Introduction

As urban environments continue to evolve, ensuring the safety and efficiency of pedestrian travel becomes increasingly paramount. Accurate estimation of pedestrian volume plays a crucial role in urban planning, transportation management and road safety initiatives. Traditional methods of pedestrian volume estimation, such as travel surveys and street view images, provide valuable insights but are often resource-intensive and may lack spatial and temporal granularity. In this perspective article, we propose a novel approach leveraging bus dashcam videos and deep learning techniques to estimate pedestrian volume, offering a cost-effective and scalable solution with the potential to revolutionize pedestrian data collection and analysis. Dashcam videos offer a wealth of visual data that can be leveraged to estimate pedestrian volume with high accuracy and granularity. Unlike traditional methods such as travel surveys or street view images, dashcam videos provide real-time insights into pedestrian activity, capturing dynamic changes in volume and behavior. By employing advanced computer vision and machine learning techniques, researchers can extract pedestrian volume data from dashcam videos with comparable, if not better, performance in explaining crash frequency. One of the key advantages of dashcam-derived pedestrian volume analysis is its ability to identify risk factors associated with road segments, both with and without pedestrian crossings [1].

Description

Bus dashcams offer a unique vantage point for capturing real-world pedestrian activity along urban roadways. By strategically deploying dashcams on buses traversing diverse routes, we can collect a wealth of video data depicting pedestrian movements in various urban contexts. These videos serve as rich sources of information, capturing pedestrian volume, behavior and interactions with the built environment in real-time. Leveraging this vast repository of data presents an unprecedented opportunity to develop robust pedestrian volume estimation models with high spatial and temporal resolution [2]. Deep learning techniques, particularly Convolutional Neural Networks (CNNs), have demonstrated remarkable capabilities in analyzing visual data and extracting meaningful patterns. By training CNN models on annotated bus dashcam videos, we can teach them to recognize and quantify pedestrian activity with high accuracy. These models can learn to detect and track pedestrians across different scenes, lighting conditions and weather conditions, yielding reliable estimates of pedestrian volume at specific locations and times. To validate the effectiveness of our proposed method, we conduct a comparative analysis with alternative pedestrian volume estimation methods, such as travel surveys and street view images. While these traditional approaches provide valuable reference points, they may suffer from limitations such as sampling bias, data incompleteness and temporal discrepancies. By juxtaposing the estimated pedestrian volumes derived from bus dashcam videos against those obtained from traditional methods, we can assess the accuracy, reliability and scalability of our approach. Accurate estimation of pedestrian volume is critical for identifying high-risk areas and implementing targeted interventions to enhance road safety. By leveraging bus dashcam videos and deep learning approaches, we can gain a comprehensive understanding of pedestrian activity patterns and their relationship to crash frequency. Moreover, our method enables the identification of risk factors on road segments with and without pedestrian crossings, informing the design of safer and more pedestrian-friendly urban environments. By analyzing patterns of pedestrian activity, researchers can pinpoint areas of high pedestrian density, frequent pedestrian-vehicle interactions and potential conflict points. This information is invaluable for identifying risk factors that contribute to crash frequency and informing targeted interventions to mitigate risks and enhance road safety. The insights gleaned from dashcam-derived pedestrian volume analysis have significant implications for road safety initiatives and urban planning efforts. By identifying high-risk areas and understanding the factors driving pedestrian-vehicle conflicts, transportation agencies and policymakers can prioritize resources and implement targeted interventions to improve safety outcomes. This may include installing traffic calming measures, enhancing visibility at pedestrian crossings and improving infrastructure to accommodate pedestrian activity. Moreover, dashcam-derived pedestrian volume data can inform the development of predictive models to anticipate crash hotspots and proactively address safety concerns. By integrating real-time pedestrian volume information with other traffic data sources, such as vehicle volumes and crash history, transportation agencies can develop proactive strategies to reduce the likelihood of pedestrian-related crashes and improve overall road safety.

Conclusion

In conclusion, the utilization of dashcam videos to derive pedestrian volume data represents a promising avenue for advancing road safety research and practice. By harnessing the power of advanced computer vision and machine learning techniques, researchers can gain unprecedented insights into pedestrian activity patterns and associated risk factors. Armed with this knowledge, transportation agencies and policymakers can take proactive steps to create safer, more pedestrian-friendly environments for all road users. As we continue to innovate and refine our methodologies, we move closer to achieving our shared goal of zero pedestrian fatalities on our roadways.
