TL;DR
This paper addresses the problem of routing for asthma patients by integrating real-time environmental data with personalized health profiles. It introduces a health-aware routing framework that uses an enhanced A* heuristic, where the decision function is $\mathbf{R}(i,t) = f(\mathbf{A}_i, \mathbf{W}(t), \mathbf{T}(t))$ and the safety-aware objective is $r_{\text{safe}} = \arg\min_{\mathbf{r}} \left( \sum_i d(\mathbf{r}_i) + \alpha h_{\text{env}}(\mathbf{r}_i,t,\mathbf{A}_i) \right)$; $f(\mathbf{r}_i) = g(\mathbf{r}_i) + h_{\text{env}}(\mathbf{r}_i,t,\mathbf{A}_i)$. Using SUMO simulations and real-time data from the Microsoft Weather API, the approach demonstrates improved asthma-risk avoidance with only modest increases in computation time compared to traditional Dijkstra routing. The work's key contributions include a formal problem formulation, a data-acquisition and routing pipeline, and empirical evidence that health-aware heuristics can yield safer, more personalised routes in dynamic urban environments, with implications for public health and urban planning. Future extensions could incorporate forecasting via machine learning, long-term health considerations, and global deployment to broaden applicability.
Abstract
Asthmatic patients are very frequently affected by the quality of air, climatic conditions, and traffic density during outdoor activities. Most of the conventional routing algorithms, such as Dijkstra's algorithm, usually fail to consider these health dimensions, hence resulting in suboptimal or risky recommendations. Here, the health-aware heuristic framework is presented that shall utilize real-time data provided by the Microsoft Weather API. The advanced A* algorithm provides dynamic changes in routes depending on air quality indices, temperature, traffic density, and other patient-related health data. The power of the model is realized by running simulations in city environments and outperforming the state-of-the-art methodology in terms of recommendation accuracy at low computational overhead. It provides health-sensitive route recommendations, keeping in mind the avoidance of high-risk areas and ensuring safer and more suitable travel options for asthmatic patients.
