This paper reviews and analyzes the land use documentation included in various editions of the Trip Generation manual published by the Institute of Transportation Engineers (ITE) concerning Land Use: 530 (High School) and Land Use: 550 (University) and spanning an assessment period of more than 20 years. Remarks and recommendations are made on the possibility of using the rates proposed in the 2012 edition of the manual to estimate the number of automobile trips generated by high schools and universities in Brazil. Overall the study showed that such rates lead to overestimates of trips as compared to those actually observed in Brazilian institutions. Furthermore, it was found that the rates and models adopted in each successive edition of the ITE manual are obtained by aggregating the more recent studies to the database of the preceding edition without discarding the older studies so that more recent efforts to alter the modal distribution for trips generated by such sites are not fully captured in the newest editions.
