## 5 Results and Discussion
In other vehicles, powered wheelchairs used by male users, the highest accessible route was R10 with a score of 0.51, as shown in Figure 11, and the lowest route was R9 with 0.21, as was the case for male users of artificial limbs. The two most important criteria for them did not differ from those for male users of artificial limbs, as the first most important criterion was the length and the second was slope. The absence of a footpath was next and the last one was the number of junctions. The two most important criteria, length and slope, were rated very low and low, respectively, in this route, and in the highest-rated accessible route, the length rating was high, and the rest were medium. As for females, R5 was the most accessible route, with a score of 0.50. The most important criteria for them were as follows: absence of footpath, followed by length, slope, and number of junctions. The most important criterion, the absence of a footpath, was rated high, while the other criteria, such as the number of junctions, were rated very high; the slope was rated as medium and the length was rated very low. R7 was the least accessible, with a score of 0.22, indicating a low level of accessibility. The evaluation of the most important criteria illustrated that the absence of footpath and length were low, while the slope and number of junctions ranged

The accessibility results for manual wheelchairs used by males and females were close and similar to those for all participants. For a high level of accessibility, the weaknesses in the ten routes must be considered and improved. The slope criterion evaluations in Table 4 reveal a common denominator among the routes, with most slopes receiving ratings ranging from very low to medium. The slope criterion is considered the least evaluated compared to other criteria, and there is an urgent need to improve it based on survey responses and route evaluations. R5 rates the best route at 3.79%, while R8 rates the worst route at 8.16%, which is considered highly steep. ADA requirements stipulate that the slope of footpaths must not exceed 5% to provide easy movement without excessive effort so as not to cause fatigue and reduce dependability. Figure 12 illustrates the five cases of slopes identified [58]. The first case, which is absolutely the best, is for the footpath's surface to be flat. The second case, where the slope is less than 4%, is suitable and manageable for mobility. In the third scenario, a slope of 5% is deemed acceptable. However, if the slope reaches 8%, individuals with disabilities will require assistance to overcome it, and the most dangerous scenario is if it exceeds 12%. The improvement target for this criterion is for all routes to be at an acceptable and best level so that the slopes are 5% or less, as shown in Figure 13, where it appears that there are only three routes at the required level below the improvement target limit, which are R5, R6, and R10, and others that exceed the improvement target limit need improvement.

Other criteria, such as length, the most critical criterion for manual wheelchair users, were extended for all routes except for R10, which was 398 m with a high rating, and R3, which was 568 m with a medium rating. According to the survey, the remaining routes received low to'very low' ratings. Figure 5 illustrates that the majority (35%) of respondents cannot move more than 100 m, and 31% cannot travel distances greater than 300 m. The percentages were lower for longer distances. Absent, or recently started, public transport in most of Hail and Qassim cities can reduce the fixed distance between an origin and a destination, reducing the distance PWD must travel.
