Travel time to a destination is a key piece
of information that motorists want and need,
and is vital for good decision-making by travelers.
Technology now makes it feasible to provide
drivers with real-time information about how
long it takes to reach a given destination.
The collection of travel time data is a challenging
problem that deserves a systematic review. The
purpose of this project was to identify, review,
and synthesize information on current and potential
future efforts in real-time travel time on rural
highways. The current report focuses on rural
highway travel time data technology considerations
and is not a primer for general travel time
best practices. Also, a companion report on
arterial travel time data collection technology
can be found in Singer, Robinson, Krueger, Atkinson,
& Myers (2013). The core of the report discusses
available and emerging rural travel time (RTT)
data sources as well as implementation considerations,
advantages, and limitations of each. These technologies
researched include Bluetooth detectors, toll
tag readers, in-pavement magnetic detectors,
automatic license plate readers (ALPR), machine
vision, connected vehicle, radar/microwave/LIDAR,
inductive loops, crowdsourcing, and cell phone
signal monitoring. Several implementations of
RTT data collection are also discussed. In addition,
two case studies are reviewed in detail (in
Minnesota and Maine). The report then emphasizes
key lessons learned based on questions for a
practitioner to consider at each step of the
planning, implementation, and management process.
Although RTT data collection is a relatively
new and rapidly evolving area, RTT can be successfully
implemented when a project is properly planned
and executed. Successful implementers have carefully
considered project objectives and have provided
detailed implementation plans. Regardless of
the latest specific data collection technology,
asking the right questions is paramount, beginning
with planning, continuing to selection, and
culminating with execution and evaluation. Practitioners
who focus on asking the right questions and
heed lessons learned by colleagues will greatly
increase the chances of a successful implementation.
