Ever wonder whether you should be using JSON or XML when talking to a server from your mobile app? This paper, presented at the 2104 Transportation Research Board meeting, answers this question by benchmarking against MTA NYC’s SIRI API (hint – its not XML!). Read the full paper for details on the benchmark results, as well as other optimizations you can use to make your app snappy and responsive, and reduce the user’s waiting time for new real-time info.

In a December 20, 2012 USDOT press release, the Travel Assistance Device (TAD) was highlighted as an example of a high-value product created with University Transportation Center (UTC) funding.
The Travel Assistance Device (TAD) was featured in the Summer/Fall 2012 issue of Ignition Magazine, published by the Transportation Research Board Innovations Deserving Exploratory Analysis program.
Today, researchers at the Center for Urban Transportation Research and the Computer Science and Engineering Department at the University of South Florida were awarded U.S. Patent # 8249807 – Method for Determining Critical Points in Location Data Generated by Location-Based Applications.
A critical point method is used to determine the points of a real-time stream of location data, such as Global Positioning System (GPS) data, that should be retained based on their importance in reconstructing the travel path of a mobile device. The method may run on a mobile device or on a server. When run on a mobile device, the method reduces the amount of data transferred between mediums by only transferring points that are critical to reconstructing the path of travel of the mobile device. This reduction saves power used in the wireless transmission and reception of the non-critical data and the bandwidth used while transmitting non-critical data. The method may be run every time a new position is calculated. When a new position is determined to be a critical point, the point is transmitted. If the new position is not a critical point, then the point is discarded. More at http://www.freepatentsonline.com/8249807.pdf
