Pavement Management

Pavement management is the process of planning the maintenance and repair of a roadway network or other paved infrastructure to improve road conditions throughout the network. It is also used on runways and airports. Every highway superintendent undertakes walkway management. Traffic management includes the cost of living cycles in a systematic way of repairing minor and major roads and reconstruction projects. The needs of the entire network and budget estimates are considered before the projects are undertaken, as the cost of data collection can change significantly. Pavement management incorporates many of the features and functions required to maintain the quality of the paved material as well as to ensure that the entire road network can sustain itself at the required levels. Although pedestrian management involves the life cycle of commuting from planning to maintenance of any transport infrastructure, road asset management, and road maintenance planning is primarily aimed at road infrastructure.

Please USE 3.0 instead of 2.5 for the rolling terrain. Thanks! 6.20 A divided multilane highway in a recreational area has four lanes (two lanes in each direction) and is on rolling terrain. The highway has 10-ft lanes with a 6-ft right-side shoulder and a 3-ft left-side shoulder. The posted speed is 50 mi/h. Previously, there were 4 access points per mile, but recent development has increased the number of access points to 12 per mile. Before development, the peak- hour factor was 0.95 and the directional hourly volume was 2200 vehicles with 13% heavy vehicles. After development, the peak-hour directional flow is 2600 vehicles with the same vehicle percentages and peak-hour factor. What is the level of service before and after the development?
