Learn about Roadway Design Principles from Chastain-Skillman, who has completed roadway design projects in the surrounding areas of Orlando, FL and Nashville, TN.

In today’s rapidly developing world, the importance of efficient and safe roadways cannot be overstated. With the continued rise in vehicles and urbanization, roadway design has become paramount in ensuring that our roads can effectively handle traffic while maintaining safety and delivering an optimal user experience.Β 

Let’s delve into the primary principles of roadway design – safety, efficiency, and user experience.

Roadway Design for Safety

Safety is the cornerstone of any roadway design. An unsafe road not only risks lives but also causes economic loss due to accidents and traffic congestion. Here are some crucial factors that traffic engineers consider for safe road design:

  • Geometric Design: This encompasses the layout, alignment, and width of lanes. It ensures that roads curve and incline in ways that are predictable and manageable for drivers.
  • Traffic Control Measures: These include signals, signage, and road markings that guide and regulate traffic, making sure drivers are well-informed and forewarned of conditions ahead.
  • Pedestrian and Cyclist Facilities: Dedicated lanes and crossings for pedestrians and cyclists reduce the risk of accidents by segregating vehicular traffic from non-motorized users.
  • Barrier Systems: Proper barriers like guardrails, medians, and crash cushions help prevent vehicles from veering off the road or into oncoming traffic.

See a completed project from Chastain-Skillman for Bike Lanes and Enchanced Drainage that improved roadway safety for cyclists biking to Lake Hollingsworth. 

Roadway Design for Efficiency

Efficiency in roadway design ensures that roads cater to the volume and type of traffic, minimize congestion, and provide seamless transit for users. Important factors to consider include:

  • Capacity Planning: By assessing current and future traffic volumes, designers can allocate appropriate lane widths and numbers to prevent bottlenecks.
  • Intelligent Transport Systems (ITS): Leveraging technology such as sensors and cameras can help in real-time traffic monitoring and management.
  • Intersections and Traffic Flow: Properly designed intersections with overpasses, underpasses, or roundabouts can enhance traffic flow, reducing stop-and-go scenarios.
  • Maintenance and Durability: Durable road materials and regular maintenance reduce the need for constant repairs, ensuring roads remain usable and efficient.

Roadway Design for User Experience

Highway design goes beyond the mere creation of lanes and traffic signals. It focuses on the entire journey of a driver. Everything from the layout, visible features on the road, gradients, intersections, to sight distances matters. Roadway and traffic engineers bear a significant responsibility in ensuring roads are designed to the highest standards, offering not just safety but also a pleasant driving experience. 

With well-planned aesthetics, landscaping, and infrastructural facilities such as rest stops and view points, the entire driving journey can become an experience in itself.

See a completed project from Chastain-Skillman for a complex redesign of Sebring Parkway. We succeeded in widening the two-lane road to a five-lane road while improving lighting and signalization.
