Bottleneck Ranking helps you identify problem locations and allows you to prioritize proposed projects. Ranking is performed using a dozen different factors including queue length, number of occurrences, impact, and accumulated delay.
For each bottleneck location, Bottleneck Ranking allows you to dive deep into the data to see exactly when and where congestion is occurring and to link in event data to help you determine why.
CHART Reporting is a custom analytics package built on top of data collected from the Maryland CHART System’s ATMS software, which includes data about traffic events, DMS, CCTV and other devices, and operator logs. CHART Reporting provides information useful for real-time operations and for analysis of performance over long time periods. Reports can be scheduled within CHART Reporting, which allows for automatic emailing of key performance metrics to interested parties on regular intervals. CHART has found this particularly useful during severe weather events, when keeping the public and key decision makers up-to-date is vital, and automating this task allows the CHART operators to focus their attention on addressing the problems at hand instead of compiling and mailing out reports.
With Congestion Scan you can analyze conditions on one or more stretches of road. With the multi-road feature, you can stitch together roadways for a continuous route to better analyze commuter, recreational, or freight corridors. A traffic events layer allows you to visualize any relationships between congestion and incidents, work zones or other adverse situations.
Using the Dashboard you can create widgets that allow you to keep tabs on real-time conditions or monitor your progress toward FHWA’s MAP-21 target setting requirements.
Speed and Travel Time widgets will keep you up-to-date in real-time as conditions change on roadways you’re monitoring. Historic conditions are displayed alongside the real-time data to help you recognize if deteriorating conditions are abnormal for the current time of day and day of week.
Ranked bottleneck widgets display all of the active bottlenecks across a region, their lengths, and their duration so far.
The MAP-21 widgets allow you to input the thresholds your state or MPO will be using for MAP-21 reporting and will display your progress toward meeting those targets over the course of the year and on a per-segment basis.
Detector Tools - Detector Profile
The Detector Profile displays readings and health data for a single detector for up to a three month period. The time slider allows you to start at the macro, multi-month, leveland zoom into the micro, per-minute, level, allowing you to identify patterns and deviations from those patterns in speed and volume data.
The Detector Profile works with both single- and multi-lane detectors.
Detector Tools - Health Summary
Traffic detectors, being physical devices, are subject to damage, network outages, and miscalibration. The Detector Tools Health Summary displays the current and historic health of the entire detector system and allows you to drill into each region, road, and even the individual detector level to see exactly which areas need the most attention to improve the reliability of the detectors therein.
Detector Tools - LaunchPad
The Detector Tools LaunchPad displays a list and map of every traffic detector from which RITIS consumes data. It allows you to select a subset of those detectors to openin either the Detector Profile, Road Profile, or Health Summary, and allows you to download raw data from the sensors.
Detector Tools - Road Profile
The Detector Tools Road Profile allows you to analyze congestion metrics from detectors installed along a specific corridor, including travel time, travel time index, andbuffer time index. This can help you understand the reliability of the performance of the roads on which detectors are installed.
Event Query Tool
All traffic event data collected by RITIS is archived indefinitely, and the Event Query Tool allows you to search that archive. In addition to allowing you to find individual events that match your search criteria, the Event Query Tool also provides charts displaying trends and maps displaying high-frequency event locations.
Explore and Visualize Crashes (EVC)
Analyzing safety data to determine the cause of accidents and identify high-accident locations helps to improve road safety and reduce accident severity. Accident recordscontain a vast amount of information describing almost every aspect of a collision; however, mining accident data tables requires an extensive knowledge of queryinglanguages and familiarity with the data itself. Explore and Visualize Crashes provides a web interface that removes many of the barriers to effectively understand accident datasets. Through a series of visualizations (some traditional, some unique to the domain of accident data), Explore and Visualize Crashes allows users to effectively piece togetherthe stories that underlie their accident data.
Alerts can be configured to notify you (SMS or email) whenever an event that matches certain parameters occurs within an area you’re interested in. This can be particularlyhandy for monitoring high-demand routes or even your own personal commute. You can choose during which times of day you want to be notified and how severe an incidentneeds to be in order to trigger an alert.
Incident Clustering Explorer (ICE)
The Incident Clustering Explorer allows you find correlations between different attributes of a large set of traffic events. For example, there is a high correlation between the number ofvehicles involved and the total duration of an event. Using the correlations the Incident Clustering Explorer makes apparent, you can infer how the resolution of future events might occur.
