+```
+In the joint tour party composition model, the makeup of the travel party (adults, children, or
+mixed - adults and children) is determined for each joint tour.  The party composition determines the
+general makeup of the party of participants in each joint tour in order to allow the micro-simulation
+to faithfully represent the prevalence of adult-only, children-only, and mixed joint travel tours
+for each purpose while permitting simplicity in the subsequent person participation model.
+
+The main interface to the joint tour composition model is the
+[joint_tour_composition](activitysim.abm.models.joint_tour_composition.joint_tour_composition)
+function.  This function is registered as an Inject step in the example Pipeline.

+
+The joint tour destination choice model operate similarly to the usual work and
+school location choice model, selecting the primary destination for travel tours. The only
+procedural difference between the models is that the usual work and school location choice
+model selects the usual location of an activity whether or not the activity is undertaken during the
+travel day, while the joint tour destination choice model selects the location for an
+activity which has already been generated.
+
+The tour's primary destination is the location of the activity that is assumed to provide the greatest
+impetus for engaging in the travel tour. In the household survey, the primary destination was not asked, but
+rather inferred from the pattern of stops in a closed loop in the respondents' travel diaries. The
+inference was made by weighing multiple criteria including a defined hierarchy of purposes, the
+duration of activities, and the distance from the tour origin. The model operates in the reverse
+direction, designating the primary purpose and destination and then adding intermediate stops
+based on spatial, temporal, and modal characteristics of the inbound and outbound journeys to
+the primary destination.
+
+The joint tour destination choice model is made up of three model steps:
+  * sample - selects a sample of alternative locations for the next model step. This selects X locations from the full set of model zones using a simple utility.
+  * logsums - starts with the table created above and calculates and adds the mode choice logsum expression for each alternative location.
+  * simulate - starts with the table created above and chooses a final location, this time with the mode choice logsum included.
+
+Joint tour location choice for [multiple_zone_systems](multiple_zone_systems) models uses [presampling](presampling) by default.
+
+The main interface to the model is the [joint_tour_destination](activitysim.abm.models.joint_tour_destination.joint_tour_destination)
+function.  This function is registered as an Inject step in the example Pipeline.  See [writing_logsums](writing_logsums) for how
+to write logsums for estimation.

+In the joint tour person participation model, each eligible person sequentially makes a
+choice to participate or not participate in each joint tour.  Since the party composition model
+determines what types of people are eligible to join a given tour, the person participation model
+can operate in an iterative fashion, with each household member choosing to join or not to join
+a travel party independent of the decisions of other household members. In the event that the
+constraints posed by the result of the party composition model are not met, the person
+participation model cycles through the household members multiple times until the required
+types of people have joined the travel party.
+
+This step also creates the ``joint_tour_participants`` table in the pipeline, which stores the
+person ids for each person on the tour.

+The school escort model determines whether children are dropped-off at or picked-up from school,
+simultaneously with the chaperone responsible for chauffeuring the children,
+which children are bundled together on half-tours, and the type of tour (pure escort versus rideshare).
+The model is run after work and school locations have been chosen for all household members,
+and after work and school tours have been generated and scheduled.
+The model labels household members of driving age as potential ‘chauffeurs’ and children with school tours as potential ‘escortees’.
+The model then attempts to match potential chauffeurs with potential escortees in a choice model whose alternatives
+consist of ‘bundles’ of escortees with a chauffeur for each half tour.
+
+School escorting is a household level decision – each household will choose an alternative from the ``school_escorting_alts.csv`` file,
