| 摘要： | This study quantifies the impact of placing ramp meters along an interstate in Atlanta, Georgia. The segment analyzed includes 11.5 miles of I-75 located 11 miles north of down town Atlanta. Atlanta already has 5 ramp meters and this paper studies the feasibility of placing 5 new ramp meters. Thus, using past & present data the projected ramp meter additions along the corridor were simulated. The complete 11.5 miles of corridor was analyzed as an integrated and interdependent system to determine the impact of different ramp meter configurations. These configurations vary in ramp meter location and timing. The study documented a 2 to 5 minute reduction in travel time (depending on the ramp meter configuration). This reduction in travel time generates a cost saving range between $116,000 and $907,000 per year. The cost saving was calculated only due to the reduction in travel time (this study did not take into consideration fuel consumption or effects on air quality). The cost saving was then related to the capital investment on ramp meter. A single capital investment of $40,000 per ramp meter was considered. This $40,000 does not include any ramps geometric changes. An amortized value over the $40,000 and annual operating cost of $6,050 were used to obtain the benefit/cost ratio for one year. The benefit/cost ratio resulted between 2.3 and 20.8. This wide spectrum of benefit/cost ratio is correlated with the wide range of ramp meter configuration possible in 11.5 miles of highway. |
