Band 5+: The charts below show the information about a US bus company between 1999 and 2003. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

THE BAR CHARTS ILLUSTRATE THE PROPORTION OF BUSES FULFILLING THEIR SERVICE CRITERIA, ADHERING TO THE TIME OF ARRIVAL OVER A FOUR YEAR OERIOD. ALSO THE FEEDBACK FROM THE TRAVELLERS WAS MEASURED IN TERMS OF COMPLAINS EVERY YEAR. NOTICEABLY, THE BUSES HAVE PROVIDED AN OUTSTANDING SERVICE IN THE BEGINNING AND THE END OF THE PERIOD, THAN EXPECTED. HOWEVER THE PERFORMANCE LEVELS ARE EVIDENT TO HAVE DECLINED SINCE THE BEGINNING OF THE TWENTY-FIRST CENTURY. BUT NOT MUCH. A HIGHER VOLUME OF POPULATION HAD COMPLAINS WITH THE TRANSPORT FACILITY IN THE LAST TWO YEARS. WHICH PEAKED IN THE FIRST YEAR OF THE MODERN PERIOD, AND FELL SHORTLY IN THE FOLLOWING YEAR, UNTILL THE NEXT TWO YEARS IN WHICH THE LEVELS OF NEGATIVE FEEDBACK FROM THE CUSTOMERS INCREASED EVENTUALLY.

IN THE BEGINNING OF THE PERIOD, MORE THAN 80% OF THE BUSES EXCEEDED THE DECIDED NORMS OF SERVICE IN TERMS OF PUNCTUALITY. HOWEVER, IN THE FORECOMING THREE YEARS, THE LEVELS OF STANDARDS DECREASED WITH THE EFFICIENCY OF THE TRANSPORT TO REACH TO THE DESTINATION ON TIME. PROPORTION OF BUSES ANTICIPATED TO REACH ON TIME HEAVILY DECLINED TO HALF OF THE INITIAL NUMBERS, FROM 80% IN 1999 TO 40% IN 2001. THE EXPECTANCY RATES OF THE BUSES TO BE PUNCTUAL ALSO SPIKED DOWN HEAVILY TO LESS THAN 305 in 2000. BY THE NEXT TWO YEARS THE VOLUME OF BUSES EXPECTED TO REACH THE PLACE ON TIME SHALL DECREASE TO 40%, AFTER REMAINIG CONSTANT FROM 2001. IN CONTRAST, THE PERCENTAGE OF BUSES DELIVERING MORE THAN DESIRED OUTCOMES SHALL CONSISTENTLY INCREASE FROM ALMOST ABOVE 40% IN 2001, TO REMAINING THE SAME IN 2002 AND FINALLY PEAKED TO ALMOST MORE THAN 75% IN THE FINAL YEAR.

THE NUMBER OF COMPLAINS RECIEVED FROM THE CITIZENS HAVE NOT FLUCTUATED MUCH OVER THE PERIOD, MORE THAN

AVERAGE OF 50 COMPLAINS FROM THE COUNTRY WERE RECIEVED IN ALL THE FOUR YEARS. WITH THE HIGHEST NUMBERS FROOM THE 200. WHEN ALMOST 100 CLIENTS WERE DISSATISFIED WITH THE TRANSPORT SERVICE, WHICH SLOWLY ROSE TO 120 INDIVIDUALS IN THE FINAL YEAR. IN 1999 AND 2001, THE TREND HAS WITNESSED THE LOWEST PROPORTION OF NEGATIVE FEEDBACK
