Complete Streets

Complete Streets in Atlanta are designed to provide safe access for all users, such as pedestrians, bicyclists, motorists, and transit riders of all ages and abilities. These streets vary in design based on location and use, and may include sidewalks, bike lanes, and transit facilities (ATLDOT). By accommodating diverse modes of transportation, Complete Streets aim to create a more balanced and efficient traffic flow.

North Avenue Smart Corridor

The North Avenue Smart Corridor is a significant project under Atlanta’s Renew Atlanta initiative. This corridor has been transformed into a “living lab” to test technology-driven solutions for safe, efficient, and environmentally friendly mobility (Arcadis).

Intelligent Transportation Systems (ITS)

The implementation of Intelligent Transportation Systems (ITS) along North Avenue uses advanced sensing technologies to manage traffic flow, monitor statistics such as speed and volume, and adapt traffic patterns to improve transit efficiency and safety (Arcadis).

The implementation of these projects and trends reflects Atlanta’s commitment to improving traffic flow, enhancing safety, and creating a more efficient transportation ecosystem. For commuters, staying informed about these developments can lead to better navigation strategies and less time spent in gridlock.

Navigational Tips

Navigating Atlanta’s busy streets and highways can be challenging, especially during peak traffic hours. Below are some navigational tips that can help commuters, new residents, frequent travelers, delivery drivers, tourists, and local businesses make the most out of their time on the road.

Alternative Routes

Finding alternative routes can significantly reduce commute time and help avoid congested or accident-prone areas. Here are a few suggested routes:

1. Surface Streets: Using surface streets instead of highways can often save time. Roads such as Piedmont Avenue and Moreland Avenue can be useful alternatives to major highways like I-85.

2. Back Roads: Streets like Norcross-Tucker Road and Roswell Road can serve as alternative arteries to avoid heavy traffic on major routes.

3. Perimeter Route: For those commuting to the suburbs, using the I-285 Perimeter can sometimes be faster than cutting through the city.

Traffic Hotspots to Avoid

Certain stretches of road are consistently congested and should be avoided whenever possible. The Atlanta Regional Commission gathered data on the most problematic areas (AJC). Here are a few traffic hotspots:

1. I-85/I-75 Split: This section is notorious for long bottlenecks, with an average duration of over 4 hours. Avoid this area during peak hours whenever possible.

2. I-75 North at Chastain Road/Exit 271: Known for being a particularly bad stretch, it records an average duration of over 2.5 hours.

3. Downtown Connector and I-20 at I-85/I-75 South: Another major trouble spot with average congestion durations exceeding 4 hours. It’s best to plan alternate routes around this area.

By avoiding these hotspots and exploring alternative routes, you can increase your efficiency on the road and minimize the stress of navigating Atlanta’s traffic.

Innovative Solutions

Intelligent Transportation Systems

Atlanta has adopted Intelligent Transportation Systems (ITS) to enhance its traffic flow. One prominent example is the North Avenue Smart Corridor, transformed into a “living lab” as part of Atlanta’s Renew Atlanta initiative. The corridor utilizes sensing technologies to manage real-time traffic data, such as speed, volume, and vehicle types.

Key features of ITS on North Avenue include:

• Real-Time Traffic Monitoring: Sensors and cameras collect data to monitor and manage traffic conditions.
• Adaptive Traffic Signals: Traffic lights adjust dynamically based on real-time traffic flow, reducing congestion.
• Priority for Emergency Vehicles: The system prioritizes the movement of ambulances and fire trucks during emergencies.
• Environmental Benefits: Studies show the system reduces energy consumption, making transportation more eco-friendly.

Impact of ITS Implementation

The implementation of ITS along the North Avenue corridor has shown significant positive effects on traffic efficiency and safety.

Figures from (Arcadis)

• Accident Reduction: ITS has led to a 20-35% decrease in accidents along North Avenue, improving overall safety.
• Enhanced Traffic Flow: The adaptive traffic signals have improved average traffic speed by about 15%.
• Emergency Handling: The system prioritizes emergency vehicles, ensuring quicker response times and safety.
• Environmental Sustainability: The ITS implementation has reduced energy consumption, contributing to environmental sustainability.

The ITS along the North Avenue corridor is monitored from a digital mobility center staffed with experts from the Georgia Institute of Technology and the Georgia Department of Transportation, ensuring that the system continually adapts and improves. This collaborative approach helps maintain optimal traffic flow and safety, making it a model for other areas in Atlanta.

Safety Precautions

Ensuring safety while navigating Atlanta’s roads is crucial, especially given the city’s notorious traffic. Here, we discuss hazardous highway stretches and effective defensive driving techniques to help you stay safe.

Hazardous Highway Stretches

Certain stretches of highway in Atlanta pose significant risks due to high traffic volumes and frequent accidents. Here are some of the most perilous sections:
