2818 / H ARVE Y MITCHELL P ARKWAY ALTERNATIVE TREATMENTS SCORING Alternatives Treatments Scoring Methodology This technical memorandum describes the methodology and results of a scoring and prioritization evaluation of alternative improvements for the FM 2818 Harvey Mitchell Parkway corridor in Bryan/College Station, Texas for each of the five segments A through E. The Alternative Treatments defined for Segments A through E were evaluated based on their contribution to the defined vision for the corridor as revealed in the Technical Advisory Committee (TAC) survey. Evaluation criteria were developed to measure how well each alternative performs. Three criteria were developed from the TAC survey from the responses that received more than the median value of votes. These criteria were important to TAC members in defining the issues and focus areas for the corridor. Three additional evaluation criteria were added to form a more comprehensive scoring. The six evaluation criteria are defined as: A. Enhances Safety – Safety is the top-scoring criteria on the TAC survey, with an average score of 4.6 votes out of 5. B. Improves Mobility & Congestion – Concerns about mobility and congestion had an average score of 4.2 votes on the TAC survey. Mobility was consistently rated as more important than access in defining the function of the corridor. C. Accommodates Cross Traffic - With an average score of 2.8, accommodating traffic crossing the corridor was seen as important by the TAC. The evaluation considered crossing traffic from motor vehicles and active transportation modes. D. Consistent With Regional and Local Plans - This additional criterion considers whether an alternative is consistent with established transportation plans such as comprehensive plans, thoroughfare plans, and bicycle & pedestrian plans. E. Implementation – This additional criterion evaluates any issues or necessary construction that must occur before an Alternative Treatment
