Alliance was called in to develop a solution for the Killeen-Temple (KTMPO) and Waco Metropolitan Planning Organization (MPO) areas in 2014. These MPOs are adjacent, geographically, but are separate entities in need of separate plans. The Alliance team analyzed the possibilities and created a plan to develop their travel demand models concurrently, on a very aggressive schedule, to meet the MPOs’ planning needs.
The travel demand models produced by the Alliance team enabled the MPOs to identify the problem areas in their region and work to correct them. Our work on these projects built upon our previous work. We were able to deliver the models more quickly and with more advanced features, including the ability to predict intersection delay and to forecast traffic by time of day.
Alliance was able to help identify challenges for other MPO efforts as well, such as their Congestion Management Plan (CMP). Our efforts gave planners a way to analyze different scenarios and to present those to the public and to policy makers. The tool we developed also enhanced the MPOs’ public engagement efforts.
The KTMPO and Waco MPO models were developed based on a standard TxDOT 3-step model using TripCAL5 (TxDOT trip generation software), ATOM2 (TxDOT trip distribution software), and TransCAD 6.0 with a base year of 2010 and forecast year of 2040.
The project involved the review and update of the KTMPO and Waco MPO base and forecast roadway networks and traffic analysis zones (TAZ) to TxDOT standards. The demographic and employment data for each MPO were reviewed individually to verify that the data was consistent with industry standard data sources. The model input data was also compared to verify compatibility between the models for future analyses that transvers both model areas. The models were calibrated and validated to best practice standards with appropriate calibration and validation checks performed and documented at each step of TDM development. Sensitivity tests were developed, run, and documented as part of the validation effort, as well.
Alliance led this effort as part of the CH2M-Hill Team. Together we were able to build an alliance that created solutions for the Killeen-Temple (KTMPO) and Waco Metropolitan Planning Organization (MPO) areas.
