Traffic counts and design details: consultant says lanes will narrow travel lanes to calm speeds
Summary
Dynamic Traffic presented counts, speeds and crash history for Parker Avenue and proposed a consistent cross-section: 10-foot travel lanes and 5–7-foot bike lanes, with green markings and targeted shared-lane treatment where parking demand exists.
Pat Downey of Dynamic Traffic summarized the corridor analysis and explained how the proposed striping and markings respond to observed conditions: "we performed traffic counts and found, an average daily traffic volume ranging between 5 to 7500 vehicles per day," he said, noting 85th-percentile speeds up to 34 mph and that about 7% of crashes over the analyzed period involved pedestrians or cyclists. Downey said the eastern study reach is one of the wider sections (about 34 feet cartway) and that most of the corridor could be configured with 10-foot travel lanes and 5–7-foot bike lanes, but one block with high parking demand would use a shared-lane (sharrow) transition.
Downey described parking-utilization mapping and a constrained block east of Boynton that retains striping for parking and merges the bike lane into the travel lane there; he said enhanced green markings would be used at major intersections and that the design aims to improve sight lines, crosswalk visibility, and bicycle/pedestrian safety without full roadway widening.
