During a recent government meeting, officials discussed the proposed design and implications of a new roundabout aimed at improving traffic flow on Alameda Avenue. The roundabout's configuration was a focal point, with suggestions made to consider alternative shapes, such as ovals, to enhance functionality. Concerns were raised about left turn restrictions for southbound traffic, which could lead to increased congestion on Atherton Avenue, potentially disadvantaging its residents compared to those on adjacent streets.
The feasibility analysis presented indicated that the optimal diameter for the roundabout would be 90 feet, accommodating the daily traffic volume of approximately 16,000 to 17,000 vehicles. The design includes a shared-use travel lane of 12 feet and a truck apron to facilitate larger vehicles, ensuring safety and efficiency in traffic movement.
Officials emphasized the safety benefits of roundabouts over traditional traffic lights, noting that they could significantly reduce accident rates. However, questions arose regarding the adequacy of the design for emergency vehicles, prompting a commitment to consult with the fire department to ensure compliance with their operational requirements.
Visual aids were utilized to illustrate the proposed roundabout, which features splitter islands and crosswalks, enhancing pedestrian safety. The meeting concluded with a consensus on the importance of further consultations with relevant stakeholders, including emergency services, to refine the design before final approval.
