3.2.2.1 Corridor-wide Operational Improvements The following operational improvements are recommended for the entire corridor. � Develop truck friendly lanes with weigh in‐motion and signal priority vehicle control technology A major corridor need is to provide travel capacity for both passenger vehicles and large trucks hauling freight. Accommodating heavy truck volumes and general purpose traffic volumes can be a challenge. Throughout the study, stakeholders and the public consistently listed high volume truck traffic SR 6 as a concern for safety and congestion. The ARC Regional Freight Mobility Plan indicated overall in the Region, total freight tonnage is projected to increase by 78 percent between 2005 and 2030. 5 Within the SR 6 corridor study area, the Norfolk Southern Whitaker Intermodal Terminal is slated for expansion. According to Norfolk Southern officials, the Terminal is built out at 60 percent, so a planned full build‐out of the facility will send more large trucks onto SR 6. In order to provide some separation between large trucks and general purpose traffic, it is recommended that the outside lane on SR 6 in each direction be widened to 13 feet. The wider outside travel lane would increase the buffer between the outside lane and adjacent lanes. The wider outside lanes would be coupled with Intelligent Transportation System (ITS) technologies as appropriate: weigh‐in‐motion detection and signal priority. These technologies could decrease congestion, delay, and red light running for trucks at signalized intersections along the SR 6 corridor with roadway grades that are five percent or greater. Possible technologies for consideration include wireless magnetic sensors or in‐ground sensors. Wireless magnetic sensors are able to identify vehicle classification, vehicular speeds, and traffic volumes and can be adapted to modify green time at signalized intersections. In‐ground fiber optic load sensor systems detect when the balance of traffic volumes in stopped condition exceeds a defined threshold and changes the traffic signal at the intersection. These systems address congestion relief and truck signal priority in order to reduce idling and delays and prevent red light running. 5 Atlanta Regional Commission, Regional Freight Mobility Plan, page 9.

� Conduct a corridor‐wide traffic operations assessment For the SR 6 Corridor Study, traffic operations were reviewed on a planning‐level basis, which means a limited amount of new or existing data was reviewed on a macro level to identify major needs. Only a few intersections were identified for more detailed examination due to safety reasons or responding to public comment. However, from traffic engineering field visits conducted in the SR 6 corridor, it was determined that a comprehensive traffic operational assessment was needed. As the corridor has made a relatively quick transition from rural to urban travel patterns and from moderate to heavy traffic volumes during commute times, the corridor needs to serve its current and future role a regional commuter and freight thoroughfare. Specific items that should be reviewed and assessed are signage, pavement markers, traffic controls, location and placement of raised medians, and suitability for large truck travel. Field review and public input indicate a need for a comprehensive examination of signage to improve wayfinding and operations. Stakeholder comment received following the draft recommendations indicated a need for raised medians throughout the corridor. Some signage is distracting; other signs are obstructed. At some intersections, pavement markings could be extended to lengthen storage capacity where pavement is present. Traffic controls should be optimized. The design characteristics of SR 6 intersections should be evaluated, with an emphasis on providing safe and trouble‐free movement of trucks through the corridor. Characteristics such as curb radii, grade, and sight distance should be investigated. Larger curb radii could allow more room for trucks to maneuver and potentially decrease delay at intersections. Trucks are affected by grade, particularly when accelerating or decelerating. The sight distance needed for safely passing, stopping, and turning for large trucks should be provided throughout the corridor, particularly at intersections and access points. � Develop a Share the Road Program Many passenger vehicle drivers are uncomfortable driving in the vehicle mix with numerous large trucks, as is the case along the SR 6 corridor. A Share the Road Program can assist in increasing public awareness about limitations on trucks such as longer stopping distances, blind spots, slower acceleration, and large turning radii. Increasing awareness and educating the public can be done through pamphlets, signage, enforcement, and even interactive programs. Final Report 3‐18 January 2008
