Four I’s of Good Traffic Data
Integrity. Data that is timely, accurate, complete and verifiable.
Information. Data integrity, along with transportation engineering expertise, leads to better and more accurate assumptions.
Intelligence. Further expertise, knowledge, and other tools allow for the intelligent use of Information. This is the basic building block of sound engineering judgment.
Informed Action. Well assembled and supported Intelligence leads to informed action by decision makers.
Implications of Bad Traffic Data
Poor Execution. With bad data, engineering and infrastructure projects have a weak base to start from - resulting in projects that exceed timelines, budgets and compromise results.
Compromised Results. Poorly executed projects lead to lower than anticipated Level-of-Service (for example); and ultimately affect the Engineering Firm’s reputation.
eg. Signal Timing Plan: Under-reported volume can lead to shorter signal phases, and create long queues. Over-reported volumes result can result in increased delay for certain movements.
Complaints & Problems. Traffic delays, accidents, and overall driver frustration will persist soon after project completion.

Example: BRAC North VirginiaHeadline News:$1 Billion BRAC mistake: Traffic upends plans for 6,400-person facility - Federal Times, October 2010
The Defense Base Closure and Realignment Commission (BRAC), is directed at closing excess military facilities and reducing overall expenditures. In 2005, this process would move about 6,400 workers from the Pentagon to the new Department of Defense Headquarters at the Mark Center in Alexandria, Virginia.
Once the $1 billion facility was constructed, heavy traffic congestion was immediate. It was later determined that faulty traffic data was used and the location did not have the infrastructure or transit to support this influx of people. It was selected as it was the lowest bid.
What was the damage?• Only 1,000 parking spaces were built for
nearly 6,400 personnel.• Lack of supporting infrastructure and no
access to nearby Metro or Rail stations.• Level-of-Service was severely compromised on
6 major intersections in Alexandria.• An additional $100 million are going towards
improvements ($20M DoD; $80M VDOT).

Importance of Data IntegrityTimely. Simply applying a growth factor to historical data can severely reduce accuracy, especially with other factors such as economic downturn, or increased commercial development.
Accurate. Accurate data is the foundation for all Engineering Projects. Without a solid foundation, project recommendations, execution, and outcomes will falter.
Complete. Having complete data helps draw a more accurate picture of project requirements. For example, vehicle classifications & pedestrian data offer a complete picture of an intersection.
Verifiable. How will you know your traffic data is accurate? Having the ability to review data abnormalities provides supporting evidence to recommendations and piece-of-mind.
“ ”Decisions about major public investments to the sum of hundreds of thousands of dollars are predicated on data.

signal Timing: What to Improve
The main reasons for a Signal Timing project are a symptom of delay:• Improve two-way progression, performance at
intersecting arterials;• And in turn, reduce fuel consumption,
emissions, travel time and driver complaintsBy addressing these areas, we’re hoping to improve Level-of-Service.
Common Goal:
Reduce Delay at Peak Periods

signal Timing: What to Collect
Cities are now becoming increasingly multi-modal and drivers share the roads with other users.
Collecting data and improving service is a balanced evaluation of the trade-offs between priority of all users’ needs.

Data Collection is just the first piece of the puzzle. There are a few standard reporting formats that are used in our industry by various modeling software including PDF, Excel, CSV, PetraPro format and Synchro format.
Depending on the data collection method, data input to these software may have to be done manually, or can be extracted directly from the device or tool.

Webinar Poll: Data Collection for CorridorsWhen collecting data for corridors, the best-case scenario is to collect same-day data. This will ensure consistency, and typically eliminate the need for day-over-day data balancing. However, due to a lack of resources or equipment, this is usually difficult.
To determine how webinar attendees get around this challenge, we gathered input on how they collect data for large corridor projects, and which simulation software they use.

Corridor BalancingData accuracy among intersections is very important for signal coordination along a corridor. Even small variances can have a significant impact.
Traffic flow can be influenced by sources and sinks along a road segment, which is why it’s very important that vehicular flow is accurate between adjacent intersections.
In order to ensure accuracy, Miovision completes a first-pass software comparison of outbound volumes against inbound volumes. This is done to highlight any discrepancies (such as large spikes or valleys) which need to be corrected before moving to the next phase.

Michigan Large scale signal Optimization
Below is a customer case study for URS which will illustrate Miovision’s impact on data collection projects and corridor studies. URS used Miovision and manual methods to collect traffic data for their Western Ottawa Michigan large-scale signal retiming project.
The objectives of the project were in-line with the objectives of many other signal re-timing projects across the country.

1. Two intersections used to compare accuracy of methods.
2. Manual validation using video as source.The numbers show that Miovision and Manual Counting were quite close in accuracy – varying no more than 3% of total traffic volume.
While the accuracy is within acceptable range for both methods, this shows how Miovision is a viable alternative to even the best manual counters.

