AM Peak Morning South Bound How to Read these Congestion Charts Each chart shows changing traffic conditions for different times of day by location along the I-30 freeway corridor. The horizontal axis (x-axis) represents time of day, while the vertical axis (or y-axis) depicts different segments from north (top - Hwy 67/ McCain) to south (bottom - I-30/65th Street). Each chart just shows one direction of travel (southbound or northbound). Each shows a single scenario (build alternative and year), such as “southbound AM, 6+CD lane split diamond, in 2041.” The best way to read them is to proceed from left to right, by time of day. Thus, you can start at the earliest interval on the far left of each chart. This is typically 5:45 AM for the morning charts, and 3:45 PM for the afternoon charts. DRAFT Speed (MPH) For example, for southbound morning traffic, tracing a line from top to bottom you get a snapshot of traffic conditions along the corridor at a single moment in the morning rush hour. Since southbound traffic travels from the top of the chart to the bottom, you can see where congestion starts and where it stops at that single time in the morning rush. Moving the line rightward advances you to the next moment in time, and then the next, and so on. By moving left to right you can see how congestion worsens, improves or stays the same at different points and times along the corridor. The same can be done with the northbound traffic charts except the traffic is traveling from the bottom of the chart to the top. 60–70 50–60 40–50 30–40 20–30 10–20 0–10 AHTD Note: All models including the Exisng and Future No-Acon models were originally analyzed for a 2-hour peak period in the I-30 PEL.

AM Peak Morning South Bound How to Read these Congestion Charts
Each chart shows changing traffic conditions for different times
of day by location along the I-30 freeway corridor. The horizontal
axis (x-axis) represents time of day, while the vertical axis (or
y-axis) depicts different segments from north (top - Hwy 67/
McCain) to south (bottom - I-30/65th Street). Each chart just
shows one direction of travel (southbound or northbound).
Each shows a single scenario (build alternative and year), such as
“southbound AM, 6+CD lane split diamond, in 2041.”
The best way to read them is to proceed from left to right, by
time of day. Thus, you can start at the earliest interval on the far
left of each chart. This is typically 5:45 AM for the morning charts,
and 3:45 PM for the afternoon charts.
DRAFT
Speed (MPH)
For example, for southbound morning traffic, tracing a line
from top to bottom you get a snapshot of traffic conditions
along the corridor at a single moment in the morning rush hour.
Since southbound traffic travels from the top of the chart to the
bottom, you can see where congestion starts and where it stops
at that single time in the morning rush. Moving the line rightward
advances you to the next moment in time, and then the next,
and so on. By moving left to right you can see how congestion
worsens, improves or stays the same at different points and times
along the corridor.
The same can be done with the northbound traffic charts except
the traffic is traveling from the bottom of the chart to the top.

PM Peak Afternoon South Bound How to Read these Congestion Charts
Each chart shows changing traffic conditions for different times
of day by location along the I-30 freeway corridor. The horizontal
axis (x-axis) represents time of day, while the vertical axis (or
y-axis) depicts different segments from north (top - Hwy 67/
McCain) to south (bottom - I-30/65th Street). Each chart just
shows one direction of travel (southbound or northbound).
Each shows a single scenario (build alternative and year), such as
“southbound AM, 6+CD lane split diamond, in 2041.”
The best way to read them is to proceed from left to right, by
time of day. Thus, you can start at the earliest interval on the far
left of each chart. This is typically 5:45 AM for the morning charts,
and 3:45 PM for the afternoon charts.
DRAFT
Speed (MPH)
For example, for southbound morning traffic, tracing a line
from top to bottom you get a snapshot of traffic conditions
along the corridor at a single moment in the morning rush hour.
Since southbound traffic travels from the top of the chart to the
bottom, you can see where congestion starts and where it stops
at that single time in the morning rush. Moving the line rightward
advances you to the next moment in time, and then the next,
and so on. By moving left to right you can see how congestion
worsens, improves or stays the same at different points and times
along the corridor.
The same can be done with the northbound traffic charts except
the traffic is traveling from the bottom of the chart to the top.

PM Peak Afternoon North Bound How to Read these Congestion Charts
Each chart shows changing traffic conditions for different times
of day by location along the I-30 freeway corridor. The horizontal
axis (x-axis) represents time of day, while the vertical axis (or
y-axis) depicts different segments from north (top - Hwy 67/
McCain) to south (bottom - I-30/65th Street). Each chart just
shows one direction of travel (southbound or northbound).
Each shows a single scenario (build alternative and year), such as
“southbound AM, 6+CD lane split diamond, in 2041.”
The best way to read them is to proceed from left to right, by
time of day. Thus, you can start at the earliest interval on the far
left of each chart. This is typically 5:45 AM for the morning charts,
and 3:45 PM for the afternoon charts.
DRAFT
Speed (MPH)
For example, for southbound morning traffic, tracing a line
from top to bottom you get a snapshot of traffic conditions
along the corridor at a single moment in the morning rush hour.
Since southbound traffic travels from the top of the chart to the
bottom, you can see where congestion starts and where it stops
at that single time in the morning rush. Moving the line rightward
advances you to the next moment in time, and then the next,
and so on. By moving left to right you can see how congestion
worsens, improves or stays the same at different points and times
along the corridor.
The same can be done with the northbound traffic charts except
the traffic is traveling from the bottom of the chart to the top.
