Quantitative Factors
Unlock Audio Lesson
Let's start with the quantitative factors that affect mode choice. These factors are measurable and play a significant role in a traveler's decision-making process.
What are the main quantitative factors we're looking at?
Great question! The main quantitative factors are relative travel time, relative monetary costs, and the availability and cost of parking. For instance, longer travel times typically deter people from certain modes.
Can you explain how parking costs influence people's decisions?
Absolutely! If parking is expensive or hard to find, travelers might choose public transport instead. For memory, you can remember 'TIME' - Travel time, Investment (cost), Mode availability, and Ease of parking.
Qualitative Factors

Now let's shift to qualitative factors. These are less measurable but very essential for user experience.
What kinds of qualitative factors should we consider?
We consider comfort and convenience, reliability and regularity, and security. For example, travelers might prioritize comfort over cost.
How do we measure something like comfort?
That's indeed tricky! While comfort is subjective, surveys and user feedback can provide insights. Remember 'CRRS' - Comfort, Reliability, Regularity, Security as you study these factors.
Importance of Considering Both Factors

Finally, why are both quantitative and qualitative factors important in transportation planning?
Will ignoring one set of factors lead to poor planning?
Exactly! Balancing both ensures better transportation systems and helps in accommodating user needs effectively. Use the acronym 'BOTH' - Balance Of Time & Health to recall this concept.
So if we aim to enhance public transport, we need to optimize both cost and comfort?
Precisely! Summarizing from today, we explored quantitative and qualitative factors, discussing their importance in influencing transport mode choice decisions.
Introduction & Overview

Quick Overview
Standard
The section delves into the characteristics of transport facilities that impact mode choice decisions. It categorizes these characteristics into quantitative aspects, such as travel time and costs, and qualitative aspects, like comfort and reliability, illustrating their significance in travel demand modeling.

Characteristics of the Transport Facility
In transportation planning, understanding the characteristics of transport facilities is essential for assessing mode choice. These characteristics can be categorized into two main groups: quantitative and qualitative factors.
1. Quantitative Factors
Quantitative factors are measurable and contribute directly to the traveler's decision-making process:
- Relative Travel Time: This includes in-vehicle, waiting, and walking times for various modes, influencing the desirability and efficiency of each mode.
- Relative Monetary Costs: This aspect encompasses all travel expenses such as fares, fuel, and parking fees, which directly impact a traveler’s choice of transport.
- Availability and Cost of Parking: The ease and expense of parking can greatly influence whether an individual opts for public transport vs. private transport.
2. Qualitative Factors
Qualitative factors are less tangible but equally influential:
- Comfort and Convenience: These characteristics impact a traveler's experience and satisfaction with the chosen mode.
- Reliability and Regularity: Consistent schedules and dependable services are essential for promoting public transportation usage.
- Protection and Security: A safe and secure travel environment is paramount for travelers, especially in public transport.
Understanding these characteristics allows policymakers and planners to offer better transportation solutions that address the needs and preferences of various users.

There are two types of factors. One is quantitative and the other is qualitative. Quantitative factors are:
(a) relative travel time: in-vehicle, waiting and walking times by each mode;
(b) relative monetary costs (fares, fuel and direct costs);
(c) availability and cost of parking.
Detailed Explanation
This chunk focuses on quantitative factors, which are measurable elements that influence the choice of transport mode.
- Relative Travel Time: This includes how long it takes to travel in a vehicle, how long you wait for the transport, and how long you walk to and from stops. The total time can affect whether a person chooses one mode of transport over another.
- Relative Monetary Costs: This involves looking at the costs associated with travelling by different modes, including fares, fuel expenses, and any additional direct costs involved in the journey.
- Availability and Cost of Parking: The ease of finding parking and the cost associated with it can heavily influence whether someone chooses to drive versus using public transport.
Examples & Analogies
Consider a scenario where a person needs to travel to work. If they can drive and park easily without cost, they might prefer driving. But if public transport is faster despite added waiting time, they may opt for that instead. For example, if the subway station is just a 5-minute walk, but parking is $20 a day, they might choose the subway to save money.

Qualitative factors which are less easy to measure are:
(a) comfort and convenience
(b) reliability and regularity
(c) protection, security.
Detailed Explanation
Qualitative factors are more subjective and harder to quantify but are equally important in mode choice.
- Comfort and Convenience: This concerns how pleasant the travel experience is. A comfortable ride with ample seating can sway a person toward public transport.
- Reliability and Regularity: This relates to how dependable and consistent the transport service is. If a bus comes on a regular schedule and is typically on time, people are more likely to use it.
- Protection and Security: This factor considers how safe a passenger feels while using a mode of transport. If individuals feel safe and secure when using public transportation, they are more likely to choose it over alternatives.
Examples & Analogies
Imagine taking a subway versus driving. Although driving might be quicker (quantative), a person may choose the subway due to a lack of traffic and hassle (qualitative), not to mention feeling safer when in a crowded subway train compared to driving through a busy city where they might feel more vulnerable.

A good mode choice should include the most important of these factors.
Detailed Explanation
It's essential to create a valid and effective mode choice model by combining both quantitative and qualitative factors. Understanding how these elements interact can lead to better planning and choices in transportation. For example, if a mode of transport is affordable and fast (quantitative), but also comfortable and safe (qualitative), it is likely to attract more users.
Examples & Analogies
Think of a smartphone comparison. A phone with excellent specs (processing speed, camera quality) might attract tech-savvy users, but if it's bulky and uncomfortable to hold (comfort), many might stick with a slightly less powerful but more user-friendly device. Similarly, in transportation, a balance of cost, time, comfort, and safety will drive user decisions.
