What this is about
An array of artifacts I did while working on roads/highways tools for Autodesk Infraworks. This was early in my career and I was given a lot of creative freedom and flexibility.

Autodesk Infraworks, ca. 2013
About Autodesk Infraworks
Autodesk Infraworks helps transportation planners, urban planners, and civil engineers design all aspects of a city layout in order to share plans with stakeholders (e.g., city councils and local citizens, police, private developers) and visualize proposed infrastructure updates. Engineers can import GIS data or an existing map, view it in 3D, edit elements within the drawing canvas, and export specific views to share with stakeholders.
Conceptual design: learning concepts via sketching
A "comic" to help myself understand the steps in the conceptual design phase of infrastructure design—what our software targeted.
Fun Fact: This scenario was based loosely off a real-life proposal to find a location for the first Starbucks in Waltham, MA. It was cool that there was a real-world example a half-mile from our office!

Lightweight comic that captures the stakeholders, issues, and steps that go into a typical conceptual design workflow.
A couple of sketches of different turn lane configurations as I was learning them:

Sketching numerous left-turn setups.

And right-turn setups.
Beginning to delve into interchanges...

Examining highway/expressway interchanges in terms of layers. This was a visual experiment, to consider how to break up an interchange into components that could be configured/edited. The layers aren't necessarily meant to be top-to-bottom (which of the three would be on top, right?), but I was exploring the basic idea of breaking this into 3 parts.

Color-coding components of a cloverleaf interchange, to identify areas with different properties that might need different editing configurations.
Storyboard-style wireframes
Mocking up three interaction styles in order to create and edit intersections "in-canvas" (in the context of the visual Infraworks UI).
You can download the full PDF to click through them and watch them animate.

Illustrations: design vehicles
These are the largest vehicle that a road is designed to accommodate, either due to construction materials used or just sheer size/dimensions.
I did a series of vector illustrations of the design vehicles, which users could then choose from a palette. They were still in the product as of a few years ago! I could do a more refined job today, but I'm still quite proud of them. :)
