Book Description
Smart growth developments are high density developments which have a mix of land uses like residential, retail, commercial for example, on the same location thereby providing good potential for interaction between them. Due to the proximity of these different land uses, there exists convenience for other modes of transport like walking, biking and the use of transit. The ITE Trip Generation manual, which has been the traditional source of trip generation data, is mostly based on suburban dispersed study sites where there is limited potential for using other modes of transport other than automobile. Therefore, relying on the conventional ITE Trip Generation manual for estimating trip generation rates for smart growth areas do not produce accurate results. Using suburban development trip rates for smart growth settings might overestimate the trip generation rates resulting in more transportation infrastructure than required. This project focuses on establishing the trip generation rates for smart growth settings in California focusing on the land use coffee shops and creates a mode share database of the different trips generated. The total vehicle trips from this study are compared with standard ITE trips to see if there are any differences in the rates. The methodology adopted in this study utilizes the same methodology adopted by Caltrans for the study on trip generation in urban infill areas and by UC Davis for the study on smart growth trip generation in California. The methodology uses a combination of intercept survey and in and out door counts to determine the trip generation rates of coffee shops. This methodology counts the trips generated by walking, biking and transit in addition to auto trips. It also helps in calculating the auto trip generation which uses shared parking and off-street parking which is common in smart growth sites. Six coffee shops in and around San Jose, California were chosen as study sites, and data were collected in May 2013. The responses from intercept surveys were combined with door count data to estimate the peak-hour trips along with the mode share during the peak hour. Results reveal that on an average, ITE overestimates peak-hour trips by 34% during the AM peak hour and by 18% during the PM peak hour at smart growth coffee shops. There is also a noticeable contribution of trips by other modes such as walk (24%), bike (2%) and transit (2%). As smart growth developments are becoming more and more popular, future studies with more sites focusing on a particular land use is recommended to gather more identified trip generation results of smart growth sites.

Book Description
The purpose of this research project is to evaluate the accuracy of industry accepted vehicle trip generation methods for smart growth developments in the Sacramento Region. An existing smart growth development located at the intersection of 65th Street and Folsom Boulevard in Sacramento was chosen as the subject development. Estimates of generated vehicle trips for the daily, A.M. peak hour, and P.M. peak hour time periods were calculated using the Institute of Transportation Engineers (ITE) Multi-Use Trip Generation Method and the San Diego Association of Governments (SANDAG) Trip Generation for Smart Growth Method. The results were compared to observed vehicle trips at the subject development. The observed vehicle trips at the development were counted using automatic vehicle counters (pneumatic tubes) at each of the two driveways that provide ingress/egress to the development over a 24-hour period. The vehicle trip generation estimates were calculated using the direction provided by the Institute of Transportation Engineers and the San Diego Association of Governments. The inputs required to complete the calculations were obtained by contacting local government agencies and the owners and operators of the development. The required data included Geographical Information System (GIS) files to estimate employment and transit, which were provided by the Sacramento Area Council of Governments (SACOG) and Sacramento Regional Transit (RT). United States Census information was available online, and land use characteristics were provided by the owners and operators of the development. In the A.M. peak hour, the 516 vehicle trips estimated using the ITE Multi-Use Method was 108% of the 479 observed vehicle trips. The 322 vehicle trips the SANDAG Trip Generation for Smart Growth Method estimated in the A.M. peak hour was 67% of the 479 observed vehicle trips. In the P.M. peak hour, the 361 vehicle trips the ITE Multi-Use Method estimated was 42% of the 853 observed vehicle trips. The 472 vehicle trips estimated using the SANDAG Trip Generation for Smart Growth Method was 55% of the 853 observed vehicle trips. In the daily time period, the 6,250 vehicle trips the ITE Multi-Use Method estimated was 125% of the 4,976 observed vehicle trips. The 6,189 vehicle trips estimated using the SANDAG Trip Generation for Smart Growth Method was 124% of the 4,976 observed trips. The SANDAG Trip Generation for Smart Growth Method requires significantly more effort to produce vehicle trip generation results compared to the ITE Multi-Use Method. The SANDAG Trip Generation for Smart Growth Method requires research and analysis to identify the inputs its spreadsheet tool uses to calculate vehicle trip reductions for smart growth developments, which include using the U.S. Census, GIS software which is not readily available to all users to perform the analysis, and detailed and sophisticated analysis of travel analysis zones and regional transit travel times. The ITE Multi-Use Method is based on an initial calculation of vehicle trips and two easily obtained internal capture rate tables provided in the ITE Trip Generation Handbook.

Book Description
The sixth edition of Trip generation includes several significant changes in format and content as compared to the fifth edition. To facilitate use of the document, the overall publication has been repackaged into three volumes: Volumes 1 and 2, containing land use descriptions and data plots, and a User's guide, containing the general introductory, instructional and appendix material. A significant amount of new data has been collected since the publication of the fifth edition. Data from more than 750 new studies have been added to the existing database for a combined total of more than 3,750 individual trip generation studies.
