The conceptual infrastructure design concepts aim to provide a safe and efficient road environment for all type of road users, and sustainable features to reduce the environmental impact of the impermeable surface in the future. The proposal aims to increase the awareness of future mobility change, the design concepts provide strategies to adapt to future mobility needs. Besides infrastructure design, it also proposes a connect mobility network wayfinding system to offer convenience for visitors and road users to effectively reach the destinations.

Infrastructure Design Key components:

- Travel Lane: The reduced width travel lanes in the urban environment to reduce vehicle driving speed;

- Regular Parking Zone: On street parking are still preserved for automobiles.

- Protected Bike Lane: The buffered bike lane provides flexible car door opening space and a safe buffer for cyclists.

- AVs Zone: Off traffic loading and unloading zone for AVs provide non-interference AV stop 

Mobility Network components:

Wayfinding Kiosk: The kiosk provides local mobility network information and key local destinations' information. The information will provide real-time transit connection information and information on optional travel mode, such as bike-share, ride-hailing, e-scooter, etc.

Sustainable Infrastructure:

Stormwater filtration Pond: On-street stormwater filtration ponds reduces the stormwater surface runoff and risks of sewage overflow.

Other possible feature:

Ride-hailing Waiting Furniture: The furniture provides liveliness on the sidewalk and the rest places for pedestrians and riders.

Bike Share-Station: Close by bike share station provides convenient last mile travel option.

Note: the component arrangement would depend on the street section and surrounding urban context.

Describe who will use your solution (1,000 characters)

Conventional road users:
Driver, Cyclist, Pedestrian, Motorcycle Rider;
Potential road users:

Describe your solution's stage of development

  • Initial Design - you are still exploring the idea and have not tested it with users

Tell us about your team or organization (500 characters)

CitEMotion provides urban planning, design, and development consulting services for communities who dare to lead the future. The main goal of the company is to create evidence-based solutions for human-centered urban transformations.

Size of your team or organization

  • I am submitting as an individual

Funding Request

  • $75,000

Describe how you would pilot your idea (1000 characters)

The road infrastructure: The project would collaborate with the City of Pittsburgh, Department of City Planning and Department of Mobility and Infrastructure to select the most suitable location within the city to pilot project. Also, CitEMotion would works with contractors to modify the street infrastructure.
The mobility network kiosk: In addition to collecting information from the city departments for the digital mobility network. CitEMotion would work with key stakeholders around the selected location to input destination information into the wayfinding system.

Describe how you would measure the success of your pilot (1000 characters)

Besides the long-term improvement of urban flow which would be based on the measurement of a larger urban adaptation of the design concept, the success of the project would be based on the usage of the infrastructure and accident reduction.
Regarding infrastructure: The measurement could be performed through traffic counts, including automobile, bicycle, pedestrian, etc., the counts would be used as a measurement to compare with the historical traffic flow data to see the traffic change. Additionally, the project could track the accidents to measure the road environment safety.
Regarding wayfinding kiosk: Similarly, it would be based on the usage of the information look up.
User feedback: The project would also record the feedback from general users to perform user study on what would be the possible improvement field.

Hi Lu, thank you for the submission I am one of the facilitators on the platform. I like that your idea addresses the possibility of bringing together existing mobility services and information in one place. However, would the AV staging area need to be on the other side of the bike lane? Having vehicles cross the lane may make some cyclists uncomfortable, so perhaps similar to some bus stop designs the area could be more aligned to the road with the lane behind it.

Dear Idrees, thank you for the comment. The crossing would definitely create uncomfortableness for cyclists and shifting the bike travel zone back to the vehicular on-off area make sense as well, but it would also create a crossing zone for pedestrians... (Lets excluding the shared pedestrian and bicycle sidewalk at the moment, as major US cities haven't adapted to mixed traffic norm yet.) My design concept is still in exploration, I believe many different design scenarios would make sense in relative urban street contexts, like the one you imagined that some streets may have to separate staging area from non-vehicular travel mode but some other may make sense to bring the staging area close the curb like areas around major commercial destinations or bar streets... Most importantly, I hope to use this opportunity to increase the awareness of the need for urban infrastructure updates for semi-autonomous travel, and possibly, we could try a few temporary installations to test and record the data to see what type of street design would help the adaptation of AVs and improve urban mobility. Thank you again, I can revise some of my writing to make it clear.

No problem Lu, thank you for the response! If you would like to make changes you can always update your proposal between now and the end of the propose phase.
