The Chittenden County Regional Planning Commission has measured the usage of North Avenue to get a good baseline to compare to the pilot implementation. These metrics include vehicle, pedestrian, and bicycle counts, traffic speeds, parking utilization, wait times, transit times, public transit operations, emergency vehicle operations, traffic violations, business impacts, crashes, and school drop off data.
Data collected by CCRPC:
- Summer 2015 vehicle volumes and speeds
- Summer 2015 pedestrian and bicycle counts at intersections
- Travel times
- Parking utilization
Final evaluation of the pilot will include comparisons to baseline measurements as well as public input.
The simulations below are models based on today’s AM and PM peak hour traffic volumes (note: volumes were collected while schools were in session). Vehicles are color coded based on their upcoming turning movement. Their color will change as they pass through an intersection if their next turn is different than that of the previous. For example, a North Avenue northbound through vehicle at the VT 127 intersection whose next turn is a right at Ethan Allen Parkway will change from white to yellow as it passes through the intersection. White vehicles will travel straight through the next intersection, light blue vehicles will turn left, and yellow vehicles will turn right. Green vehicles are those that have reached the end of the model. You will also see dark blue cars that disappear. This is how the model handles vehicles turning into driveways or side streets that are not individually modeled. Relatedly, you may also see vehicles appear seemingly out of nowhere which is how the model accounts for vehicles entering North Avenue from driveways or side streets.
The morning commute video seen below simulates traffic volumes that use North Avenue between 7:30 and 8:00 AM.
The evening commute video seen below simulates traffic volumes that use North Avenue between 4:45 and 5:15 PM.
This model is only used for simulation and traffic analysis purposes. Locations of striping, turn lanes, traffic signals, and streets are approximate and in some cases limited by the software. Specifically, Little Eagle Bay is shown to align properly with Ethan Allen Parkway and have a traffic signal for its approach. This was necessary in order to incorporate Little Eagle Bay into the five-way intersection. Neither realignment of Little Eagle Bay nor signalization are part of the pilot study. While realignment has not been explored, signalization of this approach is a recommendation that came out of the North Avenue Corridor Study.
