As can be seen in the table above, the construction cost for each component was calculated. Using the table, it was found that total construction cost would be $518,000. It was also found that the time for construction would be six to seven months.

Pavement Design
For the purpose of this corridor, the pavement was designed such that one uniform pavement design could be used throughout the bounds of the project. The pavement design was completed using the Marshall method as described in the Mannering and Washburn textbook, and based on the traffic count data provided by the NJDOT. By performing this analysis, it was found that the optimal design consists of five inches of hot mix asphalt, five inches of coarse soil cement, and eleven inches of crushed stone.

Second Update – Traffic Counts
Monday, the group used the NJDOT website to find traffic count data for the site. The traffic count data was found for 24 hour periods in six different locations. This data will be used to create the optimal design for the intersections as well as for traffic signal optimization. In addition charts were created for each location. An example of this can be seen below.
