Monitoring
reporting on the status
of the road network and incident
With the PIPS Travel Time Measurement System (TIMS), safety and traffic
professionals can monitor network capacity and performance as well as traffic
movements along sedions of highway or through road construdion zones.
TIMS is an Automatic License Plate Recognition (ALPR) system that analyzes traffic
patterns in real time. The system records the date, time and the license plate of
a passing vehicle between two or more points. When a vehicle passes the first
camera, a picture of the license plate is taken and Optical Character Recognition
(OCR) is performed. An encrypted version of the license plate number is stored in a
central server database along with a date/time stamp. Once the vehicle passes the
second camera, the license plate number is captured and transferred to the central
server to be matched to the initial image. A statistical analysis of each plate match is
used to determine the current average travel time of each road segment monitored.
This information can be used to determine average speeds, calculate travel times,
detect incidents and more.
The TIMS system consists
of a network of PIPS Spike+
or SpikeHD integrated
ALPR camera and processor
systems which capture plates
and process information at
each node for input into the
PIPS TIMS engine, which
incorporates over 10
years of- 9660
development effort.

and Performance
In this application, the
system is used to develop an
understanding of road network
capacity and ,performance
Traffic management personnel
can utilize road segment travel
time data to make determinations
regarding road capacity
