Ferry Travel Times
Bluetooth Readers used to estimate wait times
Anonymous Wireless Address Matching using Bluetooth enabled
devices
Tested multiple locations to determine which would provide the
most matches for estimates

Current Improvement Activities
Full Matrix, Color DMS Signs for Ferry Landings
– FY 2016 Letting
Bolivar CCTV poles and new Wireless Backhaul
– Currently being procured and installed
Automated Identification System to Improve Travel Time Accuracy
– Recently installed and began data collection
Marine Automatic Identification System (AIS)
AIS is an automatic tracking system used on ships
Key information transmitted includes:
– Unique ship ID
– Position
– Course/heading
– Speed
International organizations and the US Coast Guard require AIS transmitters on ships of 300 tons or more and all passenger ships regardless of size.
Applications and Benefits:
– Collision avoidance
– Vessel traffic services
– Maritime security
– Search and rescue
– Accident investigation
– Fleet and cargo tracking

AIS at the Galveston-Bolivar Ferry
This is a fairly simple system:
– AIS receiver (reads VHF transmissions & GPS signals)
– AIS antenna & cabling
– Lightning/surge protection
– Internet connection (currently cellular; transition to TranStar net later)
– Back end processing, interface and data archive
Collaboration between TTI and TxDOT Houston District
Installed late September 2015 at the Galveston Ferry Office & initial data
processing began on October 5
– Hundreds of thousands of data points are being generated per day
16
AIS Coverage
Most position data is within 20 miles, but reading up to 100 miles away
Typically we are covering about 1500 square miles, easily getting ferry trips
17
AIS Interface
Example of visual interface
18
Ferry Traveler Information
Travel time generated by Wi-Fi probes, CCTV images
New information is anticipated to include:
– Number of ferries in operation
– Departure times
– Estimated arrival times
– Real-time map
Security: AIS data is public info = kill-switch capability
