Dependencies in transportation
Improving transportation infrastructure and services are a high priority for many cities. As they plan improvements they will want to be cognizant of the interdependencies between   transportation systems and energy and communications systems as well as the built environment.  The connection between transportation and the built environment is straightforward – roads, rails and ports are typically  essential components of a smart transportation system – but can also represent massive construction investments.
Beyond cost considerations, the various modes of transport all require power and communications to function properly within a smart transportation environment – especially true as cities move to electrified light rail or buses and set up recharging infrastructure for electric vehicles. 
Benefits of smart transportation 
In the highlights that follow you’ll get a better understanding how smart transportation improves a city’s  livability, workability and sustainability:
Reducing traffic and congestion. Advanced analytics and instrumentation can provide cities with the information they need to minimize congestion. Traffic lights can be synchronized and adjusted for optimal traffic flow. In-vehicle collision-avoidance systems can take action to prevent congestion-causing accidents. Incident detention and notification systems can analyze information from cameras and vehicles to detect traffic problems, alert drivers and suggest alternative routes. Parking can be made more efficient through instrumentation and mobile apps. 

Reducing trip time. With the help of analytics and ICT, traveler information systems and real-time route planning can plot multi-modal routes for travelers. Smart city transportation networks direct people when and where to switch from a bus to the subway, for example, to arrive at destinations at the lowest cost or fastest time. And traffic and weather alerts can be delivered via smartphone applications to alleviate commute times.

Empowering people with choice and control. Smart transportation gives people the power to make better transportation decisions. In smart cities, multi-modal fare cards are used to pay for all forms of city transportation or parking. And data gathering instrumentation and open data policies empower them with their own transportation information. People create ridesharing apps to optimally pair passengers and drivers, neighborhood-specific parking and traffic maps, apps that publish
wait times for parking lots and so on. 
Improving public safety. Smart transportation has a strong link to public safety. First responders require mobility to perform their lifesaving work, and ICT can make their jobs easier by optimizing traffic lights when necessary and empowering them to see potential traffic snarls in real time so they can select the most efficient travel routes.