TIs: 24hr Intersection & segment Count
Engineering firms can utilize either in-house or outsourced solutions to collect arterial volumes and intersection counts for traffic impact studies.
Collecting a 24-hour TMC with segment volumes is a time and cost effective method for collecting this data. Receive an intersection report for peak hours during the 24 hour time period along with an export for each arterial volume, totaling five reports. Vehicle classification including bicycle, pedestrian and transit are available.

24hr Intersection & segment Volume Count
Manual method includes laying road tubes or using numetrics which are both highly intrusive. Data accuracy cannot be verified and it provides four 24-hour volume and classification reports.
To collect data with a video solution, you can either collect this data in-house using the appropriate hardware or outsourcing it to a vendor that utilizes video hardware.
Video is a non-intrusive data collection method that provides a video record, which can be utilized for quality assurance. With Miovision, users would receive a 24-hour intersection report which you can extract peak-hour information along with four volume reports, all with vehicle classifications. Plus a video recording that can be reviewed and provide additional insight in the intersection.

Tech Comparison: AlburyCity
Steve Swann from AlburyCity tested Miovision’s Video Collection Unit in a Central Business District which experienced high volumes and delay at lunchtime that got progressively worse over the week.
For the intersection counts, Steve tested Miovision against volumes from the already-installed SCATS system, and a manual counter, counting from video.
For the mid-block counts, Steve tested Miovision against tubes, SCATS and a manual counter.
Steve found Miovision to be very accurate, and safer than tubes. He also mention that SCATS was useful for providing phase and cycle information at signals.

The City of Edmonton was tasked with updating their Transportation Master Plan to encourage multi-modal transportation and move away from drive-alone vehicles.
The Plan called for additional performance measurements to benchmark improvements, which included longer Turning Movement Counts; Trails, Paths and Walkway Counts; Arterial Classification counts; and Generational Counts in focus neighborhoods.
As the chart shows, Edmonton cut their costs in half using Miovision, allowing them to free-up budget while eliminating their backlog. The City of Edmonton continues to grow their count program with Miovision.

Bicycle and Pedestrian information is used for planning and designing a solution which incorporates multi-modal transportation within a corridor, but this data is often overlooked in the planning process even though it is an important piece of a Complete Street project.
Miovision can provide real and accurate data on all modes of transportation along with a video record of existing pedestrian and bicycle activity which exists in the corridor. This video record often proves to be beneficial when presenting findings to their clients and the general public.

Video records help communicate data, traffic, and any anomalies with other stakeholders who commonly are not engineers: such as councilors, government officials, and citizens. It also provides a historical record that can be reviewed at a later time.
One of our customers, Gordon Meth from the RBA Group, states that his organization greatly benefits from the video. They use it to win projects, for any kind of educational sessions or classes, and in public meetings for projects. The video and video stills are highly effective and provide more insight than reports and charts, especially for non-technical individuals.

I’ve actually used the video tape during interviews to win projects, while teaching a class on teaching the fundamentals of saturation flow rate, and in public meetings on projects to show the dynamics of what’s going on in a way that is far, far more effective than any of the reports and charts I used to use.

Outsourcing: Without MiovisionOutsourcing traffic data collection can be a very time consuming process. This process is actually comprised of numerous steps which I’ve broken down into these six time blocks.
All of these steps together average about 7.5 hours of coordination for data collection. This is basically one full day of work, but of course, when working with other people, their responses are not instantaneous. Firms might not reply to you in a timely manner or you might have an on-going case of phone tag.
Whatever the case, this average time of 7.5 hours, or even longer, can be put to better use.

Intersection CountA tally of all vehicular, bicycle and pedestrian movements at an intersection.
Road and Highway VolumeA count of vehicle and bicycle volume at a road segment.
Roundabout CountThe total sum of turning movements from origin to destination within a roundabout.
Vehicle Gap DataA measure of headway time between vehicles on a road facility.
License Plate DataA time-stamped capture of the license plate of each vehicle passing a location.
51
summaryData: Foundation for Engineering Applications Importance of high data accuracy• Accurate data is the foundation for
engineering applications. It’s important to use data with integrity and in order to have that, you need the ability to validate it.
Data collection for signal timing, corridor progression, traffic impact studies• There is now a trend for data collection to
incorporate all modes of transportation for any data projects including signal timing, corridor progression and traffic impact studies. This allows all of the road users, such as bikes and pedestrians, to be incorporated into any project plans.
Integrating with Miovision• Miovision provides users with accurate, timely
data using both in-house and outsourced options. Our solutions aim to make the best use of your resources, including time and money, so that you can concentrate on completing your projects rather than collecting data.
