Carla Easton, P.E. City Engineer & Community Development Director February 6, 2020 SUMMARY OF TRAFFIC REGULATIONS AND DESIGN RECOMMENDATIONS REGARDING INSTALLATION OF STOP SIGN AT STONE AVE BACKGROUND: A request to install a traffic stop sign on Stone Avenue at the eastbound approach to Lewis Lane was presented to the Traffic Commission on 2/4/2020 by Ms. Jennifer Morgan. She expressed her concern for drivers having difficulty entering the North Lamar campus from Stone Avenue when approaching the T- intersection northbound on Lewis Lane. Her reasoning was that high traffic volumes entering the school from Stone Ave during the morning and afternoon school rush make it difficult to enter the intersection from Lewis Ln. She prefers that traffic on Stone stop to accommodate a turn from the side street. ■ Stone Ave is the higher priority street with the through movement, and provides direct access to the NLISD campus, hospital campus and emergency room ■ Lewis Ln dead ends at Stone, creating a T -intersection ■ Panther Drive is a private road providing access to schools on the NLISD campus ■ State traffic law requires traffic approaching from the side street of an uncontrolled T - intersection to stop then yield to the through movement ■ When it is determined that an intersection needs to be controlled with traffic devices, there are guidelines provided by the Texas Manual on Uniform Traffic Control Devices (TMUTCD) ■ Compliance with the TMUTCD is important so that regulatory signs are installed in a manner that is familiar and consistent for drivers, otherwise they are ineffective ■ Compliance with TMUTCD also minimizes liability to the city in case of accidents resulting from unique or unexpected signage This intersection is complicated by the offset of Lewis Ln and Panther Drive. Stone Ave operates as the major street with Panther Drive and Lewis Ln being side streets creating 2 separate T -intersections within 160' of street.
