speeds, but since these conditions are typical they must be considered when defining the posted speed limit.

The FDOT Manual Number 750-010-002, Speed Zoning for Highways, Roads, and Streets in Florida permits posting the speed limit to be up to 8 mph lower than the 85th percentile speed based on engineering judgment. For consistency along the corridor and for the safety of fishermen accessing and using the Matanzas Bridge, it is recommended that the speed limit for the bridge be maintained at 45 mph and that the Summer Haven bridges be posted at 45 mph. Due to the proximity of the 45 mph zone north of the Town of Marineland and the spacing between the three bridges, it is recommended that the speed limit from the northern limit of the Town of Marineland to north of the Matanzas Bridge be posted at 45 mph.

5.0 Projected AADT This section outlines the process by which the forecast year (2024) projected peak hour vehicle trips were calculated for Scenic and Historic A1A from SR 312 to the Flagler County line for typical travel conditions. The forecast year (2024) peak hour vehicular trip projections were estimated by adding projected background growth, reserved capacity volumes and projected future development to existing traffic volumes. Existing Traffic Volumes The Florida Department of Transportation, Transportation Statistics Office collects traffic data using traffic counters at permanent and temporary traffic count stations around the state of Florida. These data are used to determine actual and estimated Florida traffic statistics like AADT (Annual Average Daily Traffic), and traffic adjustment factors. Within the study area, FDOT maintains five permanent count stations.

Trip Generation Associated with Potential Development on Vacant Land Vacant parcels were identified using GIS information provided by St. Johns County and verified using an aerial map for land located north of the St. Johns County/Flagler County line and south of SR 312 South Anastasia Island or Mid Anastasia Island. These sites are identified on the following map. While the map may not contain a completely comprehensive list of vacant or developable sites, it identifies an overall conceptual understanding of the land available for development on the islands. The following table presents the potential peak hour trips associated with development of the vacant parcels at maximum density permitted according to the St. Johns County 2015 Future Land Use Map. The following assumptions were made in distributing the trips onto the network:

• All trips originating from Link 134 will travel north along SR A1A, impacting Link 135.

• 30% of the trips originating from Link 134 and Link 135 will travel north of SR 206 along SR A1A, impacting Link 136 and Link 137.

• Half of the trips originating from Link 136 will travel north impacting Link 137. 10% of the trips originating from Link 136 will travel onto CR A1A, impacting Links 56 and 57. 10% of the trips originating from Link 136 will travel south, impacting Link 134 and Link 135.

• Half of the trips originating from Link 137 will travel south, impacting Link 136. 10% of the trips originating from Link 137 will travel south, impacting Link 134 and Link 135. 10% of the trips originating from Link 137 will travel onto CR A1A, impacting Links 56 and 57.

• All travel associated with development located east of CR A1A will load onto CR A1A. 30% of the development located west of CR A1A will load onto CR A1A. 60% of the development located west of CR A1A will load onto SR A1A through the local network. Of the development traffic that loads on CR A1A, 20% will travel south, impacting Links 136 and 137. 10% will continue south, impacting Links 134 and 135.

Projected Volumes The future volumes presented in the following table include background growth, vested trips, and potential development on vacant parcels. The projections are conservative in that they assume that all identified vacant lands will develop within the next twenty years. Furthermore, the increase in traffic associated with background growth would include all development that has occurred over the time period in which the counts were taken. Projecting these volumes and then adding future development may result in double counting a portion of the future trips, insuring a conservative estimate of future traffic on the corridor.

6.0 Roundabouts The Master Plan report recommends aesthetic treatments at major access points or decision points to the corridor, referred to as gateways to the corridor. Gateways introduce the driver to the scenic corridor and advise the traveler of the unique character of this destination. Corridor gateway opportunities have been identified at the following locations:

• The St. Johns County/Flagler County line, • Intersection of SR 206 and SR A1A, • Intersection of SR 312 and SR A1A, • Intersection of May Street and San Marco Avenue, and • The St. Johns County/Duval County line.

