This chapter does not provide final guidance as to whether a TIA is recommended. TxDOT and applicable agencies may request a traffic study for various scenarios that are not accounted for in this chapter. TxDOT’s Access Management Manual contains guidance in Chapter 3 on different engineering studies, including when TIAs are typically requested. A link to the TxDOT Access Management Manual can be found in
