a) Objectives of the local bus operator for replacing the old bus fleet with a brand new, autonomous, electric bus fleet could include:

1. Improving operational efficiency: Autonomous electric buses can improve operational efficiency by reducing driver-related costs and increasing fuel efficiency.

2. Enhancing passenger experience: Autonomous electric buses provide a quieter and smoother ride than traditional buses, which can enhance the passenger experience and attract more riders.

3. Reducing environmental impact: Electric buses produce fewer emissions compared to traditional internal combustion engine buses, which can help reduce the environmental impact of transportation.

4. Promoting innovation and technological advancement: Replacing traditional buses with autonomous electric ones is an innovative move that showcases the company’s commitment to technological advancement.

b) Different types of assessments that should be conducted to determine whether replacing the old bus fleet with new autonomous electric buses is a good idea include:

1. Technical feasibility assessment: This assessment should evaluate whether it is technically feasible to replace the old bus fleet with new autonomous electric vehicles. It should consider factors such as charging infrastructure, maintenance requirements, and technology readiness.

2. Economic viability assessment: This assessment should evaluate whether replacing the old bus fleet with new autonomous electric vehicles makes economic sense for the bus operator in terms of cost savings, revenue generation, and return on investment.

3. Environmental impact assessment: This assessment should evaluate how much greenhouse gas emissions will be reduced by introducing autonomous electric vehicles and what other environmental impacts they may have (e.g., disposal of batteries).

4. Safety assessment: This assessment should evaluate how safe these autonomous vehicles are in different weather conditions and traffic situations. It should also analyze potential safety issues associated with human-machine interactions during boarding or de-boarding from these vehicles.

5. Social acceptance assessment: This type of assessment aims to identify any social barriers or concerns about the use of autonomous electric vehicles by passengers or other stakeholders.

c) To address some problems that may arise from assessments, the bus operator should consider taking the following measures:

1. Addressing charging infrastructure: The bus operator should ensure that there is adequate charging infrastructure to support the new electric buses. This may involve building new charging stations or partnering with third-party providers.

2. Providing training and support for drivers: While autonomous vehicles do not require a driver on board, the bus operator may still need drivers to operate these vehicles in certain situations (e.g., emergency situations). Therefore, training and support programs should be provided to existing drivers for them to adapt to new roles.

3. Ensuring transparency and communication: The bus operator needs to communicate clearly with stakeholders about how autonomous vehicles will work, their safety features, and how they will impact jobs.

The implications of these measures for deployment and adoption by the bus operator may include increased costs associated with charging infrastructure development and driver training programs. However, these measures are essential for ensuring successful deployment of autonomous electric buses while addressing social barriers or concerns about this technology from passengers or other stakeholders.
