Average Annual Daily Traffic (AADT) measures the total volume of vehicle traffic on a roadway for a year divided by 365 days.

These levels can help transportation planners and other agencies anticipate where roadway resurfacings and reconstructions are going to be needed in the upcoming years.

Looking at this particular measure on the region’s roadways, almost all federal aid system roadways measure as high volume, seeing 3,001 or more vehicles on the roads per day.



Capital Area Transit (CAT) provides fixed route transit service to Cumberland and Dauphin Counties, with the City of Harrisburg serving as the major hub in the system. The Market Square transfer center, located at the intersection of Market and 2nd Streets, is the primary transfer center. The Derry Township Intermodal Transportation Center in downtown Hershey is a major park and ride location, providing over 600 parking spaces and access to both CAT and Lebanon Transit service.

CAT is currently conducting a complete review and redesign of their fixed–route service network. As part of that process, a State of the System report, which provides an assessment of existing service and identifies opportunities and challenges, and Market Analysis report, which evaluates and identifies transit market demand, were created. These documents provide valuable insights into existing and potential service areas and are available at the links above. As the CAT 2020 Network Redesign is finalized and implemented, the changes in the system will be reflected in this plan.

The urban areas of York, Lancaster, and Lebanon are served by their own transit authorities. York County’s Rabbittransit provides express service to and from downtown Harrisburg. Lebanon Transit provides service to downtown Harrisburg and Hershey. Lancaster County’s Red Rose Transit Authority does not currently provide service to the HATS region. Improving the service and coordination with surrounding transit providers is a high priority long term goal for the HATS region.

The CAT fixed route system is supported by 35 park and ride facilities. Some are formally identified and maintained by PennDOT and/or CAT; some are established through agreements with retailers and shopping centers; and some are informal locations near popular transit stops. Not all park and ride facilities are dedicated to transit use; locations outside the CAT service area serve car- and van-pool users.

Published in December 2010, the HATS Upper Dauphin and Perry Counties Park and Ride Project study examined existing and potential park and ride facilities and provided recommendations. A similar study should be conducted to identify possible park and ride locations in the more developed areas immediately surrounding the City of Harrisburg, possibly as part of the recommended long-term transit system planning or transit development plan.

Shared Rid/Paratransit service is provided in Dauphin County by CAT and in Cumberland and Perry Counties by rabbittransit. These services, with recommendations for each geographic subregion, are covered extensively in the HATS Coordinated Public Transportation – Human Service Transportation Plan.

The map at right shows shared ride pick-up/drop-off locations. Both pick-ups and drop-offs are evenly distributed throughout the HATS region. Improving the coordination between the centrally managed and located shared ride hubs and the geographic dispersed location of their users will be key to improving efficiencies in the shared ride system.




Commuter Services of PA is a professionally staffed organization whose purpose is to reduce traffic congestion and pollution by helping commuters find alternatives to driving alone. Their service area covers 9 counties, including Cumberland, Dauphin, and Perry Counties, in south central Pennsylvania, and nearly 1.2 million commuters living or working in those counties. The organization is funded by federal Congestion Mitigation & Air Quality (CMAQ) funds and overseen by the Susquehanna Regional Transportation Partnership, which consists of local chambers, transit agencies, and planning agencies. Across their many services, Commuter Services of PA assists employers and individuals with information and/or coordination related to car- or van-pools, transit and train, walking and biking, and telecommuting.

Road Diets are becoming increasingly popular in communities across the country as a way to address critical transportation needs without significant capital investment. While the exact design and configuration can vary based on a variety of factors, the typical Road Diet involves converting a four-lane, undivided roadway to a three lane roadway with improved accommodations for non-motorized road users. Road Diets represent excellent “bang for your buck”, often requiring little investment beyond repainting for implementation, yet significant safety benefits by calming traffic through the reduction of travel lanes and reducing collisions by providing a dedicated left turn lane. Additionally, the space gained by eliminating one travel lane can be used to provide dedicated, buffered bicycle lanes or wider shoulders, depending on the characteristics of the road.

Road Diets are not effective for all roads, particularly those with average daily traffic exceeding 20,000 vehicles. Further study and cooperation with municipalities will be required to identify implementation opportunities. 


  • Consider access to transit -- and related bicycle and pedestrian accommodations -- a high priority in areas identified for growth in the RGMP;

  • Work with CAT and other area transit providers on long-term planning efforts to improve service access and efficiency within the HATS region and surrounding communities;

  • Identify and pursue additional park and ride facilities throughout the HATS region;

  • Conduct system-wide analysis during next update of Coordinated Public Transit -- Human Service Transportation Plan;

  • Continue supporting Commuter Services of PA and other community organizations providing transportation services to residents of the HATS region through funding, coordination or planning assistance.

  • Conduct further analysis and work with municipalities to identify opportunities for Road Diet implementation