The Incident Overview combines the features of the Incident List and the RITIS Map, allowing you to simultaneously sort and filter while maintaining the context of the plethora of datamade available through the robust layering system of the map.
The Incident Timeline provides for the visualization of detailed real-time and historic traffic management center incident data. The detailed history of a traffic event, whichoften include hundreds of data points, can be viewed in a graphical, one-screen overview. Line color, thickness, and length work together to convey data that wouldnormally take multiple pages and large tables to understand. The Incident Timeline reduces the chance of missing critical information, enables the user to correlate events,and reduces the time needed to comprehend the many simultaneous events that occur or occurred during the management of one or more incidents.
The MAP-21 tool set includes capabilities to compute, visualize, and download all of the PM3 Metrics and sub-metric data as required to be reported by FHWA.Agency speed-limit data can be integrated, and trend-line capabilities are already helping agencies more easily address target-setting requirements. Soon to becompleted: an “easy button” will allow agencies to immediately create all of the necessary files and deliverables to FHWA for compliance.
Note: Through a competitive procurement process, AASHTO awarded a contract to a team led by the CATT Laboratory (with INRIX and the Texas Transportation Institute) to make this set of tools available to agencies through AASHTO’s Transportation Performance Management pooled fund study.
Massive Data Downloader
Use the Massive Data Downloader to export large amounts of probe data for offline analyses. You can select any combination of road segments (an entire region, set of corridors, zip codes, etc.), and any date range and time of day. In addition to raw or aggregated data, you can include quality indicators and other measurements
The NPMRDS is a probe data set commissioned by FHWA and produced by the CATT Lab for use for free by DOTs and MPOs for use in their MAP-21 performance reports. The NPMRDS is powered strictly by probe readings, so if no vehicles are on a segment during a particular 5-minute reporting period, the NPMRDS has an empty record for that period. The NPMRDS Coverage Map lets you explore the prevalence of these empty readings with filters for time of day and type of vehicle.
Use Performance Charts to prepare reports using a variety of visualization techniques – bar, line, scatterplot and candlestick – representing aggregate conditions across a road for key performance metrics. 5th/95th and 25th/75th percentiles ranges help underscore the significance of deviations from the norm.
The Probe Data API allows developers to run the same queries that power the Probe Data Analytics Suite and then consume the results. The API exposes endpoints for road search, data exports, performance metric computation, and user delay cost analysis.
Region Explorer allows you to explore the relationships between bottlenecks and traffic events and their impacts on traffic conditions in real-time or points in the past. The Region Explorer’s map provides a geospatial context for the data it presents, and the table lists all of the events and bottlenecks within the bounds of the map, allowing you to arrange the map around your area of interest and sort the list to determine which traffic events and bottlenecks are causing the most impact for the traveling public.
Developers can use the RITIS Filter API to access the event and device data collected by RITIS. Flexible filtering allows for very specific queries to be run, which can be used by developers to create dashboards, notification systems, or a wide variety of other applications.
RITIS Incident List
The RITIS Incident List displays a sortable and filterable list of every active event tracked by RITIS, and it is kept up-to-date in real-time. Set your filters appropriately, and the RITIS Incident List becomes your one-stop dashboard for prioritizing event response for the critical active events your operations team is dealing with at any given time.
The RITIS Map presents more than a dozen real-time geospatial data feeds, providing more information about the transportation system than data available in most ATMS systems by a large margin. Event data from each agency, DMS locations and their current messages, traffic detectors with real-time charting for their speeds and volumes, probe speed data, and weather radar data are just a few of the real-time data sets made available through the RITIS Map.
RITIS Meeting is collaborative platform built on top of the core features of the RITIS Map. It is highly scalable — supporting 600+ simultaneous participants In addition to the features found on the RITIS Map, RITIS Meeting provides a set of tools to facilitate collaboration among participants. Hosts can relinquish control to presenters, poll the audience about how a particular traffic problem should be addressed, share files, and annotate the RITIS map.
With Speed Alerting you can set a threshold speed limit or percentage of the free flow speed and receive an email or text message when that threshold is reached. You can delay notifications until a threshold is breached for a certain period of time to prevent normal fluctuations in speeds from generating false alarms.
