There are two maps in this graphic:

1. PM Peak Traffic Delays in 2003 by Type of Delay
   This map shows a map of the central part of the region, with roads, cities, and bodies of water. The main highways are overlaid with a wide, dark line representing the recurring delay on the corridor. The width of the line is proportional to the number of delays per month. A lighter shaded line next to the dark line represents the delay due to incidents, with the width again proportional to the number of delays per month.
2. PM Peak Period Planning Time Index in 2003
   This graphic shows a map of the central part of the region, with roads, cities, and bodies of water. The main highways are overlaid with a wide, shaded line representing the base travel time on the corridor. A darker line is drawn next to this line to represent the additional travel time drivers need to factor into their plans in order to account for non-recurring congestion. This width of this line varies with the amount of additional time needed.
