		<summary type="html">&lt;p&gt;Created the open-source software page with a skeleton outline and some high-level text, primarily sourced from a TransportationCamp 2018 session on the topic.&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;=== Benefits ===&lt;br /&gt;
By investing in open-source software, government agencies, companies, and non-profit organizations can leverage their investments to create shared, public benefits. In effect, those who invest in open-source software are attempting to &amp;quot;pool&amp;quot; their investments to create software that lives in the public commons. Part of organizations&amp;#039; hoped-for return on their open-source investments is that other organizations will also invest in ongoing, incremental improvements to the same software, yielding continued benefits at no additional cost. Additionally, adopting open-source software can reduce vendor lock-in to high-cost, proprietary software.&amp;lt;ref&amp;gt;[https://docs.google.com/document/d/10POhMhFW6tt1a5Sad6CWCO-VfAK8i0A1yZmg5DwGV3w/edit?usp=sharing] &amp;quot;Can Open Source Transit Software Survive?&amp;quot; TransportationCamp 2018. Discussion moderated by Sean Barbeau and Kari Watkins. Retrieved 17 January 2018&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Practices that support open-source software ===&lt;br /&gt;
Developing open-source software is a complex undertaking given the competing demands of software code that is both (a) sufficiently generalizable to be useful to a diverse array of users, and (b) sufficiently tailored to any given end-users&amp;#039; needs. It is also challenging to coordinate open-source software development, especially when there are many users likely to be impacted by any given change. Public-sector transportation agencies can advance open-source software development using the following strategies, among others: &lt;br /&gt;
* Adding open-source requirements to software procurements&lt;br /&gt;
* Adding a budget line-item and/or project task for the &amp;quot;open-sourcing&amp;quot; and related documentation of newly developed code&lt;br /&gt;
* Clearly communicate successes and open-source software implementations&lt;br /&gt;
* Coordinate with peer agencies to identify list of shared priorities and share costs for larger &amp;#039;capital&amp;#039; improvements to open-source code blocks. &lt;br /&gt;
&lt;br /&gt;
=== Transportation agencies supporting open-source software ===&lt;br /&gt;
* MTA&lt;br /&gt;
* MBTA&lt;br /&gt;
* Sound Transit&lt;br /&gt;
* Caltrans&lt;br /&gt;
* Oregon DOT&lt;br /&gt;
&lt;br /&gt;
=== Private companies developing open-source transportation software ===&lt;br /&gt;
* Cambridge Systematics&lt;br /&gt;
* Conveyal&lt;br /&gt;
* IBI Group&lt;br /&gt;
&lt;br /&gt;
=== Non-profit organizations developing open-source transportation software ===&lt;br /&gt;
* Zephyr Foundation&lt;br /&gt;
