Archived Data User Service (ADUS)
refers to traffic and accident data collected by TMCs that is archived
for real time traffic management, planning, developing new traffic
management strategies, or research.
Key Results
ADUS is not common. Many state
DOTs and TMCs are still developing their ADUS systems, while others
are not yet considering archiving their data.
Portland, Oregon TransPort
- The TransPort
(Transportation Portland) program conducted an experiment in which
10 mainline inductive loop detector stations (with detectors located
in each lane) and associated on-ramp detectors at 10 eastbound
on-ramps were installed along an 11-mile corridor along eastbound
US 26 between Helvetia Road and Skyline Road in Portland, Oregon.
- Vehicle counts, occupancy and speeds were collected at-20 second
intervals and then archived.
- The archived data will assist in determining the best performance
measures for obtaining simple, quick and accurate ideas about
the functionality of the corridor, enhancing decision-making.
- It was determined that such simple, directly measurable variables
would be useful in setting standards and determining widely-applicable
performance measures.
Benefits
- Huge reductions in costs and
space needed to store and access data, as compared to traditional
data collection.
- Encourages the use of data
for multiple purposes.
- Promotes integration of ITS with traditional information systems.
- Allows for better long-term
transportation management and planning.
- The detailed nature of ITS-generated
data allows for more accurate analysis and makes possible those
applications that were previously too costly to undertake.
Implementation Challenges
- The reluctance to share data among
jurisdictions will continue to hinder full ADUS implementation.
- The lack of ADUS standardization for both data
quality and accessibility slows the integration of different information
from multiple sources.
- Organizations like the TMC generally do not have
the staff needed for both incident management and data archiving.
