The Lehigh Valley Planning Commission (LVPC) is seeking a qualified consultant to provide expertise on work tasks described in this Request for Proposals (RFP) for the development, maintenance, operation of and training for the use of the Lehigh Valley Regional Travel Model. The LVPC is the regional planning agency for the Lehigh Valley, Pennsylvania which includes Lehigh and Northampton counties. The Lehigh Valley is comprised of 62 municipalities including the cities of Allentown, Bethlehem and Easton, 27 boroughs and 32 townships.

The LVPC, along with PennDOT and LANta, serves as staff for the Lehigh Valley Transportation Study (LVTS), the metropolitan planning organization (MPO) for the Lehigh Valley. The role of LVTS is to promote transportation plans, programs and policies that are consistent with the Lehigh Valley Transportation Plan in accordance with Federal law. LVTS
maintains a continuing, comprehensive and cooperative transportation process consistent with the comprehensively-planned development of the urbanized area in order to be eligible to receive Federal transportation funding. The regional travel model is an important tool for the LVPC’s transportation planning and is used in analyses for project planning, project prioritization, long range needs, congestion management, and air quality, to name a few.

The LVPC uses the Cube Voyager modeling platform to perform regional travel model analyses. The software simulates both highway and transit conditions. The model also uses Central, an overriding run management software package, and two post-processing software packages associated with air quality analyses (PPAQ and PPSUITE). EPA’s MOBILE 6.2 air quality software is currently used for air quality conformity determinations of Lehigh Valley transportation plans and programs. However, the conversion to the next generation MOVES software is anticipated to occur over the next year. The Lehigh Valley’s 730 square miles are divided into 473 traffic analysis zones (TAZs). The LVPC will provide socio-economic inputs through 2040 for the model. The model had last undergone a full calibration to a base year of 2000.
