How To: Use Scoring Configuration with DeepWalk

Introduction

0:00 Hello, this is Yu-Ning Liu. I am a GIS engineer at DeepWalk. In this tutorial, we will walk you through the scoring configuration, which is a new feature that lets you customize how the sidewalk accessibility score is evaluated and is calculated based on your project's priority.

What is the Sidewalk Scoring?

0:22 DeepWalk's scoring system evaluate the sidewalk conditions based on the key ADA aligns, factor like the cross slope, the clear width, the run slope, deterioration, and the ramp presence.

0:38 We have already developed the accessibility score. The existing sidewalk grading algorithm, you can see it more details on our website.

0:47 But now, with the scoring configuration system, you will be have the ability to adjust how much each factor impacts the overall accessibility score, making your evaluations more tailored and actionable to your project.

How to Set Up Scoring Configuration with DeepWalk?

1:06 So here is how to set it up. To configure the scoring in the web app, please start by navigating to the portal and go to the option settings, and you will see the project tab, and there is a scoring configuration section.

1:28 Please choose to create new, scoring configuration, and for example, name the new configuration. Go to the setting here, and here you will start to customize how different sidewalk conditions influence the final accessibility score.

1:48 So you can see, we basically have three different three parts of the setup. First is general settings, including the weight assigned to the percentage of the deteriorated sidewalk area and the accessibility grades applied for the steps or the stairs' existence.

2:08 These settings will help capture overall sidewalk conditions. So if I choose the light*, grade being 2, for those general condition setups.

2:27 Next, we can also configure scoring based on the sidewalk type. Uh, we have currently the mid-block and the ramp sidewalk.

2:36 For the mid-block, you can set the adjustable threshold for the cross slope, the run slope, and the clear width. Also, these factors determine the walkability along the continuous sidewalk segments.

2:51 You can also set it. You can  assign the weight for individual measurements.

2:58 There is one optional selection where You can choose to ignore the run slope if you are more focused on other measurements. So, if we can set up, like, 10 being extreme, uh, for the cross slope, ignore the run slope, and clear with should be fine like, wider than 42, and being minor for the width ranging from 40 to 42. We can select moderate or light for this measurement as well.

3:38 The other sidewalks type is ramp. You will see the basically same setup with threshold, parameters you can tweak, but also you'll have additional options to adjust the grade impact for the missing ramp and the weight for detectable warning surfaces, so to ensure the crossings meet the ADA standard.

4:08 We can choose the model. For example, for the missing detectable warning, we can choose; Maybe keep it 2 for any missing ramps that are found.

4:22 You can also enable the customized manual tags to reflect the site specific issue. For example, we can activate like the presence factor to include the trip hazard.

4:36 And also set up the score weight for the trip hazard tags. This is also one of the most frequently used manual tags among our customers.

4:47 Other common manual tasks also include like the joint spalling or the tree hazard. So if you add tag, under the Data Collection > Tags page, you will see the tags listed here, so you can try to enable or disable these tags to be included in the scoring calculation process.

Run Customized Scoring

5:15 Once your configuration is complete, you can save it, and you can return to the Home page.

5:27 On the site menu, you will see a dropdown labeled scoring configuration. From this dropdown, you can select the configuration you just created.

5:38 You can see the app will apply your customized scoring settings to the entire project. Depending on the size of the project, the calculation process may take a few minutes to complete.

5:53 You'll see the average accessibility score displayed on here, on the Home page reflects the overall accessibility of the entire sidewalk network based on your customized configuration.

6:04 But what is really great about this feature is that when you select a different score and configuration, from the dropdown, you will see how the accessibility score changes based on the new settings.

Why Customize Scoring?

6:22 Customizing your scoring configuration allows you to tailor sidewalk evaluation to match the specific goals and prioritize your projects. Whether you are focusing on, for example, the ramp, accessibility, or trip hazard, or other critical condition adjusting the weight of each factors will ensure that the final score reflects what matters most to you.

6:49 For example, if your sidewalk project emphasizes ramp accessibility, you can increase the weight of the missing detectable-warning*, or, assigning the highest grade impact on the overall score for the missing ramp.

7:07 You can ensure the issue that have a greater impact on the overall score. So, it will help pinpoint the critical gaps in accessibility, especially in the areas where the ramps and the detectable warning are absent.

7:24 Ultimately, the customized score configuration will provide you a more detailed and accurate understanding of the sidewalk conditions.

7:36 It will help you to make the data-driven decision, and prioritize the repairs where they are needed most.

Closing

7:47 To wrap up, our scoring config gives you the complete control of how the accessibility is assessed and prioritized, and to ensure your project goals to shape every evaluation.
