BACKGROUND: DATA: In February, staff was asked to study the Carlsbad Boulevard/Oak Avenue intersection. Collision history, vehicle counts and turn movement data was reviewed. Following this investigation, a STOP sign warrant analysis and traffic signal warrant analysis was conducted. The traffic signal analysis indicates that two of the eleven warrants described in the Caltrans Traffic Manual have been met. Carlsbad Boulevard is classified as a major arterial. The roadway is 82' wide and provides two lanes in each direction and left turn lanes at the intersection. Oak Avenue is considered a local street. Oak Avenue is 40' wide and provides for one lane in each direction. Both roads are fully improved. Parking on Carlsbad Boulevard is limited to the east side of the street, northerly and southerly of this intersection. Parking is provided on both sides of Oak Avenue. Carlsbad Boulevard has a slight curvilinear alignment and vertical grade at this location and Oak Avenue has a slight grade (vertically) on each approach to this intersection. The existing traffic controls are STOP signs, limit lines and pavement legends on Oak Avenue with no controls provided on Carlsbad Boulevard. Recent two-way traffic volumes are 18,588 ADT on Carlsbad Boulevard and 1,262 ADT on Oak Avenue. The collision history for the past five years indicate seven reported collisions. The collision diagrams are attached to this report, as Exhibits 3-8. Of the seven reported collisions, two were of the type that would typically be corrected by installation of a traffic signal.
