Use CV event data together with ML and AI analyses methods to inform Traffic Management Centers (TMC) for making real-time adjustments to alleviate non-recurring congestion. This study pointed out…
Transportation Management Centers are established around the country to integrate data, information, and systems in support of day-to-day traffic and emergency operations. A primary challenge that…
Critical to the on-going success of ITS implementation is an effective operational strategy. Transit agencies seeking to achieve operational efficiency ought to maintain the support they need to keep…
Installation and implementation are critical phases of the deployment path of an ITS project. When dealing with new ITS technologies there are numerous problems that may arise, making it crucial for…
The process of procuring ITS technologies has proven to be one of the most complicated and problematic of deployment phases for many agencies. Perhaps most critical is the selection of a proper…
Establishing a well-specified plan before embarking on any ITS project is key. As is typical with any well-managed project, it is important that during the initial planning process agencies define…
As always, there are issues with funding any transportation project, and ITS in particular, that require recommendations and advice. The transit agencies in this case study brought forward a number…
When deploying ITS to rural transit, there are a number of well-recognized technical processes and applications that should be considered to help ensure its success. There will almost always be…
All ITS projects inherently have a number of institutional and organizational issues that are uncovered during the project deployment. In fact, these issues have often presented the most significant…
Training staff in the use of transit ITS resources is as important, if not even more important, in small rural transit agencies as it is in much larger transit agencies. Smaller agencies cannot…
METHODOLOGY
The prototype model development involved integrating emerging and traditional data sources, such as connected vehicle event data, safety data, probe vehicle speeds, and TxDOT’s ITS…
METHODOLOGY
Overall, this study compared three implementation scenarios with a No Action i.e. do-nothing scenario. These implementation scenarios were:
(1) Electric Bus Scenario:
-12-year life for…
METHODOLOGY
To investigate the association between ridesourcing travel and road safety, the researchers started by aggregating variables by census tract and month-year units. The ridesourcing…
A benefit-cost analysis was performed that considered the benefits of TMC lane-blocking responses and additional signal retiming. All benefits and costs were estimated over…
Results showed that for all metrics studied, the gasoline hybrid-electric (HEV) fleet performed better than EV fleets by providing response times of 4.5 minutes compared to 5.5 minutes (an 18 percent…
Traffic signal pre-emption systems allow a temporary interruption to normal operation of traffic signals to give emergency vehicles priority. This is done by changing traffic signals in the path of…
Upgrading timing infrastructure and retiming corridors to provide improved traffic flow during peak hours in peak directions can result in significant reductions in delay, number of stops, and travel…
The Capital Area Rural Transportation System (CARTS) rural transit Intelligent Transportation Systems (ITS) project uses a sophisticated 900 MHz two-way radio system combined with automated demand…
It has been widely recognized that emerging technologies may improve fleet operations in the transportation sector. This study analyzed both battery-electric buses and self-driving (fully automated)…
Texas Department of Transportation aims to develop a pedestrian and bicyclist count monitoring process to aid several transportation planning projects spanning safety, design and traffic operations.…
Carsharing is the short-term provision of individual vehicles to individuals who drive themselves and return the cars to set locations. It differs from traditional car rental in that most carsharing…
This report presents operational best practices and related technology for applying ITS to rural transit. The data is based on case studies/interviews conducted at five transit agencies:The Capital…
