What would be the range of impact of an individualized travel marketing program that covers 200,000 workers in Denver by 2022? The program would inform workers about mass transit options. Assume each worker drives 17.5 miles one way, 5 days a week with an average fuel economy of 18 mpg, before this program. What changes may be expected? Report the range of gasoline savings you would expect across Denver

To determine the range of gasoline savings expected across Denver from an individualized travel marketing program, we need to calculate the potential impact on commuting habits based on the given information.

1. Calculate the total distance travelled per worker in a week:
Distance travelled per day: 17.5 miles * 2 (round trip) = 35 miles
Distance travelled per week: 35 miles * 5 days = 175 miles

2. Calculate the total fuel consumption per worker in a week:
Fuel consumption per week: 175 miles / 18 mpg = 9.72 gallons

3. Calculate the total fuel consumption for all workers in Denver in a week:
Total fuel consumption: 9.72 gallons * 200,000 workers = 1,944,000 gallons

Assuming the individualized travel marketing program successfully encourages workers to switch to mass transit options, we can expect a significant reduction in fuel consumption. However, it is difficult to precisely determine the adoption rate and fuel savings for this hypothetical program, so we will provide a range of potential gasoline savings.

The range of gasoline savings may depend on various factors, including the effectiveness of the marketing program, the availability and convenience of mass transit options, individual preferences, and other external factors. Here are some possible ranges of gasoline savings:

- Low estimate: Assuming a conservative adoption rate, let's consider a 10% shift from driving to using mass transit. This would result in a potential fuel savings of 10% of the total fuel consumption:
Low estimate gasoline savings: 1,944,000 gallons * 0.1 = 194,400 gallons

- High estimate: In an optimistic scenario where the marketing program is highly successful, let's consider a 50% shift from driving to using mass transit. This would result in a potential fuel savings of 50% of the total fuel consumption:
High estimate gasoline savings: 1,944,000 gallons * 0.5 = 972,000 gallons

Therefore, based on the given assumptions and considering a range of adoption rates, the gasoline savings across Denver may range from 194,400 gallons to 972,000 gallons per week.
