The complexity of modern traffic management extends far beyond mere road monitoring, encompassing massive amounts of data collected worldwide from connected cars, mobile devices, roadway sensors, and major event monitoring systems. For transportation authorities managing urban, suburban, and rural traffic flow, the challenge lies in effectively processing and acting upon this vast network of information. The task requires balancing immediate operational needs, such as real-time traffic redirection during incidents, with strategic long-term planning for improved mobility and safety.

Traditionally, analyzing these complex data patterns and producing actionable insights has been a resource-intensive process requiring extensive collaboration. With recent advances in generative AI, there is an opportunity to transform how we process, understand, and act upon transportation data, enabling more efficient and responsive traffic management systems.

In this post, we partnered with Amazon Web Services (AWS) customer INRIX to demonstrate how Amazon Bedrock can be used to determine the best countermeasures for specific city locations using rich transportation data and how such countermeasures can be automatically visualized in street view images. This approach allows for significant planning acceleration compared to traditional approaches using conceptual drawings.

INRIX pioneered the use of GPS data from connected vehicles for transportation intelligence. For over 20 years, INRIX has been a leader for probe-based connected vehicle and device data and insights, powering automotive, enterprise, and public sector use cases. INRIX’s products range from tickerized datasets that inform investment decisions for the financial services sector to digital twins for the public rights-of-way in the cities of Philadelphia and San Francisco. INRIX was the first company to develop a crowd-sourced traffic network, and they continue to lead in real-time mobility operations.

In June 2024, the State of California’s Department of Transportation (Caltrans) selected INRIX for a proof of concept for a generative AI-powered solution to improve safety for vulnerable road users (VRUs). The problem statement sought to harness the combination of Caltrans’ asset, crash, and points-of-interest (POI) data and INRIX’s 50 petabyte (PB) data lake to anticipate high-risk locations and quickly generate empirically validated safety measures to mitigate the potential for crashes. Trained on real-time and historical data and industry research and manuals, the solution provides a new systemic, safety-based methodology for risk assessment, location prioritization, and project implementation.

Solution overview

INRIX announced INRIX Compass in November 2023. INRIX Compass is an application that harnesses generative AI and INRIX’s 50 PB data lake to solve transportation challenges. This solution uses INRIX Compass countermeasures as the input, AWS serverless architecture, and Amazon Nova Canvas as the image visualizer. Key components include:

Countermeasures generation:
INRIX Compass generates the countermeasures for a selected location Amazon API Gateway and Amazon Elastic Kubernetes Service (Amazon EKS) manage API requests and responses Amazon Bedrock Knowledge Bases and Anthropic’s Claude Models provide Retrieval Augmented Generation (RAG) implementation
Image visualization
API Gateway and AWS Lambda process requests from API Gateway and Amazon Bedrock Amazon Bedrock with model access to Amazon Nova Canvas provide image generation and in-painting

The following diagram shows the architecture of INRIX Compass.

INRIX Compass for countermeasures

By using INRIX Compass, users can ask natural language queries such as, Where are the top five locations with the highest risk for vulnerable road users? and Can you recommend a suite of proven safety countermeasures at each of these locations? Furthermore, users can probe deeper into the roadway characteristics that contribute to risk factors, and find similar locations in the roadway network that meet those conditions. Behind the scenes, Compass AI uses RAG and Amazon Bedrock powered foundation models (FMs) to query the roadway network to identify and prioritize locations with systemic risk factors and anomalous safety patterns. The solution provides prioritized recommendations for operational and design solutions and countermeasures based on industry knowledge.

The following image shows the interface of INRIX Compass.

