EXHIBIT A SCOPE OF SERVICES ______________________________________________________________________________ Consulting Services Agreement between City of San Leandro and 9/1/2023 W-Trans for Citywide Engineering and Traffic Survey Page 2 of 3 measuring devices will be used to measure the unimpeded speed of free-flowing vehicles. While taking the speed measurements, traffic speeds will not be altered by law enforcement, the surveyor and equipment, or any other means. The time of data collection will be scheduled to avoid the City’s Paving and Street sealing projects so that the most accurate data is collected. The calibration certificates for any radar guns to be used in the data collection effort will be submitted for the City’s records. 2.4 All machine counts, radar speed surveys and field observations will occur during October 2023. 2.5 Raw crash records for each roadway segment for at least the most recent 3-year period will be provided by the City though their Crossroads database. 3.0 Evaluation 3.1 All pertinent information will be entered in a Microsoft Excel spreadsheet form. W-Trans has developed a form that provides detailed information regarding all the data that is utilized in determining appropriate speed limits, including all the information required per the guidelines in the most recent edition of the California Manual on Uniform Traffic Control Devices (CA-MUTCD), as well as other relevant information such as adjacent speed limits (if different), sight distance issues, and other conditions “not readily apparent” to drivers. A sample form from recent work for the City of San Carlos is provided in Appendix B. 3.2 In accordance with the CVC and CA-MUTCD, speed limit recommendations will be based on speed survey data and calculated required parameters such as average speed, critical speed, and pace speed. Recommended speed limits will be established at the nearest 5-mph increment of the 85th percentile speed of free-flowing traffic, except as indicated in the two options below: 1. The posted speed may be reduced by 5 mph from the nearest 5-mph increment of the 85th-percentile speed, in compliance with CVC Sections 627 and 22358.5. See Standard below for documentation requirements. 2. For cases in which the nearest 5-mph increment of the 85th-percentile speed would require a rounding up, then the speed limit may be rounded down to the nearest 5 mph increment below the 85th- percentile speed, if no further reduction is used. Refer to CVC Section 21400(b). 2.6 Prior to initiating work on the draft report, a conference call will be initiated to discuss any recommended changes from the existing speed limits and to obtain local insight which might affect the recommendations. It would be at this point that segments would be re-surveyed, if desired, and the new survey data inserted in the appropriate forms. 2.7 Summary sheets showing bi-directional machine traffic volume data, radar speed survey data and speed limit recommendations will be provided to City staff review and approval. Sheets containing the raw count and speed survey data will also be provided showing speed profile histograms and cumulative speed profile curves for each speed survey zone.
