Accessibility Mapping Research

PhD research on using open data for inclusive urban mobility mapping

My PhD research in Geodetic Sciences at the Federal University of Paraná focuses on developing methodologies for accessibility mapping using open data sources and collaborative cartography approaches. This research addresses the critical need for comprehensive, up-to-date accessibility information to support inclusive urban planning and navigation.

Research Objectives

The primary goal is to establish systematic approaches for creating and maintaining detailed pedestrian accessibility datasets that can inform urban planning decisions and support accessible navigation applications. The research investigates how open data principles and crowdsourced mapping can democratize access to accessibility information.

Key Research Questions

  • How can open data sources be effectively integrated for comprehensive accessibility mapping?
  • What methodologies best support scalable, community-driven accessibility data collection?
  • How can we ensure data quality and consistency in crowdsourced accessibility mapping?
  • What are the most effective approaches for keeping accessibility data current and accurate?

Methodological Framework

This research contributes to the growing field of accessibility mapping and inclusive urban design, providing both theoretical frameworks and practical tools for creating more accessible cities.

Every project has a beautiful feature showcase page. It’s easy to include images in a flexible 3-column grid format. Make your photos 1/3, 2/3, or full width.

To give your project a background in the portfolio page, just add the img tag to the front matter like so:

---
layout: page
title: project
description: a project with a background image
img: /assets/img/12.jpg
---
Caption photos easily. On the left, a road goes through a tunnel. Middle, leaves artistically fall in a hipster photoshoot. Right, in another hipster photoshoot, a lumberjack grasps a handful of pine needles.
This image can also have a caption. It's like magic.

You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

You can also have artistically styled 2/3 + 1/3 images, like these.

The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

<div class="row justify-content-sm-center">
  <div class="col-sm-8 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/6.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
  <div class="col-sm-4 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/11.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
</div>
