We used synthetic datasets on real road works (Oldenburg) and real datasets from the state of California. ? We varied the total number of categories m, the density per category r, and the work sizes. ? We pare the NN and MD algorithms on road works using Rtrees. Datasets Average Trip Length Query Cost Conclusion ? Introduced a novel query for spatial databases. ? Designed four approximation algorithms with various approximation guarantees. ? Implemented the algorithms in practice using Rtrees for Euclidean spaces and road works. ? Contacted a prehensive experimental evaluation. Thank you!
