#### 4.2.2 Accessibility Value  
To carry out the classification of the evaluated blocks, an accessibility value must be assigned to each block according to the established criteria for each variable (width of the pedestrian area, obstacles on the sidewalk, pavement condition, and presence of pedestrian ramps). The value of each of these variables will be weighted according to the previously defined ranges to determine the accessibility level of each block. The procedure for assigning values is presented in the following steps:  
* Step 1: Analysis of the variables. For each block, the corresponding values are assigned to the evaluated variables (width of the pedestrian area, obstacles, pavement condition, and pedestrian ramps). The values are assigned according to the established ranges:  
* Poor (0 < A < 0.4) indicates very poor accessibility conditions. * Fair (0.4 < A < 0.8) indicates acceptable accessibility but with certain limitations. * Good (0.8 < A < 1.2) reflects good accessibility conditions. * Very Good (1.2 < A < 2) indicates optimal conditions and accessibility for all pedestrians. * Step 2: Application of the values to each variable. * Width of the pedestrian area. Assign a value based on the sidewalk width:
* If the width is less than 90 cm, the minimum value (0) is assigned. * If the width is between 90 and 150 cm, an intermediate value is assigned. * If the width is greater than 150 cm, the maximum value (2) is assigned. * Obstacles on the sidewalk. Evaluate if there are obstacles that reduce the pedestrian space:
* If there are obstacles that reduce the pedestrian area to less than 90 cm, assign the value 0. * If there are obstacles but they do not affect the minimum width of 90 cm, assign the value 1. * If there are no obstacles, assign the maximum value (2). * Pavement condition. Evaluate the state of the pavement:
* If the pavement is highly deteriorated with multiple unstable areas, assign the minimum value (0). * If there are some unstable areas but fewer in number, assign an intermediate value. * If the pavement is in excellent condition, assign the maximum value (2). * Presence of pedestrian ramps. Evaluate if there are adequate pedestrian ramps:
* If there are no pedestrian ramps, assign the minimum value (0). * If there are ramps but with a width of less than 1.2 m, assign an intermediate value. * If the pedestrian ramps are adequate and have a width greater than 1.2 m, assign the maximum value (2). * Step 3: Calculating the accessibility of each block. Once the values for each variable have been assigned, the score for each block is averaged. This score will represent the accessibility level of each block on a scale from 0 to 2. Based on this score, an overall classification will be assigned to the block: \(\bigcirc\) Poor if the score is between 0 and 0.4. \(\bigcirc\) Fair if the score is between 0.4 and 0.8. \(\bigcirc\) Good if the score is between 0.8 and 1.2. \(\bigcirc\) Very Good if the score is between 1.2 and 2. The results of the accessibility value are presented in Tables 1 and 2. According to the results obtained from the evaluation, it is clear that the majority of the blocks assessed, using the numerical method based on the elements considered (such as sidewalk width, presence of obstacles, pavement condition, and pedestrian ramps), fall within the higher end of the accessibility scale. Specifically, most of the blocks are classified in ranges 3 and 4, corresponding to \"Good\" and \"Very Good\", respectively. In more detailed terms, when examining the classification of the 16 evaluated blocks, 13% of them, which is equivalent to 2 out of the total 16 blocks, were classified within range 3, indicating \"Good\" accessibility. These blocks met most of the desired accessibility criteria but may still have room for improvement in some areas. Meanwhile, the remaining 87% of the blocks, which equals 14 out of the 16 evaluated blocks, were classified in range 4, signifying \"Very Good\" accessibility.