Image visualization for countermeasures

The generation of countermeasure suggestions represents the initial phase in transportation planning. Image visualization requires the crucial next step of preparing conceptual drawings. This process has traditionally been time-consuming due to the involvement of multiple specialized teams, including:

Transportation engineers who assess technical feasibility and safety standards Urban planners who verify alignment with city development goals Landscape architects who integrate environmental and aesthetic elements CAD or visualization specialists who create detailed technical drawings Safety analysts who evaluate the potential impact on road safety Public works departments who oversee implementation feasibility Traffic operations teams who assess impact on traffic flow and management

These teams work collaboratively, creating and iteratively refining various visualizations based on feedback from urban designers and other stakeholders. Each iteration cycle typically involves multiple rounds of reviews, adjustments, and approvals, often extending the timeline significantly. The complexity is further amplified by city-specific rules and design requirements, which often necessitate significant customization. Additionally, local regulations, environmental considerations, and community feedback must be incorporated into the design process. Consequently, this lengthy and costly process frequently leads to delays in implementing safety countermeasures. To streamline this challenge, INRIX has pioneered an innovative approach to the visualization phase by using generative AI technology. This prototyped solution enables rapid iteration of conceptual drawings that can be efficiently reviewed by various teams, potentially reducing the design cycle from weeks to days. Moreover, the system incorporates a few-shot learning approach with reference images and carefully crafted prompts, allowing for seamless integration of city-specific requirements into the generated outputs. This approach not only accelerates the design process but also supports consistency across different projects while maintaining compliance with local standards.

Amazon Nova Canvas for conceptual visualizations

INRIX developed and prototyped this solution using Amazon Nova models. Amazon Nova Canvas delivers advanced image processing through text-to-image generation and image-to-image transformation capabilities. The model provides sophisticated controls for adjusting color schemes and manipulating layouts to achieve desired visual outcomes. To promote responsible AI implementation, Amazon Nova Canvas incorporates built-in safety measures, including watermarking and content moderation systems.

The model supports a comprehensive range of image editing operations. These operations encompass basic image generation, object removal from existing images, object replacement within scenes, creation of image variations, and modification of image backgrounds. This versatility makes Amazon Nova Canvas suitable for a wide range of professional applications requiring sophisticated image editing.

The following sample images show an example of countermeasures visualization.

In-painting implementation in Compass AI

Amazon Nova Canvas integrates with INRIX Compass’s existing natural language analytics capabilities. The original Compass system generated text-based countermeasure recommendations based on:

Historical transportation data analysis Current environmental conditions User-specified requirements

The INRIX Compass visualization feature specifically uses the image generation and in-painting capabilities of Amazon Nova Canvas. In-painting enables object replacement through two distinct approaches:

A binary mask precisely defines the areas targeted for replacement. Text prompts identify objects for replacement, allowing the model to interpret and modify the specified elements while maintaining visual coherence with the surrounding image context. This functionality provides seamless integration of new elements while preserving the overall image composition and contextual relevance. The developed interface accommodates both image generation and in-painting approaches, providing comprehensive image editing capabilities.

The implementation follows a two-stage process for visualizing transportation countermeasures. Initially, the system employs image generation functionality to create street-view representations corresponding to specific longitude and latitude coordinates where interventions are proposed. Following the initial image creation, the in-painting capability enables precise placement of countermeasures within the generated street view scene. This sequential approach provides accurate visualization of proposed modifications within the actual geographical context.

An Amazon Bedrock API facilitates image editing and generation through the Amazon Nova Canvas model. The responses contain the generated or modified images in base64 format, which can be decoded and processed for further use in the application. The generative AI capabilities of Amazon Bedrock enable rapid iteration and simultaneous visualization of multiple countermeasures within a single image. RAG implementation can further extend the pipeline’s capabilities by incorporating county-specific regulations, standardized design patterns, and contextual requirements. The integration of these technologies significantly streamlines the countermeasure deployment workflow. Traditional manual visualization processes that previously required extensive time and resources can now be executed efficiently through automated generation and modification. This automation delivers substantial improvements in both time-to-deployment and cost-effectiveness.

Conclusion

The partnership between INRIX and AWS showcases the transformative potential of AI in solving complex transportation challenges. By using Amazon Bedrock FMs, INRIX has turned their massive 50 PB data lake into actionable insights through effective visualization solutions. This post highlighted a single specific transportation use case, but Amazon Bedrock and Amazon Nova power a wide spectrum of applications, from text generation to video creation. The combination of extensive data and advanced AI capabilities continues to pave the way for smarter, more efficient transportation systems worldwide.
