The usual intercity traveler moves slowly through the station area. The passenger may not be familiar with the routine, have baggage to handle and check or retrieve, have a long wait for connections or delayed trains, and may require information, food, and a comfortable place to sit. Commuters, on the other hand, are familiar with the route through the station, have little or no luggage, and are usually in a hurry. They want direct access to or from local streets and transport. These two types of traffic should be kept separate to avoid conflict and confusion. In some large stations such as Grand Central Terminal in New York City, commuter and intercity trains arrive and depart on different levels. In smaller stations, separate platforms should be used and traffic routed so that the two lines of movement do not cross. In some instances, separate stations are in use. Clear and concise direction and routing signs and other means of channelization are desirable.
