Ventura County proposes new bike lane design using K71 bollards and concrete barriers

The Traffic and Transportation Advisory Commission meeting held on March 26, 2025, in Thousand Oaks, Ventura County, focused on the implementation of new safety measures for cyclists and motorists along key roadways. The discussions highlighted various options for enhancing bike lane infrastructure, with a strong emphasis on safety and accessibility.

One of the primary topics was the use of flexible delineators, which are economical and easy to install. These delineators allow for emergency vehicle access but require frequent replacement due to their vulnerability to damage. Rumble strips were also considered; while they are low-cost and provide sensory alerts to distracted drivers, they were rejected by the Bicycle Advisory Team due to concerns about noise and their impact on cyclists.

The commission discussed K71 and K72 bollards, which are favored for their effectiveness in separating vehicles from bicycles. These bollards can withstand high-speed impacts and are designed for easy maintenance. The K72 bollards, while slightly more expensive, offer a more substantial visual barrier and are recommended for use in the city’s bike lane projects.

The meeting also addressed the use of precast concrete barriers, which provide continuous separation but limit access for emergency and maintenance vehicles. The commission recommended using these barriers at the Lynn Road and US 101 Overcross, as they meet Caltrans specifications for safety.

Commissioners expressed enthusiasm for the project, noting its potential to encourage cycling in the community. Questions arose regarding the safety perceptions of different barrier types, with a focus on ensuring that cyclists feel secure while navigating busy intersections. The design aims to maintain existing vehicular traffic flow without requiring adjustments to traffic signals.

In conclusion, the meeting underscored the city’s commitment to improving cycling infrastructure while balancing safety and accessibility for all road users. The recommendations will be further evaluated as the project progresses, with an eye toward future funding for additional enhancements, including sidewalks. The commission's proactive approach reflects a growing recognition of the importance of safe cycling routes in urban planning.
