TC - Item 3A - Traffic Review of the Northwest Curb Ramp at the Intersection of Garvey Avenue and Bartlett AvenueTRANSTEch TO: City of Rosemead, Department of Public Works FROM: Traffic Engineering, Transtech Engineers, Inc. DATE: January 18, 2022 SUBJECT: Traffic Review of the NW Curb Ramp at the Intersection of Garvey Avenue and Bartlett Avenue IILlY1To]111111d M l The City of Rosemead received a resident request to evaluate the existing driveway access and curb ramp adjacent to the Wilson Complete Auto Repair shop, located at 8689 Garvey Avenue, at the northwest corner of Garvey Avenue and Bartlett Avenue. In response to this request and on behalf of the City, engineering staff has completed a traffic review of this location. The resident reported that drivers sometimes access the shop via the curb ramp and drive over the curb ramp thinking it is a driveway; appropriate improvements have been recommended to provide more visibility to the curb ramp indicating it is not a driveway and to deter vehicles from using it as such. The recommendations include installation of yellow railings behind the curb ramp and installation of red curb markings. The traffic review included an analysis of the existing roadway conditions, a review of approximately 5.5 years of available collision data, and an examination of the existing field conditions.

Collision data was obtained from the computerized collision records system maintained by the State of California called the Statewide Integrated Traffic Records Systems (SWITRS). An analysis was conducted of available collisions that were reported to SWITRS and that occurred within 250 -feet of the subject intersection of Garvey Avenue and Bartlett Avenue. The collision analysis was conducted over approximately a 5.5 -year period between January 2016 through October 2021 (available data at the time of traffic review). Based on the information provided, a summary breakdown of the number of collisions within the studied segment are listed below and shown in Table 1.

According to the SWITRS reports 1 of the collisions involved a pedestrian. It is unclear from the available collision data if any collisions were a direct result of vehicles using the NW ramp for access to the business.

I Page 6 of 9 Traffic Review of the NW Curb Ramp at the Intersection of Garvey Avenue and Bartlett Avenue Figure 3: Collision Diagram, Intersection of Garvey Avenue and Bartlett Avenue HANDRAIL INSTALLATION Caltrans has provided a Detail for the construction of a fence or handrail on the curb behind the wheel chair ramp. A handrail is provided to channel pedestrians to the sloping ramp that provide the greatest level of safety instead of crossing from behind the ramp. In this instance it will also aid in discouraging vehicles from using the ramp as an entry point to the garage behind it or to park overhanging into the ramp. Figure 4 below provides a detail of a handrail installation. Caltrans Standard Plans for Construction, Detail B, is a diagram of the standard set by Caltrans for handrail installation behind curb ramps. O E., ..A.__,.

I Page 7 of 9 Traffic Review of the NW Curb Ramp at the Intersection of Garvey Avenue and Bartlett Avenue RECOMMENDATIONS After a thorough review of existing field and traffic conditions and per the guidelines in the California Manual on Uniform Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), and based on engineering judgement, it was determined that the intersection of Garvey Avenue and Bartlett Avenue would benefit from the installation of yellow railings along the outside of the ADA curb ramp on the northwest corner of the intersection. As well as red curb as further reinforcement of no parking areas. The railing installation should be similar to the yellow railing installed at the intersection of Ramona Boulevard and Burton Avenue. Please refer to Figure 5 for a sample of the existing yellow railing installation at the southwest corner of Ramona Boulevard and Burton Avenue behind the curb ramp in the City of Rosemead. The handrail at this location is channeling pedestrians to the sidewalk and ramp and also serves to prevent cars from parking too close to the curb. Please refer to Figure 6 for a conceptual representation of the proposed yellow railing installation at the northwest corner of the intersection of Garvey Avenue and Bartlett Avenue behind the curb ramp.