Speed Threshold Breakdown
Speed Threshold Breakdown allows you to see the amount of time in which speeds were above or below certain threshold values for an arbitrary date range or geography. This is useful for making sure your roads are meeting your performance targets.
Video streams from hundreds of highway CCTV and patrol units’ dashboard cameras are pumped through RITIS every day. Our Traffic Cameras application allows users to watch individual streams or build a custom “video wall” to display dozens of feeds simultaneously. A map adjacent to the video wall provides the geospatial context for the feeds.
TrafficView gives the general public access to the core features of the RITIS map, Traffic Cameras, and Incident Alerts while stripping out a lot of the tools that (while useful for agency users) don’t provide much utility to the traveling public. Real-time speed data, incident data, and traffic cameras provide travelers with the information they need to make decision about how best to utilize the transportation options available to them.
Many data sets can be represented by a progression of trees over time. The federal budget with its departments and agencies, each with different amounts of funds available to them year after year, the hierarchy of states and counties and individual roads and the bottlenecks that occur on them each year, and the incidence of various diseases across a hierarchy of demographics are a few examples. Because of changing structures in trees over time, these data sets can be difficult to conceptualize mentally as they change over time. Treeversity solves this.
Treeversity is an interactive visualization tool that allows for the comparison of two trees with topological changes or value changes in nodes. It uses several different visualization techniques to convey the differences between trees over time, and introduces a novel glyph, the bullet, to show absolute change and percent change simultaneously. A zoomable treemap allows for exploration of particularly dense trees, and textual summaries provide for insights to be plucked from the tool with minimal interaction required.
Trend Map allows you to create animated maps of probe data performance metrics over the course of time. This can be useful for seeing exactly when conditions deteriorate during morning and evening rush hour.
Up to seven maps of different time periods can be plotted side-by-side, which facilitates before-and-after comparisons for workzones, signal timing changes,or other TSMO projects expected to yield a change in roadway performance.
Trend Maps can be embedded in external websites, allowing you to easily share the results of your findings with non-RITIS users.
By combining probe speed data, volume data, and economic function to set a value for an average person’s time, we can determine how much money is lost by delay on the road way. This provides sound footing as you attempt to justify the cost of a proposed construction project or TSMO initiative.
Results are displayed in a table by hour of day and date, which can help you pinpoint when incidents and recurring congestion take their toll on the traveling public.
Proper training of first responders is essential for effectively managing the consequences of traffic incidents, but the cost of training is high, and — while there can be no substitute for hands-on experience — real-life training for emergency circumstances can be dangerous.
Our Virtual Incident Management Training course is a two-part program designed to give first responders the most realistic training experience in a virtual setting. The first part is a web-based core competencies course meant to educate responders on best practicesfor safely conducting themselves at an incident scene.
The second part is a MMORPG where each trainee logs into a virtual world and assumes the role of a first responder. A trainer can configure accident scenes throughout the world with a wide array of hazards, and the trainees, from the safety of their desks, can manipulate their avatars to respond to the accidents. The trainer has an omnipotent view of the virtual world and can offer feedback on the responders’ actions and replay the scene from any angle.
Virtual Weigh Station
Virtual Weigh Station provides agencies that use weigh-in-motion detectors with a window into their data. Enforcement personnel can sit downstream of the weigh station with the real-time Virtual Weigh Station monitor pulled up on their toughbook or mobile device and receive alerts, including photos and weight data, of vehicles in violation of weight restriction. This allows for quick decision-making as to whether or not to flag down offending vehicles.
The Virtual Weigh Station’s archival tools allow managers to search for trends and repeat offenders and make decisions about the best time to deploy their enforcement personnel.
Work Zone Performance Monitoring Application
Manage work zone impacts in your state through a dashboard style interface. A profile page for each work zone allows you to dynamically assess current conditions, past conditions, and user cost impacts. The alerting systems allows you to receive email or text message notifications whenever certain speed or bottleneck conditions are met within a work zone.
4D Virtual Globe
The 4D Virtual Globe application weaves real-time geospatial data from different sources into one coherent virtual environment. This visualization tool has been developed to provide incident management personnel, emergency management personnel, and the general public with the means to achieve situational awareness in as close to a real-world setting as possible. The 4D Virtual Globe is the next best thing to buying each traffic operations center staff member a personal helicopter (and it’s a lot safer, too).
