    1. in the middle of the week and Saturdays

      Shortenings can complement bus bunching analysis and should be related with them, so no need for week/hour evolution.

      Actually, there should be a chart with % shortenings vs % bus bunching, to study correlation between the two variables.

      ALTERNATIVE: Difference between days is residual. If y starts on 0 and line is smoother, there won't be a visual difference throughout the week.

    2. actually data suggests the opposite occurs

      Since there is no statistical evidence of a tendency, the chart would be better explored in 4 quadrants (P50 dividing them), and exploring how the 4 groups are characterized

      For each quadrant, choose some routes to explore in the text as examples, and for those provide chart with nr of buses bunched (y, comulative) per stop number (x)

      ALTERNATIVE: try to normalize per route extension (m). Y would be % of services bunched per km and then there should be a tendency

    3. 8.38% of the services are bunched

      This is a good value, since Carris average is around 7. Having a value close to the average means that the edge cases happen outside the bus lanes.

      Also, compute for other big axis that do not have bus lanes, to validate that bus bunching occurs more there: * Morais Soares * Avenida do Brasil

    4. Stops with highest bus bunching index

      It's ok to show only worst cases, but specify (top 5 or top 10)

      Complement with histogram of % per stop (to affirm that for 25% of stops, 1 in every 10 buses is bunched)

    5. Examples of routes with high RBI²

      Add columns with route extension and commercial speed (extension/duration), for easier interpretation

      Show also routes with low values

      Add histogram with all routes, for people to have the big picture

    1. improve their decision-making

      Retirar ónus da decisão do motorista

      Tipificar e automatizar respostas a disrupcoes no serviço como redundância á falta de resposta da central
