INSIGHTS
The Infrastructure Systems Insights through Geospatial-sensing for Holistic Transportation Solutions (INSIGHTS) project is ARPA-I's first step towards enabling development of practical, cost-effective, continuously updated digital models of America's infrastructure at scale, including streets, highways, ports, rail lines, airports, and pipelines.
ARPA-I INSIGHTSX-BRIDGE
The ARPA-I eXceptional Bridges through Innovative Design and Groundbreaking Engineering (X-BRIDGE) program is focused on creating transformative materials, designs, and construction techniques that can deliver bridges at half the cost, in half the time, and with twice the lifespan.
ARPA-I X-BRIDGEWhat Are the Heilmeier Questions?
At ARPA-I, we leverage the Heilmeier Catechism to assess and think through proposed research programs.
- What are you trying to do? Articulate your objectives using absolutely no jargon.
- How is it done today, and what are the limits of current practice?
- What is new in your approach and why do you think it will be successful?
- Who cares? If you are successful, what difference will it make?
- What are the risks?
- How much will it cost?
- How long will it take?
- What are the mid-term and final “exams” to check for success?
