Restrict network dataset segments on certain days

ArcMap 10.7.1 network analyst extension

I want to restrict network dataset segments on certain days, i.e every Tuesday a road is closed due to a reason.

The approach that i made was as follows:

Added 3 new fields in my network feature class (RestrictedDay, RestrictedFrom, RestrictedTo)

Then i created a descriptor called RestrictedDayDESC (unknown units Integer Data Type)

Type Field

Value expression

import time def X (RestrictedDay): if RestrictedDay is None: retVal= -1 else: retVal = time.strptime(RestrictedDay, "%A").tm_wday return retVal

Then i added a restriction called RestrictedDays (unknown units Boolean Data Type)

and a parameter called RestrictedDayDESC

Finally i created a function evaluator

If i create a network analyst layer through arcmap the logic works. an i can change parameter value through Attribute Parameters tab

So far so good but we work with python and i cannot find a way to pass the current day parameter to

MakeRouteLayer method

The travelmode is as follows

{ "name": "Car Oneways", "type": "AUTOMOBILE", "description": "Models the movement of motorbikes and other similar small automobiles and finds solutions that optimize travel distance. Travel obeys one-way roads and follows other rules that are specific to cars.", "impedanceAttributeName": "Minutes_Traffic", "timeAttributeName": "Minutes_Traffic", "distanceAttributeName": "Length", "restrictionAttributeNames": ["Barriers", "Cycleway", "Footway", "Oneway", "Path", "RestrictedDays", "Steps", "Tolls"], "attributeParameterValues": [{ "attributeName": "Oneway", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Barriers", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Cycleway", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Footway", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "OnewayHighways", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "OnewaySelective", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Path", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Steps", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "Tolls", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "RestrictedDays", "parameterName": "Restriction Usage", "value": -1 }, { "attributeName": "RestrictedDays", "parameterName": "RestrictedDaysDESC", "value": 3 }], "useHierarchy": true, "uturnAtJunctions": "esriNFSBAtDeadEndsOnly", "simplificationTolerance": null, "simplificationToleranceUnits": "esriUnknownUnits" }

To summarize

how can i change (u'RestrictedDays', u'RestrictedDaysDESC'): 3, to current day number?
