Mobility analysis is used
to identify trends and examine issues related to urban
traffic congestion. Mobility analysis can be used to:
Help evaluate and prioritize project
needs in terms of the efficiency of traffic flow
for development of the Six Year Highway Plan;
To compare cities or corridor’s
congestion levels; and
To be used to set benchmarking
goals for future congestion/mobility levels for
roadway corridors and cities.
Mobility
Analysis Team
The mobility team is comprised of members
of representatives from Divisions of Planning, Traffic
Operations and the Federal Highway Administration. Agendas
from team meetings can be found in the mobility analysis
links. The purpose of this team is to develop, test
and evaluate mobility analysis performance measures
for Kentucky.
Mobility
Analysis Tools
Historically, the Highway Capacity Manual
and the Highway Capacity Software have been the tools
used to evaluate traffic flow. New tools have emerged
in recent years including:
Travel time based measure such as
the Travel Time Index (TTI), the Travel Rate Index
(TRI), and the buffer index. These new travel time
base measures were developed by the Texas Transportation
Institute through the Annual Urban Mobility Study;
Multimodal Level of Service analysis.
This adaptation of the Highway Capacity Manual expands
capacity analysis to other modes of travel such as
transit, pedestrians and bicycles;
Use of ITS Archived Data for various
mobility efforts such as speed, volume and vehicle
classification data.
Traffic Simulation models such as
FHWA’s CORSIM model.
