Success Story: City of Manchester, NH

Cyvl partnered with civil engineering firm Kimley-Horn to execute a comprehensive pavement condition assessment across 412.5 miles of roadways in Manchester, the largest city in New Hampshire.

This project was designed to harness Cyvl’s latest sensor technology and data analysis methodologies. By providing detailed pavement condition scores and a robust inventory of urban assets, Kimley-Horn aimed to improve transportation infrastructure maintenance decision-making and establish a new standard in urban infrastructure management for the City of Manchester, NH.

Challenge

The large size of Manchester’s road network posed a substantial challenge regarding data collection and analysis. The city required a cost-effective, detailed pavement condition assessment to inform maintenance decisions effectively. Additionally, a comprehensive inventory and geolocation of various urban assets were needed.

Solution

Cyvl and Kimley-Horn deployed 3 advanced sensors capable of capturing 2D and 360-degree imagery to address these challenges. This technology facilitated a thorough evaluation of pavement conditions and enabled the cataloging of essential right-of-way assets. The Cyvl platform also integrated street view imagery, offering an interactive interface for easy navigation and detailed data visualization.

Implementation

The implementation phase involved mounting Cyvl’s LiDAR and high-resolution imagery sensors on 3 vehicles that simultaneously drove around Manchester’s roadways for 3 days, covering 412.5 miles.

This method ensured the collection of high-quality data across the city, allowing for an in-depth analysis of pavement conditions and asset inventory.

Results

1. Detailed Pavement Scoring:

• The pavement was assessed on a scale of 1 to 100, with 1,416,026 individual distress details identified, providing a comprehensive understanding of the pavement condition across Manchester.

2. Extensive Asset Cataloging and Geolocation:

• A total of 12,249 streetlights, 9,547 trees, 9,624 manhole covers, 9,268 catch basins, and 33,255 MUTCD signs were meticulously cataloged and geolocated, enriching the city’s asset management database.

3. Enhanced Data Visualization and Access:

• The integration of street view imagery into the Cyvl platform allowed city planners and engineers to explore and analyze the roadway data interactively, enhancing the usability and application of the information gathered.
