Hi, I am Mary Bandziukas, writing from New York City. I was recently hired by the NYC Dept.of Transportation, where I am on the asset management GIS team. We perform record-keeping and research functions. We currently are refining a model to prioritize refurbishment of pavement markings. I was with this team part time for almost 2 years, during which I began to develop a pedestrian trip model for the agency. One purpose of the model will be to calculate pedestrian risk of being involved in a ped-vehicle accident. Using documented trip generation rates, I am calculating trips per lot based upon land use, and I will need to decide how to calculate modal split. The agency has short-term (2- or 3-hour) ped counts and is beginning to collect some long-term counts which may be useful in validating the model.
The main innovative GIS successes for me over the past few years have been:
- learning about and using the SatScan tool to generate center lines for sidewalk and crosswalk polygons for the purpose of developing a pedestrian network
- investigating potential applications of the agency's DEMs generated from aerial LiDAR. We were interested in the potential to identify road imperfections such as potholes. I implemented ESRI's Bluespots model in this work. We will have access to mobil LiDAR in the future, which will likely give much better results.
- automating mapping of work orders and other documents with a Python program
If I have to identify areas of expertise, I would say I have had an eclectic career so far, with experience in urban planning and higher ed, as well as recently-developed skills in research and with respect specifically to GIS, in map design and cartography. Long-term, my "dream" would be to implement service-learning projects between students and community groups. Shorter-term, I want to provide GIS services to community groups on a volunteer basis. I expect to learn a great deal about community need and technical aspects of GIS in this way.
Thank you for implementing this group. I am looking forward to seeing all the interesting things people are doing around the world.
