Virginia Smart Road

Virginia Smart Road is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Virginia Smart Road rather than just read about it. In short: The Virginia Smart Road, also known as simply the Smart Road or Smart Highway, is a short, limited-access road in Montgomery County, Virginia, used for the testing of pavement technologies and as a proving ground for new transportation technologies. The road is not open to the public.

Key takeaways

Virginia Smart Road belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Virginia Smart Road to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Virginia Smart Road from memory before moving on to harder problems.

Reference excerpt

The Virginia Smart Road, also known as simply the Smart Road or Smart Highway, is a short, limited-access road in Montgomery County, Virginia, used for the testing of pavement technologies and as a proving ground for new transportation technologies. The road is not open to the public. The Smart Road is currently a 2.2-mile (3.5 km) stretch of road with turn-around loops at either end. Eventually, the road will be extended to a total of 5.7 miles (9.2 km), directly connecting U.S. Route 460 in Blacksburg to Interstate 81 with an interchange near mile marker 121; however, there is yet to be a set time frame for completion. The Wilson Creek Bridge was built for the Smart Road and, at 175 feet (53 m) tall, is the second tallest bridge in Virginia. The road and bridge are operated and maintained by the Virginia Department of Transportation. It is part of the proposed Interstate 73 Corridor.

Features Smart Road features and operations include, but are not limited to:

A 2.2-mile, controlled-access test track built to interstate standards Two paved lanes Three bridges, including the Smart Road Bridge (the second tallest state-maintained bridge in Virginia) Full-time staff that coordinate all road activities 24/7 access control and oversight Centralized communications Lighting and weather system controls Safety assurance and surveillance Fourteen pavement sections, including an open-grade friction course In-pavement sensors (e.g., moisture, temperature, strain, vibration, weigh-in-motion) Zero-crown pavement section designed for flooded pavement testing An American Association of State Highway and Transportation Officials (AASHTO)-designated surface friction testing facility Seventy-five weather-making towers accessible on crowned and zero-crown pavement sections Artificial snow production of up to four inches per hour (based on suitable weather conditions) Production of differing intensities of rain with varying droplet sizes Fog production Two weather stations with official National Oceanic and Atmospheric Administration (NOAA) weather available within one mile Variable pole spacing designed to replicate 95 percent of national highway systems Multiple luminaire heads, including light-emitting diode (LED) modules A wireless mesh network variable control (i.e., luminaire dimming) A high-bandwidth fiber network A differential GPS base station Complete signal phase and timing (SPaT) using remote controls Wide shoulders for safe maneuvering during experimental testing

Segments

In 1994, VDOT unveiled two alternate routes for the Smart Road partially to avoid smooth purple coneflower populations in Ellett Valley.

Worked examples

Example 1 — a first encounter with Virginia Smart Road

Start with the simplest possible case. Write down what Virginia Smart Road claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Virginia Smart Road before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Virginia Smart Road ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Virginia Smart Road

In research: Virginia Smart Road appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Virginia Smart Road in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Virginia Smart Road is common in secondary-school and first-year university syllabi. It links to neighbouring topics Intelligent transportation systems, Roads in Virginia, Southern United States road stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Virginia Smart Road outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