Local town or commercial centers are also served by gateways. Opportunity exists to introduce local gateways at those locations:

• St. Augustine Beach north entrance at Pope Road and CR A1A; and • Vilano Road and the Vilano Town Center, which is the historic route of SR A1A

through Vilano. A roundabout has been suggested for three of these gateway locations, the intersection of SR 206 and SR A1A, the intersection of Pope Road and CR A1A, and the intersection of SR A1A and Coastal Highway in Vilano, which present a unique opportunity of linking an aesthetic improvement with a roadway capacity and security enhancement. In addition, a roundabout has also been suggested at the entrance drive to the GTNMERR Educational Center. This section summarizes the potential vehicular benefits in reduced delay at these intersections by introducing a roundabout at these locations. Intersection of SR 206 and SR A1A Traffic counts were collected at the intersection of SR 206 and SR A1A during a two hour period between 4:00 PM and 6:00 PM on October 26-28, 2004. The raw counts are included in the appendix. 2024 traffic volumes were estimated by increasing the existing traffic counts by 86% for those vehicles traveling northbound from SR 206 or southbound from SR A1A and 67% for those vehicles traveling southbound from SR 206 or northbound from SR A1A.

A preliminary design of a possible roundabout at the intersection of SR A1A and Coastal Highway, Vilano is shown on the following page. The conceptual layout shows that there is sufficient right-of-way available to accommodate a roundabout in this location. Entrance to the Guana Tolomato Matanzas National Estuarine Research Reserve Environmental Education Center The Guana Tolomato Matanzas National Estuarine Research Reserve is constructing a major Environmental Education Center at Guana River State Park. The 20,000 sq. ft. GTM Reserve Environmental Education Center will contain two classrooms, a reference library, a teaching laboratory, a working wet laboratory, a aquariums, touch tanks, and an auditorium with full audio-visual capabilities that will seat 150+ people. The Design Team recommends that, if a traffic control device is required along SR A1A to provide adequate access to the Environmental Education Center, a roundabout be considered. A roundabout is more context appropriate than a signalized intersection since it does not introduce additional lights or mast arms to this rural site. Furthermore, a roundabout may be safer since it will not introduce a standing queue, which would not be anticipated by drivers in this rural location. The roundabout would also serve the additional purpose of providing a traffic calming element along this long, straight rural roadway section. Monitoring and analysis on trip generation and trip types attracted to the Environmental Education Center should be conducted before any decision is made on a traffic control device at this location.

7.0 Hurricane Evacuation The Northeast Florida Regional Planning Council completed a Hurricane Evacuation Study in 1998. The purpose of the study was to provide state and local emergency management officials the data needed to plan for protective actions for vulnerable areas in the event of a hurricane. Please see the full report for its findings, which include information on evacuation clearance times, shelter demands, demographics on the population to be evacuated, and use of places of refuge of last resort. Of interest for this project is the role of SR A1A in clearing residents from the islands during an evacuation. As part of the study, hurricane evacuation transportation modeling was performed. Modeling was conducted for Category 1 (minor) to Category 5 (major) hurricanes. Traffic Demand Model Assumptions • 100% participation from a county-scale evacuation area; • 25% of non-mobile home residents located out of the surge area were evacuated

during a category 3 hurricane or greater; • between 70% and 75% of vehicles available (1.82 vehicles per permanent unit in St.

Johns County) would be used to evacuate. Critical Segments Directional traffic service volumes at Level of Service D were established for each link included in the evacuation system. The Transportation Supplement document provides the assigned evacuating vehicle figures by roadway segment for each Year 2000 storm scenario by county. The document also provides an evacuation vehicles/service volume ratio for each roadway segment by scenario. The service volume ratio was used to identify critical segments, those roadways that control the flow of evacuation due to their congestion. No portion of SR A1A is considered a critical segment.

Source: Hurricane Evacuation Study 1998 Transportation Supplement Annex G – Evacuating Vehicle Trip Assignments by Roadway Segment by Storm Scenario By County The service volume ratios show that evacuation from the islands is limited by the capacity of the east-west connections across the Intracoastal: SR 206, SR 312, and CR 210 in St. Johns County and the Palm Coast Parkway to the south. The intersection of these east-west connections and US 1 also pose a capacity restraint for hurricane evacuations. Maximum Volumes per Link The Hurricane Evacuation Study presents a behavioral response curve (figure B-1, page B-9) that estimates a distribution of time for evacuees to leave their homes. Response time is plotted by the percent of the population that will leave their home over a ten hour period after an evacuation order is given, assuming long response, medium response, and rapid response by the community to the evacuation order. The table shows that during any response type, 10% of the population will respond before an evacuation order is given. This table can be used to estimate the volume of trips on a roadway during the peak period of evacuation.
