SR-55 (1-5 to SR-91) PAED <br />This project is to prepare traffic study in support of the SR-55 (1-5 <br />and SR-91) widening PA/FD in Orange County. Jinghua is leading <br />all the modeling related effort and providing future traffic volume <br />forecasting for various alternatives in support of traffic operations <br />report. <br />SANDAL Urban Area Transit Strategy <br />This project is to assist SANDAG in updating the long-range <br />regional transit plan to reflect new technologies including <br />driverless vehicles and transportation network companies. Fehr & <br />Peers led the technical analyses including advising SANDAG on <br />performance measures, travel demand modeling approaches to <br />reflect new technologies, and completing a travel markets <br />analysis and updates to the proposed transit and ITS investments <br />in corridors throughout the region. Jinghua Is leading the travel <br />demand modeling associated with the analyses, including setting <br />up model parameters and procedures to reflect the impact of <br />new technologies in demand forecast, developing off -model <br />procedure to estimate the use of the modes that are not <br />included in the SANDAG ABM, including microtransit and <br />ridesharing modes, as well as generating required performance <br />measures. <br />Caltrans Transportation Modeling/Forecasting Service <br />This project is to provide on -call model development and <br />updates to the California Statewide Freight Forecasting Model <br />(CSFFM) in order to better integrate the results with the <br />passenger forecasts from the California Statewide Travel Demand <br />Model (CSTDM). Jinghua assists in enhancing the base year 2012 <br />model, including the update of submoddes to forecast truck trip <br />table and the subsequent procedures such as assignment <br />procedure, and model validation. <br />RCTC Truck Study, Development and Implementation <br />of Regional Logistics Mitigation Fee <br />As part of a team, Fehr & Peers is assisting RCTC in determining <br />the level of impact of warehousing and logistics activities on the <br />Riverside County highway system, the proportional amount of a <br />fee to mitigate these impacts, and documenting the nexus for a <br />fee program. Jinghua supported the interpretation of the <br />regional model in forecast growth in logistics facilities through <br />2040. <br />South OC Mobility Study <br />This project is to assist the local toll agency (TCA) in evaluating <br />mobility options for South OC. This effort has included working <br />with a variety of stakeholders to define a range of future mobility <br />treatments focusing on SR-241 connection and local facility <br />improvement, testing those treatments via technical analysis to <br />see how they perform, and reporting the results to the team for <br />their consideration. Jinghua led all the modeling related tasks <br />including toll/HOT demand forecasting and provided technical <br />information to gain the confidence of all participants in the <br />objective. <br />San Bernardino County Transportation Analysis Model <br />(SBTAM) Modeling Support <br />Jinghua has supported SBTAM since 2014. She provided <br />modeling support for SANBAG's Countywide Transportation Plan <br />(CTP), leading the effort to develop SBTAM 2040 scenarios, and <br />performing scenario analysis for both highway and transit sides. <br />In addition, Jinghua assists the clients to maintain SBTAM and <br />enhance its functionalitles. <br />OCTAM FTA New Starts Update <br />Jinghua was the key modeler to update OCTA's mode choice <br />model to meet FTA guidelines for models intended to support <br />projects seeking funding from the New Starts program. Jinghua <br />was responsible for the model review, generating calibration <br />targets and leading the effort to develop and fully implement the <br />model updates. The emphasis of the model updates was on the <br />mode choice model, including the revision of the nesting <br />structure following current best practice models and by <br />introducing new transit modes (e.g., BRT and high-speed rail), the <br />corresponding update of utility calculations, auto calibration <br />procedure, and reporting functions. <br />OCTAM Modeling Support <br />Jinghua was the project manager to help update OCTAM <br />TransCAD, from input preparation to model enhancement. <br />Jinghua was responsible to manage the project, and in charge of <br />OCTAM model updates, including revision to the model zone <br />structure, highway and transit network, as well as the <br />improvement of the GISDK code to streamline the model <br />processes and enhance functionalities of OCTAM TransCAD. <br />SCAG Activity -based Model Development and <br />Validation in Support of the 2016 RTP/SCS <br />Jinghua was the key modeler in developing SCAG's Activity - <br />Based Model (ABM). Starting from the model developed in the <br />previous stage, an extensive re -specification of the model was <br />performed, to advance the ABM to the point where it is a <br />practical tool that supports the 2016 RTP and other regional <br />planning needs. <br />SCAG Mode Choice Model Enhancement and Regional <br />Model Update <br />Jinghua was the key modeler to help enhance SCAG's Trip -Based <br />Model (TBM), including application of 4D concepts to the SCAG <br />regional model, mainly to the mode choice model, vehicle <br />availability, and trip generation models, and other model <br />components. <br />RFP NO.: 21-125 37 <br />
