Abstract:Mobile light detection and ranging (lidar) technology offers a significant opportunity to increase transportation safety and efficiency. However, most commercial systems are prohibitively expensive for usage with consumer products like bicycles and in widespread implementation throughout our transportation infrastructure. Therefore, cost-effective lidar systems are needed and this effort describes the development of two options targeted for different safety outcomes. The first option involved the generation of a lidar system that can create three-dimensional point clouds with upwards of 700,000 data points as a cost of less than $300. Initial results highlight its potential in monitoring pavement quality as an example of its capability in providing data for transportation-related reports. The second option built on prior electric bike (e-bike) lidar testing efforts and created a similarly cost effective two-dimensional lidar system that was able to capture the interaction of an e-bike with surrounding motor vehicles. Overall, both options require further refinement before extensive deployment can take place. Nonetheless, this work demonstrates that low-cost lidar systems are a prospective route for enhancing safety within the transportation environment.
