                                                                                    23 August 2019, Bangkok, Thailand

             land uses can create proximity between residences,   of street segment and intersection spaces. The map
             employment,  and  goods  and  services,  reducing   can  be  created  to  indicate  the  overall  pedestrian
             vehicle trips and miles traveled and increasing active   environment evaluation results,
             transportation  such  as  walking  and  biking.  In
             addition,  commercial  buildings  providing  services
             were found to have a positive effect on pedestrian
             frequency.

             2.1.5 Perceived Safety
                    The  perceived  safety  parameter  enables
             strategic  design  that  integrates  street  lighting  and
             commercial  uses  to  prevent  crimes  by  improving
             walk-safety  awareness  through  the  physical
             characteristics of the environment. The cleanliness
             of a street, which includes graffiti, litter garbage and
             broken  glass,  as  well  as  pedestrian  lighting  are
             important factors found in many walkability audits.
             Roadway  and  sidewalk  construction  can  disturb
             pedestrian flow and create hazards for pedestrians.
             Construction  zones  can  pose  safety  issues  for
             pedestrians  by  blocking  the  sidewalk  with  heavy
             machinery and creating alternate routes that are less
             accommodating for pedestrians.

             2.2 Scoring
                 Indicator  scores  for  each  indicator  category
             were created based on expert interviews, including
             city  and  transportation  planners  and  consultants,
             regarding   their   importance   to   pedestrian
             environmental factors. Final scores were informed
             by  n=10  expert  s.  For  each  PEQS  indicator,
             respondents were asked two questions:
                 1)Indicators: Overall importance for pedestrian
                 quality.   Response   optionsincluded   not
                 important,  somewhat  important,  important,
                 very important, and essential, on a scale from
                 1-5.
                 2)Indicator  response  categories:  Relative
                 importance of indicator response categories for
                 pedestrian  quality.  Within  each  indicator,
                 indicator response categories were assessed on
                 a scale of -5 to +5 (from extremely detrimental
                 to ideal for pedestrians). Scale of -5 to +5 was
                 re-scaled the responses to a scale from 0-10 for
                 the  final  indicator  response  category  scores,
                 and weighted indicator response categories by
                 the  median  value  of  their  survey  response
                 scores.

             2.3 Visualization the PEQS
                    Using  a  street  segment  and  intersection
             identifier, a visual map was created that incorporated
             the evaluation results for a selected region consisting
