    • Abstract:
      The main objective of this project is to develop and conduct limited testing of novel sensors using Bluetooth technology

      (BT) to estimate OD demands and station wait times for users of public transit stations. The NYU research team tested the

      feasibility of the utilization of sensors with Bluetooth technology to estimate Origin-Destination (OD) demands and station waittimes

      of users of transit systems with a focus on subway systems. For example, if the entrance and exit turnstiles at subway stations

      were equipped with this type of sensors, it is possible to capture OD information for some of the riders with activated devices.

      Estimation of daily and hourly Origin-Destination (OD) demands and delays is important for transit agencies because it

      can help improve their operations, reduce delays, and mitigate cost, among other benefits. The proposed method of tracking

      Bluetooth IDs uses inexpensive, small, and easy to deploy wireless detectors / readers with specialized software developed by the

      research team. This is a low-cost and viable alternative to traditionally used surveys or other advanced technologies.

      Following a literature review and device testing, a series of one-day pilot tests are conducted in coordination with the

      MTA to iron out all of the possible hardware and software issues. Following further consultation with the MTA, a full one day to

      one week indoor tests are conducted with continuous data collection and monitoring to assess the feasibility and usefulness of longterm

      data collection using the proposed sensor technology. Two software tools to post process the collected data and to perform

      self-diagnosis and remote data acquisition functions are developed as part of the overall research project. The results and

      recommendations are provided to the MTA and other interested transit agencies.
