The Department of Transportation and Capital Infrastructure (DTCI) historically acted in a responsive mode with regards to reported safety deficiencies and/or operational problems at roadway intersections. To enhance responsiveness in addressing safety and operational problems at intersections, DTCI developed the Roadway Intersection Improvement Program. This program provides a data-driven process to systematically identify problematic intersections to preempt incidents or complaints. This program involved conducting an inventory of non-signalized, signalized, and roundabout intersections along roadways listed in the Countywide Transportation Plan (CTP) and non-CTP roadways of significance. Currently, this program evaluated intersections based on traffic volumes and crash history. From this data, the intersections are ranked on a scale from one (1) through five (5) where a ranking of 5 represents the most critical intersections requiring improvements and a ranking of 1 indicates the lowest priority intersections. This presentation will provide an overview of the Loudoun County Roadway Intersection Improvement Program.

The past 12 months have been anything but ordinary for transportation. From the unprecedented decline in travel (and mode shifts) due to COVID-19, to unexpected natural disasters like hurricanes and wildfires, transportation experts are scrambling to make sense of it all and keep their communities safe. Luckily, thanks to advances in big data resources derived from mobile devices, innovative use of Census data, and extensive research, experts can both continue their normal work and conduct studies they’ve never had the capabilities to before, all from the safety of their home or office.
In this presentation, Juliet Hirni of StreetLight Data will show attendees how to leverage big data to gain insights into unexpected changes in travel patterns. The presentation will begin with an explanation of how location data derived from mobile devices is obtained and processed into transportation metrics, followed by examples of how to use these metrics to perform routine projects during transportation upheavals: deriving reliable volumes, turning movements, O-D, AADT, VMT, and other core metrics.
Juliet will also show how big data can be used to study the impact of events like COVID-19 on traffic, travel patterns, toll revenues, and more. For each example, the focus will be on the type of data that engineers use to accomplish their goals, and the specific insights planners glean from the data.
By the end of the session, attendees will walk away understanding how analytics derived from mobile devices can help transportation experts continue their work amidst unusual circumstances, and analyze the effects of the circumstance itself. We’ll wrap up the discussion by opening the floor for questions about using big data for transportation planning, with the goal of enabling attendees to conduct critical, comprehensive evaluations of big data resources for their own projects.

The District Department of Transportation (DDOT), supported by the Mead & Hunt consultant team, completed the traffic signal optimization of the Downtown section of DC, improving multimodal traffic flow at over 640 intersections, in November 2019. The project was a necessity in order to enhance the District’s multimodal transportation system; increase pedestrian safety throughout the region; to accommodate changes in travel patterns and volumes that have emerged from regional growth and development activities; and to coordinate newly installed traffic signals into the overall system. The goals of the project were to make DC traffic signals safer and friendlier for pedestrians and bicyclists; maintain bus running times and delays; and to accomplish these goals while minimizing negative impacts on traffic operations throughout the District.
In order to advance the District’s Vision Zero goal, the project team incorporated multimodal safety and mobility goals into the traditional signal optimization framework. As such, the team reimagined what the goals of a signal optimization project could be and used this opportunity to implement multimodal improvements on a large network-wide scale. The use of a signal program in such a manner ensures improvements are proactive, equitable, and efficient to implement as the enhancements are directly incorporated as part of the overall re-timing effort. Through automatic network-wide evaluations of treatments like LPIs, pretiming, and more, every signal that has been retimed has been evaluated for enhancement without waiting for citizen requests or a safety issue to materialize. This proactive approach has the potential to significantly improve safety by mitigating crashes before they occur. It is also more equitable than the traditional engineering approach used by many cities where “the squeaky wheel gets the grease.” Engineers can implement these treatments where truly needed before people even ask, and in all eight wards of the District.
While many of these changes would typically come at the expense of vehicular progression and delay, the project team leveraged their experience to minimize these impacts, essentially regaining all of the vehicular capacity lost to LPIs, pretiming, and other multimodal improvements. As a result, the team helped to create a more welcoming multimodal environment where community members and visitors can safely walk, ride, and thrive.

This study introduces a novel integrated school bus problem that considers sequential operation of fleet for all three levels in a unit framework. An algorithm based on the simulated annealing (SA) method was developed to find the optimal routes based on minimization of school buses’ operating cost and total student traveling time. An example on a hypothetical network was developed and tested to demonstrate the developed algorithm. The algorithm successfully handled the integration of school buses’ optimal route generation while it met all constraints. The results showed that the routings by the integrated single framework algorithm can save the total costs by 4.5% to 12.4% compared to the routings with the separated level algorithm. Also, it showed that the total costs of the integrated routing framework for different morning and afternoon time windows are 8.28% less than the same routings (identically reversed) for morning and afternoon time window.

New transportation technologies and shared mobility systems have not only disrupted the market but also revolutionized the way mobility is perceived. In order to build more accessible and sustainable future, it is important to investigate how shared mobility is being used, and how socio-demographic and health factors affect users’ behaviors and usage likelihoods. Specifically, a few different modes that include bike-sharing, ride-sourcing, shared automated vehicles (SAVs), and peer-to-peer (P2P) carsharing were evaluated to gain more insights into the heterogeneity of their users. This work applied data-driven analysis to understand perception, adoption, usage, and concerns of emerging technologies and shared mobility. Additionally, the relationship between health and transportation was examined and it was determined how health-related variables impact transportation decisions on an individual level

The reauthorization of the FAST Act expires in 2021. The FAST Act built upon the previous surface transportation legislation, MAP-21, which was passed in 2012, with minimal changes to the novel MAP-21 requirements for State DOTs and MPOs to begin to utilize quantitative performance measures in the Transportation Planning process. Existing legislation states that consistent performance measurement should help monitor system and agency performance and relate performance to the decision-making process over time. Thus, the next surface transportation authorization should build upon the MAP-21/FAST Act performance measure requirements while maintaining standards to collect and report uniform data. Updating performance measures can support the incoming administration’s focus on climate and energy and further leverage the progress made at the state and regional levels.
This presentation will show results of a 2018 study on how MPOs responded, if at all, to the changes in transportation planning requirements set forth in MAP-21 regarding performance measure development; the effect of Federal mandates; available and desired resources; and data utilization in the planning process. It will then review recent plans and bills from congress and executive branch leaders and present priorities and recommendations for the next federal surface transportation authorization. Lessons learned from this research can inform future efforts to develop and refine performance measures in the transportation planning process.
