Maryland Statewide Congestion Assessment
Location: Statewide, Maryland
Client: Maryland State Highway Administration
At the request of Maryland State Highway Administration (MSHA),
JMT performed a statewide congestion assessment to better
systematically evaluate congestion in different parts of the
state.
The project involved gathering traffic
data, using the roadway inventory data and gathering additional
information such as passing zones on two lane roadways. A committee
was established to evaluate different methods for analyzing the
roadways. Based on the recommendations, various methods were used
such as Highway Capacity Manual analysis, SYNCHRO analysis and
aerial surveillance.
The results were then depicted on the
statewide GIS based mapping to automate the creation of linearly
referenced line events representing peak morning and evening Levels
of Service of traffic by drive direction along all state-maintained
roads throughout Maryland. Also, JMT designed and generated
Congestion Maps displaying Level of Service by Route for 23
Maryland counties. GIS and Map deliverables were then
compiled and submitted together with summary of analysis methods
employed. The results were placed on the MSHA internal website.
The JMT Statewide Congestion Assessment was a success in
accomplishing the MSHA's objective to better systematically
evaluate congestion in different parts of the state.
