Pavement Evaluation and Complete Asset Inventory for the City of Bowie, Maryland
Scope: Transconomy executed a project for the City of Bowie to deliver a roadway asset inventory and pavement evaluation. The project was comprised of three main tasks:
Data Collection
The initial task involved the collection of right-of-way roadway images across desired streets and routes in Bowie, Maryland. Transconomy established collection areas using the Manager application, and Transconomy staff captured roadway images at 25-foot intervals utilizing the Collector app on a smartphone mounted on the vehicle's dashboard.
Data Analysis
Once the images were collected, the app synced the images to Transconomy Hub. Here, the images were processed, and Artificial Intelligence (AI) models were applied. These models included a PASER-based pavement condition assessment as well as traffic signs and other point and linear assets such as sidewalks and drainage inlets, to name a few.
Data Delivery
The resulting inventory and condition data were delivered to the city in Transconomy’s Viewer application, allowing for easy web-based access to a visualization of summary and detailed data, and in an ESRI shapefile geodatabase, which could be easily imported into their GIS system for city-wide distribution.
Transconomy performed a complete inventory of our street network including pavement condition and all assets in the right of way. Their commitment to quality and on-time delivery was impressive, and we are currently using this information to make data-driven decisions that will positively impact the citizens in our community.

Results: The results were a pavement condition assessment and an asset inventory delivered to the City of Bowie, aligned to the city’s provided linear referencing system.
Transconomy conducted a comprehensive Pavement Condition Rating (PCR) assessment, employing a custom ranking scale provided by the city. This thorough evaluation assigned ratings to each road within the network, covering a total of 1,104 segments spanning over 400 lane-miles. The analysis encompassed a meticulous inventory process, documenting more than 7,100 signs, 22,000-point assets, and 433 miles of linear features for the city. This data-rich approach ensures a comprehensive understanding of the infrastructure, aiding in strategic planning and maintenance efforts.

The spatial referencing of the data to the city’s roadway network empowers Bowie to conduct both high-level overviews and detailed reviews based on location, asset type, or condition. This analysis facilitates a nuanced understanding of the infrastructure landscape, enabling the city to fine-tune maintenance and operations plans, pinpoint potential risks, optimize allocation of funding and resources, and formulate long-term planning strategies. Transconomy’s low-cost, high-quality solution enabled the City of Bowie to provide an actionable pavement paving plan for the next fiscal year in a fraction of the previously planned time.
