Maintaining the System
• Bridge, current conditions assessment– 2012 National Bridge
Inventory (NBI) Database
– Structural deficiency status based on bridge condition
– Functional obsolete status based on geometrics, e.g., number and width of lanes
– All bridges in region greater than 20-foot length
13
Summary Bridge Conditions in Chattanooga Region
Maintaining the System (continued)
15
• Pavement, current conditions assessment– 2008 Highway
Performance Monitoring System (HPMS) database
– Percent of lanes miles in good/fair/poor condition based on roughness
– Thresholds defined by Federal Highway Administration
– Sample data
Summary Pavement Conditions in Chattanooga Region
Reducing Congestion
• Base-year congestion analysis– Worst congestion along
I-24 and I-75– Severe congestion at
junction of I-24/I-75– U.S. 27 north of river– Hamilton Place Mall – Northgate Mall
• Downtown relatively uncongested
16
Reducing Congestion (continued)
• Future-year congestion analysis– U.S. 27 congestion relieved
(widening project underway)
• Outward expansion and general increase in severity of general congestion due to population and employment growthover time
17
Reducing Congestion (continued)
• Mobility corridor analysis– More detailed assessment
of 13 mobility corridors– Geographic sample of
corridors with high volume auto and truck traffic (“scale 3”)
– Corridors evaluatedand scored• Congestion Management
Process (CMP) route• 2040 congestion levels• Key freight route• Supports high-volume
external to external (through) trip movement
18
Improving Safety
• Systemwide safety analysis– Traffic crashes leading cause
of death 5-34 years old– 55 deaths; 330 injuries
annually in region– $1,700 per person
• RTP Emphasis areas– Roadway departure– Aggressive driving– Intersection crashes
19
Improving Security
• Climate adaptation analysis– Critical transportation
assets defined• Chickamauga Lock and Dam• Chattanooga Airport
and SR 153 access• Interchange of I-75/I-24• Enterprise South road
and rail access• Downtown bridges• Sequoyah nuclear plant
– Redundant facilities and evacuation routes identified
20
Providing Access
• Accessibility analysis to measure proximity of people and homes to– Active transportation
facilities• Bicycle facilities (B-LOS of B or
better)• Parks and Open Space • Trails• CARTA Transit Stops
– Health-related destinations• Healthcare Facilities• Grocery Stores and
Supermarkets• Farmers Markets /Community
Gardens/ Mobile Markets• Public and Private Schools
21
Environmental Sustainability Needs
1/4 Mile Walk Access 1 Mile Bicycle Access
Providing Access (continued)
22
Connecting the System
• Transit Gap Analysis– Locations of highest transit
demand• Population and household density• Land use mix• Intersection density• Distance to nearest transit stop• Jobs within one mile
– Mapped against existing and planned infrastructure
– Low income, minority and elderly population as overlay
23
Connecting the System (continued)
• Bicycle Gap Analysis– Locations of highest bike
demand• Population and household density• Intersection density• Jobs within one mile• Distance to nearest transit stop• Distance to commercial store• Public/private schools within one
mile• Parks and recreation facilities
within one mile
– Mapped against existing and planned infrastructure
– Low income, minority and elderly population as overlay
24
Connecting the System (continued)
• Pedestrian Gap Analysis– Locations of highest pedestrian
demand• Population and household density• Intersection density• Jobs within one mile• Distance to nearest transit stop• Distance to commercial store• Public/private schools within one
mile• Parks and recreation facilities
within one mile
– Mapped against existing and planned infrastructure
– Low income, minority and elderly population as overlay
25
Improving Livability and the Environment
• Livability corridor analysis– More detailed assessment
of 24 livability corridors– Geographic sample of
corridors with potential for broad multimodal enhancements and VMT reduction (“scale 2”)
– Corridors evaluated and scored in terms of:• Potential complete streets
corridor, 2035 Plan• Lack of bike/pedestrian/
transit infrastructure• Population and employment
density• Congestion levels
Operating the System
• Operations assessment– Extensive ITS coverage on
freeways; opportunity to extend into north Georgia
– Downtown Chattanooga has extensive communication network for managing key arterials in real time; opportunity to extend to more corridors with centralized management center
– Opportunity for transit signal priority for key corridors
27
