The Importance of Accurate Road Width and Lane Measurements in Smart City Projects

Learn how precise road width and lane measurements power smart city planning, traffic safety, ADA compliance, and funding with Urban SDK’s geospatial AI.

At Urban SDK, we believe that building smarter, safer, and more efficient cities starts with data—and not just any data, but precise, actionable insights.

In a world where infrastructure is expected to be connected, responsive, and equitable, road with and lane measurements shape everything from traffic flow and pedestrian safety to emergency response and infrastructure funding. And that’s exactly why we’ve made it our mission to help cities get it right.

Why Road Width and Lane Data Matter More Than Ever

When we talk about road width and lane configuration, we’re talking about more than lines on pavement. We're talking about critical factors that influence every smart city initiative, including:

• Traffic modeling and flow efficiency - Narrow roads create bottlenecks. Excessively wide lanes can encourage speeding. Accurate width data enables cities to simulate real-world traffic scenarios, plan better detours, and reduce congestion
• Safety improvements and Vision Zero- Misjudged lane widths are directly linked to crash rates. A reduction in lane width by even one foot can lower vehicle speeds and improve pedestrian safety. Our clients use precise data to identify dangerous corridors and reengineer them for safety
• Multimodal planning - Cities are under pressure to accommodate not just cars, but also buses, bikes, scooters, and pedestrians. You can’t plan bike lanes or curbside drop-offs unless you know how much space you actually have to work with
• ADA and accessibility compliance - To meet federal requirements, cities must design sidewalks, curb ramps, and pedestrian spaces within defined spatial standards. These depend entirely on having accurate curb-to-curb and lane-to-lane measurements
• Infrastructure funding and compliance - Federal and state grants often require exact roadway geometry to support transportation proposals. Without solid data, cities may leave money on the table or risk non-compliance

The Problem with Traditional Measurement Methods

Historically, cities have measured road widths using survey crews, paper maps, or legacy GIS files. The problems? They’re:

• Time-consuming: Sending out crews to measure miles of roadway manually is inefficient and costly.
• Infrequently updated: Traditional surveys might only be done once every 5–10 years, leaving cities with outdated data.
• Incomplete or inconsistent: Older GIS files often have missing attributes, mismatched lane counts, or inaccurate widths—especially in fast-growing areas.

In an era where transportation infrastructure evolves rapidly and public expectations are higher than ever, we need a better way.

Our Solution: Geospatial AI That Measures with Precision

At Urban SDK, we’ve developed a smarter, scalable way to inventory roadway dimensions using high-resolution satellite imagery and artificial intelligence. Our Roadway Characteristics Data product is designed specifically to help public leaders:

• Extract lane counts and lane widths automatically
• Measure curb-to-curb road widths at scale
• Differentiate between road types, from local streets to arterials
• Classify additional features like medians, bike lanes, and parking strips

Our AI models analyze aerial imagery and generate GIS-ready outputs—so you get clean, accurate road data that plugs directly into your existing transportation systems.

Key Features of Our Platform:

• Citywide coverage: We analyze the entire network, not just sample corridors.
• Repeatable and current: Need to remeasure after a road expansion? We can update data in days, not months.
• Seamless GIS integration: Use our data within your mapping, modeling, or asset management tools.
• Scalable to any city size: Whether you manage 100 miles or 10,000, our platform adapts.

Use Cases in Action

Here’s how cities are using our road width and lane data right now:

• Reconfiguring overly wide arterials into safer complete streets with narrower lanes and added bike infrastructure.
• Supporting grant applications that require clear documentation of road conditions and design.
• Optimizing signal timing and lane striping plans based on actual curb-to-curb dimensions.
• Prioritizing repaving projects based on road geometry and usage data.

Why It Matters for Smart Cities

Smart cities thrive on real-time, high-resolution, and actionable data. When you’re implementing connected vehicles, adaptive traffic signals, or curb management platforms, every inch counts. You can’t rely on out-of-date or estimated dimensions when you're building dynamic infrastructure systems that need to respond intelligently.

By providing exact lane widths and road geometries, we help cities:

• Reduce traffic-related injuries
• Optimize land use
• Prepare for autonomous and connected vehicles
• Improve quality of life for residents

Let’s Build Smarter, Together

If your city is still relying on outdated maps or incomplete datasets, it’s time for an upgrade. Our platform makes it easy to collect, manage, and apply precise roadway measurements for better planning and decision-making.

With Urban SDK, you’re not just collecting data—you’re building a smarter foundation for your city's future.
