## 9 Physical Considerations
### Other Vehicles  
Working with comparable passenger vehicles is also possible as claimed in Figure 14. For instance, the MotoEV Electro Transit Buddy 9 Passenger Shuttle [59] is characterized by the following parameters:  
* Model: MotoEV Electro Transit Buddy 9 Passenger Shuttle;
* Passenger capacity: 9 people;
* Vehicle dimensions: 13.9\({}^{\prime}\) L \(\times\) 4.88\({}^{\prime}\) W \(\times\) 6.72\({}^{\prime}\) H;
* Gross vehicle weight: 3855 Lbs (\(\approx\)1750 kg);
* Speed: up to 25 mph;
* Range: up to 50 miles (full capacity);
* Climb: 20% grade (full capacity);
* Electric motor: 5 KW (6.7 Hp);
* Maxload: 2100 Lbs (\(\approx\)953 kg);
* Ground clearance: 7\({}^{\prime\prime}\) (\(\approx\)17.7 cm);
* Batteries: QTY 12-Trojan 105 or US2200;
* Suspension: independent/rear steel plate suspension;
* Drive: rear-wheel drive. Without details, the set of these parameters are approximate to the ones shown in Table 4, and adjustments can be made in the designs to produce results as those already offered here. Figure 13: Distribution of sensors in a sedan car according to [58]. In this proposal, the plan is to follow that rule for the front detector in the automated vehicles. **10. Preparing for the Future of Automated Transportation: Off-Road Displacement of Vulnerable People**  
At the beginning of this document, the authors tried to motivate the real need for autonomous vehicles, type GC or PSV, that can transport vulnerable passengers according to the constraints given in Section 3.2. It was shown that not only legislation about driver's license holding for GCs and PSVs is an issue, but also the fabrication standards of such vehicles. Furthermore, the principles and codes for placing off-road speed-calming devices plus the random emergence of pot holes induce the action of automating the car. In spite of the fact that this work was devoted to automatically dealing with bumps/humps by the elevation of the framework of the car, it was remarked that the path following will be solved elsewhere because this problem is well known. In this short section, the intention is to emphasize the future (not very far away) implications of automated cars. Besides, it is also remarked that (at least) the U.S. Government is already taking actions on the matter [60]. Among the many implications of automation, in [60], it was reflected that automation represents tremendous possibilities for improving the mobility of travelers with disabilities, as remarked in the present study. Through the Accessible Transportation Technologies Research Initiative (ATTRI), the Department of Transportation fosters initiatives with various government organizations in conjunction with the disabled community to develop research that allows this vulnerable group to travel comfortably and safely. It is also important to mention that disability involves not only mobility, vision, and hearing, but also cognitive impairment. Special needs is defined as an individual with a mental, emotional, or physical disability. Although the Society of Automotive Engineers (SAE; [[https://www.sae.org/](https://www.sae.org/)]([https://www.sae.org/](https://www.sae.org/)) (accessed on 13 February 2022)) [60] identifies six levels of driving automation, the automatic suspension involves such a self-performed process, and the given definition about these terms are the following:  
* Automation: Use of electronic or mechanical devices to operate one or more functions of a vehicle without direct human input. Generally applies to all modes;
* Automated vehicle: Any vehicle equipped with driving automation technologies (as defined in SAE J3016). This term can refer to a vehicle fitted with any form of driving automation (SAE Level 1-5);
* Automated Driving System (ADS): The hardware and software that are collectively capable of performing the entire dynamic driving task on a sustained basis, regardless of whether it is limited to a specific operational design domain. This term is used specifically to describe a Level 3, 4, or 5 driving automation system (SAE J3016).
