The Ultimate Quiz On GMAT Reading Comprehension Test!

1. According to the passage, what is the greatest challenge facing a state Department of Transportation?

The large volume of private vehicles on the road today.

The age and capacity of the roads and highways.

Accidents and road construction.

The management, integration and presentation of real-time traffic information.

The costs of constructing new roads.

According to the passage: "The management, integration and presentation of the collected real-time information present the greatest challenge to a state Department of Transportation or municipality..."

Explanation

According to the passage: "The management, integration and presentation of the collected real-time information present the greatest challenge to a state Department of Transportation or municipality..."

2. According to the passage, how is real-time traffic information collected in the TRANSMIT program?

From driver registration data.

Toll tag readers measure the travel time of tag holders between readers.

Driver data is entered into the system when drivers pass a toll booth.

Driver data is logged when drivers enter and exit the system.

Drivers are located using RFID tags.

According to the passage: "The successful TRANSMIT program in the NY/NJ area uses roadside toll tag readers to measure the travel time of tag holders between readers." Providing information about volumes and routes are helpful, but it is also valuable to measure time between known points in a real-time traffic management system.

3. Why were cell phones not very successful in the Washington DC test?

They could not accurately measure a driver's speed.

They could not distinguish between traffic slowdowns and deliberate stops on the part of the driver.

People would not consent to participate in the test.

Most people turn their cell phones off in the car.

Reflections and obstructions prevented a good measurement of drivers' locations.

According to the passage: "Inaccuracies due to radio frequency reflections and obstructions to line of sight prevented the desired degree of precision in locating vehicles"

Explanation

According to the passage: "Inaccuracies due to radio frequency reflections and obstructions to line of sight prevented the desired degree of precision in locating vehicles"

4. From the information in the passage, what is the critical element in an intelligent transportation system?

Reliable construction updates.

Real-time transportation system information.

Sufficient Federal funding.

Mature cellular networks.

Inductive loop detection devices

The passage states: "Real-time transportation system information is the critical element in the development of intelligent transportation systems (ITS)."

5. Why is the use of probes interesting to traffic planners?

The probes can be placed in areas where other data collection methods fail.

Probes can be moved from place to place.

Probes are less expensive than other types of traffic counting devices.

Probes provide a wider range of information than other traffic counting devices.

Information can be captured over multiple links or over various time periods.

According to the passage: "Probes in the system provide the ability to measure performance over space, including the capture of information over multiple links or segments over various time periods." Being able to look at the information in many different ways over time allows for better analysis of traffic movement.

6. What advantage might the TRANSMIT program have over traditional data collection methods?

The TRANSMIT system can measure travel time of particular drivers.

A large number of drivers can be tracked.

The TRANSMIT system comes with a "ready-made" set of participants.

Drivers can report real-time traffic conditions.

TRANSMIT tags can be tracked from aerial surveillance patrols.

Each of the TRANSMIT drivers represents an opportunity to collect data on real-time traffic movement.

Explanation

Each of the TRANSMIT drivers represents an opportunity to collect data on real-time traffic movement.

7. What drawback might cell phone geolocation pose?

Not every driver carries a cell phone.

Cell phones cannot provide precise location information.

Cell coverage is not uniform in a metropolitan area.

Driver privacy.

Cell phone companies may not be willing to cooperate with the study.

Cell phones can be attributed to an individual. There is some reason to believe that an individual could be identified or targeted
