<br /> <br />Page 6 <br />Proposal for Engineering & Traffic Survey for Speed Limits Update - RFP No. 21-002 <br /> <br />The field survey data will be marked on a radar speed survey field sheet similar to the City <br />supplied sample in the RFP with the following additional roadway segment information: <br /> <br />• Adjacent land use types • Lane configuration <br />• Roadway geometrics • Median type <br />• On-Street Parking • No Parking/Stopping restrictions <br />• School Zone • Truck Route <br />• Bike Route • Bike lane facilities <br />• Pedestrian and bicycle activity • General Comments <br /> <br />A sample of the radar speed survey field sheet is provided in Appendix C. The final format of <br />the field survey data sheet will be pre-approved by the City. <br /> <br />If the collected speed survey data are unusually high or low, AGA will conduct up to twelve (12) <br />radar speed resurveys at the same segment locations at no cost to the City. <br /> <br />AGA will also collect the posted speed limit information for adjacent jurisdictions (e.g., the Cities <br />of Costa Mesa, Irvine, Tustin, Orange, Garden Grove, and Fountain Valley), with roadway <br />segments abutting or under joint control with the City of Santa Ana. <br /> <br />Task 2 – Speed Data Analysis <br /> <br />AGA will enter the field survey data into a speed survey data worksheet to determine the <br />following speed data analytics: <br /> <br />• 85th Percentile speed <br />• 50th Percentile speed <br />• 15th Percentile speed <br />• Average Speed <br />• 10 mph pace speed <br />• Percent in pace speed <br />• Percent over pace speed <br />• Percent under pace speed <br /> <br />A sample of the radar speed survey data worksheet is provided in Appendix D. The final format <br />of the worksheet will be pre-approved by the City. <br /> <br />Task 3 – Roadway Segment Characteristics Review <br /> <br />A licensed Traffic Engineer will review all of the street segments to determine any roadway <br />conditions not readily apparent to the motorist which would justify lowering the proposed speed <br />limit to the maximum reduction permitted under the State established guidelines. These <br />characteristics include the following: <br /> <br />• Street width and alignment • Traffic flow characteristics <br />• Channelization and striping patterns • Frequency of driveways <br />• Reversed super elevation • Visibility obstructions <br />• Roadside land use • Roadway grade <br />• Heavy pedestrians and/or trucks • On-street parking <br /> <br />City Council 17 –48 10/19/2021
