DDOT SUMMER 2014

  1. 1. 1 Research Program Highlights District Department of Transportation Summer Research Interns! Summer/Fall 2014 DDOT welcomed nine interns this summer, ranging from college stu- dents to PhD candidates. The interns worked on various research projects across the agency and presented them on August 7th. Tamiko Toye and Gervais Mbunkeu worked with Cesar Barreto in IPMA doing work on ADA data collection and software evaluation. Zuxuan Deng did research on the Truck Trip-Generation element of the DDOT freight model, working under Eulois Cleckly in PPSA. Yanan Xin worked in QA/QC with James Graham, Amanda Harvey, and Jose Colon, improving DDOT’s asset inventory data management. Amy Liang did Red-Top meter implementation work with TOA and Evian Patterson. Pranay Bagde and Akhil Jain worked with IPMA and Ali Shakeri on agency coordination proce- dures with large-scale development. Joseph Vincent and Anita Kinney worked on the archival and digitization project in the library. From left to right: Zuxuan Deng, Yanan Xin, Tamiko Toye, Amy Liang, Joseph Vincent, Gervais Mbunkeu FY 2015 Research Projects Projects for the upcoming fiscal year have been selected. The Research Advisory Committee (made up of the Associate Directors from each administration) met on July 17th to select the FY15 research projects. Projects will be funded as funding becomes available to research, starting at the top of the list. Rank Project Name 1 Performance Metrics and Supportive Analysis Methodologies for Highly Urbanized, Multi-Modal Systems 1 Analysis of Per-Ride Fare Data for Capital Bikeshare 3 Relating Capital Bikeshare Usage to Existing and Future Bicycle Count Data 4 Integration of Renewable or Cleaner Energy Generation Technology into Transportation Infrastructure 5 Traffic Signals and ITS Communication Security Audit 6 DDOT Cost Estimating for Professional Engineering Services 7 Compliance, Perception and Effectiveness of Rectangular Rapid Flashing Beacons (RRFB) and Pedestrian Hybrid Beacons (HAWK Signals) in the District of Columbia
  2. 2. 2 Sharing DC History DDOT Data Initiative The DDOT Library & Archives has joined the wide world of social media! The DDOT tumblr launched in June to much interest. Photos posted on the page have been featured in Greater Greater Washington, Old Time DC, and the Washington Post Express. The DDOT Library & Archives contain photos, maps, and documents from across the years, documenting the growth and changes in DC through history and transit. The goal of the tumblr is to share these pieces of history with a wider audience. The DDOT tumblr has connected with other major libraries and archives in the area, such as the DC Public Library System, the Smithsonian, and the National Archives. In conjunction with Chris Quay and the Communications department, we hope to share more in the upcoming weeks! Research and OITI are leading an effort to streamline data management at DDOT. The goals of the effort are to: a. get a better handle on data that is already available at DDOT, b. create a framework and business process that enables us to store that data in a consistent, query-able format, c. integrate disparate data platforms where practical, and d. provide access to various data users at DDOT. To get started, Research and OITI are compiling an inventory of existing data at DDOT through a wiki: https://sp3.ddot.dc.gov/ oi/data/DataWiki/Home.aspx Moving forward, the data team will be working to create a common interface, where appropriate, to streamline access to various datasets at the agency. This will include data stored at DDOT’s Transportation Safety Data Center at Howard University. Training will be made available on accessing the data stored at the Data Center. The team will also be providing contracting language on standard data formats to include in contracts where data will be collected. This will enable future data collection to be easily integrated across the agency. Lastly, the team is looking at moving extant data to a common warehouse where feasible, which will also streamline access. If you have datasets, please add information on them to the data wiki! If you have questions, please contact James Graham, Stephanie Dock, or Soumya Dey. Streetcar tracks at M and 30th Street NW in Georgetown, December 8th, 1959. http:ddotdc.tumblr.com
  3. 3. 3 Project UpdatesIntern Spotlight Amy Liang, our research intern with the TOA parking team since this summer, is a graduate student from the Catholic University of America. She is pursuing her PhD degree in Civil Engineering. Amy works with the Red Top Meter program and her work to date includes developing a metric on meter inspections and conducting an occupancy study. As the inspection process of the Red Top Meters goes, she keeps updating the inspection database and collaborating with OITI team on updating parking meter GIS information. Starting this fall she is also helping with the Residential Permit Parking (RPP) program. Her goal is to develop an operational method which can facilitate the RPP decision making process. If successful, her work would effectively save process time later and make our policy more operable both qualitatively and quantitatively. The Research Program recently gave a presentation at the DDOT FY15 Paving Plan Development Workshop on the results of a survey of how peer cities develop their paving plans. The survey found that in most cases the selection of streets is a mix of quantitative and qualitative factors, with varying public and political input. Common factors included pavement condition, geographic equity, and demands on the street (including citizen complaints). Research can do a scan like this for your next project!
