Westlake Avenue North Existing Conditions Study
October 3, 2013
To inform the concept development process, the project team is studying existing conditions. This first step completes a topographical survey, traffic data collection and a parking utilization study. Initial design and alternative evaluation follows this effort. This research got underway in August and September of 2013 and final analysis will be posted here, once complete. The study area is from Aloha Street (Lake Union Park) to just north of Halladay Street, at the start of the Ship Canal Trail.
Parking Utilization Study
East side of Westlake Corridor parking lot
The project team is analyzing the following data, collected for each block and the City-owned parking lot in the study area:
In addition, the study will be supplemented with information from the most recent City annual paid parking study.
Traffic Data Collection
Westlake Corridor parking lot at Galer Street
The team collected traffic data in September 2013 will be collected to quantify the existing conditions within the corridor including bicycle, pedestrian, and vehicles counts at driveway intersection with Westlake Avenue and along the existing sidewalk. The counts were done utilizing video collection, including a video analysis to document behaviors, interactions and conflicts between users. Bicycle and pedestrian counts were collected at three (3) locations within the corridor: the street, the parking lot and the internal sidewalk on the east side of the parking lots.
Turning movement counts were collected at 14 locations targeting driveways connecting Westlake Avenue to the parking lots. Turning movements into and out of the parking lot driveways, the first internal intersection and the service drive were recorded. These counts do not include through movements on Westlake Avenue.
Video analysis was completed at four (4) locations targeting locations within the parking lots identified during the field assessments. All data will be reviewed to document parking lot traffic flow, circulation patterns, user behavior, and actual or potential multi-modal conflicts.
