Rapid urbanization and population growth have put great pressure on urban infrastructure and services. Current urban planning requires powerful strategies and innovative planning to modernize urban life.

Policymakers and city officials are exploring solutions to provide new services in an efficient, responsive, and sustainable manner for a large population.
