The Changemakers Guide to Walkable & Bikeable Cities

 

“If you can change the street, you can change the world.” Janette Sadik Khan

At Miovision, our mission is to use technology to improve the transportation experience for everyone. Over the past few months, we’ve been hard at work putting together the Changemaker’s Guide to Walkable and Bikeable Cities. Why? Because we want to empower transportation professionals to transform their streets. This guide will act as a fully-stocked toolkit for transportation professionals and government officials looking to build bike-friendly and walkable cities.

It’s Time to Rethink Cities

For too long cities have prioritized cars over people. More roads, more traffic, and lower levels of health are all symptoms of the broken city. Transportation engineers are forced to use outdated metrics. Public planners are handcuffed by layers of red tape and analysis for pedestrian-friendly projects.

The change needed is already on its way. Cities across North America are recognizing that citizens of walkable and bikeable cities are healthier, wealthier and happier. We’re experiencing it first hand at Miovision, with our technology already being used for major bike lane projects.

A Call to Changemakers

If you’re reading this, chances are you’re looking to challenge the status quo too. Our Changemaker’s Guide will help you get there. It’s a one-stop reference point that we update regularly, packed with information including:

  1. Benefits of Walkable and Bikeable Cities
  2. Strategies to Influencing Change
  3. Planning Resources
  4. Data Collection Strategies
  5. Implementation Tips
  6. Success Stories

Get Started. Get Involved.

This movement is more than just a guide. It’s about working together to make change happen. Here are a few other ways to get started:

  1. Download our Changemaker’s Toolkit, a collection of resources and tidbits from our guide consolidated into a single PDF.
  2. Share your story and inspire others. If you’ve made your town or city more walkable or bikeable, let us know! We’ll spotlight you in our guide.

Miovision hopes this guide will support you on your journey to make a better city or town. Don’t simply be a passenger in the journey towards sustainable transportation models, make yourself a driver of change.

Help Miovision make transportation better for everyone.

Turning Video into Traffic Data Part Two

In Turning Video into Traffic Data Part One, I wrote about Miovision’s systematic method for processing the large amount of video that is uploaded to our system. I detailed our three step process for video configuration, quality assurance, and data validation, and explained how computer vision is used to detect vehicle movements from video. If you haven’t yet read Part One, I would recommend you start there.

In this second-and-final post, I will be diving into the details of data accuracy, how we account for error, how we develop our best-in-class algorithm, and how that helps our customers rely on the quality of Miovision data for any project of any size.

Deconstructing a Frame of Video into Spatial Regions for Counting

When video is uploaded to Miovision, cardinal direction and number of lanes are required inputs. That is because each video is split into video segments to be processed individually.

Each video segment is determined by spatial region, lane and approach. Segments are then  distributed through a number of processes on a cloud computing service and queued for distribution to a computer vision task.

When computer vision tasks are complete, each video segment is queued for human review and verification. Humans manually count a 12% cross-section from each hour of video to ensure that the computer vision algorithm is properly producing counts and the data is accurate.

annotating an intersection

Screenshot: When the customer uploads a video to the Miovision Platform, they are required to annotate each leg of the intersection (or other road facility) and denote the camera position in relation to vehicle movements. This ensures proper configuration, and this metadata is stored with the count data and video for posterity. The annotation provided in this step is then deconstructed one step further at Miovision and made into counting tasks.

Turning Video into Traffic Data Part One

As of this spring, Miovision will have turned 1.5 million hours of video into traffic data from multiple video sources, including our own Scout Video Collection Unit. With daily volumes as high as 7,000 hours of video, we rely on a systematic method of combining computer vision algorithms  and human verification to ensure data reports meet our customers’ expectations.

In this two-part blog series, I’ll be writing about how Miovision turns video into traffic data with significant support from Miovision Technical Director and Computer Vision Architect Justin Eichel, PhD.

Video-Based Traffic Data Collection

For those not familiar with Miovision’s traffic data collection solution, here’s a quick overview:

  1. Customer records video: this can be of an intersection, midblock, highway count, roundabout or pedestrian and bicycle location. Video can be provided by any video source, but we recommend our best-in-class Scout video collection unit.
  2. Video is uploaded to Miovision: every customer has a cloud-based account on the Miovision Platform where they can upload video and quickly select the types and amount of data they need.
  3. Data Reports are Downloaded: the video is turned into traffic data on the Miovision Platform. Data reports are stored on the customer account and available for download in a variety of formats, along with the video recording.
