From page 36... ...
Spring 2002 Metropolitan areas are growing rapidly and their congestion is creating sticky rides on the national highway system. Over 75% of the United States population now live in urban areas.
|
From page 37... ...
Spring 2002 incidents are handled but their impacts can be catastrophic and trigger gridlock on the freeways. The urban areas of the United State have experienced tremendous population growth over the past 10 years.
|
From page 38... ...
Spring 2002 Incident management involves the systematic use of human and mechanical processes. The primary goals of the Kansas City Incident Management Program, in addition to saving lives and property, is to minimize the effects of such incidents on traffic congestion and reduce the possibility of secondary incidents.
|
From page 39... ...
Spring 2002 An incident that causes delay on a freeway can be as simple as a disabled vehicle in the traffic lane or on the shoulder. It can be a lost piece of lumber from a truck that causes motorists to change lanes suddenly.

Spring 2002 agencies, it was decided that all parties would have to work together. With this in mind, the Kansas City Incident Management Plan has worked toward these goals: • to develop better coordination among organizations.
|
From page 46... ...
Spring 2002 The accurate identification of equipment and personnel needed at an incident site significantly decreases the time required to clear the incident. Proper identification of needs at an incident site is more of a function of training and knowledge of the available resources than a function of technology.

From page 47... ...
Spring 2002 Effectiveness is doing the right things right - - combining well-trained rescues with good strategy and tactics. But, what pulls all this together and makes it run smoothly and therefore economically is good management.
|
From page 48... ...
Spring 2002 • Traffic control – In order for traffic to move smoothly and safely past the incident; traffic control needs to be established at the scene. If lanes or roadway will be closed, traffic needs to be channelized to merge into lanes or shoulder that will remain open.

From page 49... ...
Spring 2002 DEPARTMENT OF TRANSPORTATION (DOT's) : They are typically responsible for: • Assisting in incident detection and verification.

From page 50... ...
Spring 2002 No consistent standard has been identified that can be uniformly applied to evaluate the quantifiable benefits of an effective incident management program. In any case quantifiable benefits generally associated with an effective incident management program include: • Increased survival rate of crash victims.

Incident Management Study Wilbur Smith Associates It is important to note that facilities that have a high volume to capacity ratio may not necessarily surpass the congestion threshold, and vice versa. Low volume facilities may be congested due to excessive turning movements, a proliferation of access points, excessive signal cycle lengths, poor signal coordination, and/or poor signal phasing.
