Thanks for writing. You will need to chose a category for your submission:
(ii) Categories: Applications may include features and functionality that provide solutions for drivers, solutions for pedestrian and cyclists, or both. At the time of submission, Makers will be required to select one of two categories, solutions for drivers, or solutions for pedestrians & cyclists (the “Categories”), which best describes the intended end user and primary features and functionality of the Application. At any time, and at its sole discretion, the Sponsor will have the ability to re-assign a submitted Submission from one Category to another. Submissions in each Category are eligible for different prizes though both Categories and will be eligible to win the Honorable Mention and Best Solutions for Multi-Modal Connections prizes identified in Section 7.
You are only able to submit multiple applications if they are substantially different: (vii) Multiple Submissions: A Maker may submit more than one Submission, however, each Submission must be unique, as determined by the Poster and/or the Administrator.
